Sager Power Systems
A Profile in Power Supply Distribution
In June 2014, North American IP&E distributor Sager Electronics acquired PowerGate LLC, a Silicon Valley-based power supply distributor. PowerGate LLC (PG)
was founded by two power supply industry veterans, Ed Kramer and Paul
Christiansen in 2005 as an exclusive power supply distributor supporting design
engineering with AC/DC power supplies, DC/DC converters and factory modified
standards and custom solutions. Their knowledge, experience and connections
within the power supply industry helped PG grow significantly over a relatively
short period, leading to the acquisition by Sager Electronics in 2014.

In the years preceding the acquisition of PowerGate LLC, Sager Electronics was a
growing presence in the power supply business and saw a unique growth opportunity in an area the distributor deemed “underserved.” Sager Electronics developed its power supply strategy as a means to differentiate itself both in the marketplace and with its parent company, TTI Inc., a leading distributor in the world
of IP&E.
Sager Power Systems (SPS) was officially launched in Q1, 2015 as a specialized
group within Sager Electronics dedicated to power solutions. Following the acquisition of PG, SPS was created to preserve and build upon the power specialization
of PG while leveraging the strengths of Sager Electronics. Today, SPS stands as
a premier power supply distributor with a comprehensive offering of:

AC-DC power supplies

DC-DC converters

Medical power supplies

Industrial power supplies

LED power supplies

External power supplies

Sager Power Systems is now
the largest North American distributor of Mean Well, the largest standard off-the-shelf
power supply company in the
world.
Following the PowerGate acquisition last year, Sager Electronics
looked to further cement its position in the power supply market. In
July 2015, Sager Electronics acquired Norvell Electronics, another
highly regarded power supply dedicated distributor and value added
reseller. (Please see press release on page 6). The Norvell acquisition completed the back-end capabilities for SPS, bringing an ISO
9001 approved facility capable of configuring safety agency approved modular power supplies and developing custom power subsystems.
With Sager's acquisition of PG and Norvell, and its formation of
Sager Power Systems, the group has taken an aggressive, positive
and expanded role to penetrate and support mid-tier & emerging
accounts using power. The company has assembled one of the
strongest and largest dedicated groups of power professionals capable of delivering and servicing any type of power supply to any number of accounts within North America:



There are 19 Power Systems Sales Engineers, dedicated to only
selling power, covering the entire North American market, with
as many as 3 to 4 Sales Engineers in major markets including
Northern California, Southern California, New England and Texas.
There are 13 inside power sales specialists, who support and sell
only power, helping to recommend solutions and take orders for
immediate shipment as well as schedule production level orders.
There is a team of 16 design engineers and technicians supporting engineered, custom power sub-system solutions and configuring modular power supplies located in Texas.
In addition to the dedicated power team, Sager has 120 additional
field and inside salespersons also supporting power, along with industry leading interconnect and electromechanical solutions.
With all its power expertise and a wide array of power supply vendors, Sager Power Systems can match the right suppliers to the
right applications. In addition to offering standard solutions, SPS can
also provide two types of value-added solutions:


It can provide configurable/modular power supplies, which are
standard components assembled to create a custom power supply assembly that are safety agency approved. Small quantity
can be configured and shipped within 72 hours if required.
It can design “custom” power subsystems, done at the distributor
premises, designed and built for each customer’s unique set of
engineering requirements.

Sager Power Systems
A Profile in Power Supply
Distribution
While SPS offers a wide variety of
standard products and valueadded solutions from its own
premises, it can also offer solutions for factory modified standard solutions. Such modifications
are needed where a standard
product, with minor modification
(s), will meet the engineering
need. This is very typical for medium size OEM customers.
According to Paul Christiansen,
Vice President of Supplier Marketing & Product Management of
Sager Power Systems: “... Sager
Electronics brings a new power
strategy to the market. Sager is
changing the “P” in IP&E from
“Passives” to “Power”. Along with
its strong sales in interconnect
and electromechanical components, Sager is transitioning
power to be the 3rd major category on our line card…”
The newly established Sager
Power Systems (SPS) group consists of a trifecta of distribution
expertise in power supplies:
Sager Electronics, PowerGate LLC
and Norvell Electronics. With this
combined expertise in selling
power supplies, SPS has become
a major force in power supply distribution with a goal to grow in
2015 to the #2 DTAM position for
power.
SPS's marketing and selling strategy is based on:









National network of dedicated Power Systems Sales Engineers
Aggressive pricing for medium to high volume requirements
Specialized inventory management programs
Knowledgeable Inside Sales Specialists only supporting power
In-house application support

Normally these companies are focused on their own intellectual
property. For such customers, SPS provides a slew of products and
services including design and applications engineering expertise, in
addition to supply chain management and on-time delivery of the
right products, for the right application, in the right quantities. SPS
also offers expertise in safety and compliance regulations as well
as industry trends, areas that are ever changing and continuously
evolving.
Primary markets consist of:
 Industrial/Instrumentation

Fairchild Launches the Industry’s First Mid-Voltage MOSFET in an 8x8 Dual Cool Package
Reduced Footprint of Dual Cool™ 88 MOSFET Boosts Power Density and Improves System Efficiency With a low Parasitic Package
SAN JOSE, Calif.--Fairchild (FCS) launched its industry-leading midvoltage MOSFET technology in a Dual Cool™ 8mm x 8mm package. The
new Dual Cool 88 MOSFET gives power conversion engineers a first-ofits-kind alternative to bulky D2-PAK packages at half the size and with
higher power density, superior efficiency and better cooling via air flow
above and beneath the package.
“Fairchild's Dual Cool 88 products played a central part in delivering a
winning solution to one of our key customers,” said Patrick del Castillo,
CEO, Castle Creations, Inc. “The low profile, small footprint, and low Rds
(on) of the Dual Cool 88 MOSFETs enabled us to provide the smallest
board size and lowest solution cost, while delivering the highest efficiency
in high power BLDC motor drive applications.”
“Between meeting industry regulations and consumer demand, manufacturers need to address the growing worldwide trend toward smarter,
smaller and more efficient consumer and industrial devices,” said Mike
Speed, Director of Product Marketing at Fairchild. “The Dual Cool 88
MOSFET delivers superior performance, power density and efficiency in a
package half the size of D2-PAK devices to enable manufacturers to develop more efficient products while reducing their cost and improving reliability.”
Manufacturers can increase the efficiency of DC motors while reducing
costs using the Dual Cool 88 packaging rather than MOSFETs in D2-PAK
packages. Greater efficiencies with lower cost are enabled by the Dual
Cool 88’s packages advantages over D2-PAK, including smaller size,
thinner profile, and 93 percent lighter in weight, making them ideal for
weight-sensitive applications such as drones and aero-modeling.
Compared to D2-PAK, the Dual Cool 88’s package also delivers faster
switching, less EMI along with the higher power density, and lower parasitic losses. The reduced parasitic losses are achieved using source clip
not wire bonds, ensuring high pulse current with 63 percent lower source
inductance compared to D2-PAK devices.
The Dual Cool 88 is also easier to store, ship and handle as it is highly
resistant to moisture, which often causes damaging delamination during
storage. Its excellent MSL1 rating allows it to resist moisture without requiring the protected packaging of D2-PAK devices.

Intersil Delivers First Encapsulated 80A Digital Power Module
ISL8273M provides highest power density POL solution for advanced FPGAs, processors and memory
The 80A ISL8273M further distances itself from competitive digital power modules by delivering 2x higher output current.
Its proprietary High Density Array (HDA) package offers unmatched electrical and thermal performance through a singlelayer conductive package substrate that reduces lead inductance and dissipates heat primarily through the system
board. The ISL8273M is built on Intersil’s proven, fourth generation digital controller technology and is pin-for-pin compatible with the 50A ISL8272M. It expands Intersil’s existing 6A - 50A digital power module family, giving customers an
easy migration path to higher current rails. These fully encapsulated power modules are compatible with all industry pick
and place equipment for full manufacturing automation.
“With advanced FPGAs and processors occupying more of the PCB real estate and requiring higher input current levels
at lower input voltages, the demands on POL power converters are being pushed to the limit,” said Mark Downing, senior
vice president of Infrastructure and Industrial Power Products at Intersil. “The 80A ISL8273M gives our customers the
power density they need, along with excellent thermal and electrical performance, on-the-fly power supply optimization,
and real-time system monitoring and control.”
Through a PMBus-compliant interface, the ISL8273M module’s digital control technology provides precise sequencing,
full telemetry and system monitoring.
The ISL8273M can also start up and operate in pin-strap mode using six external resistors for setting default configurations such as Vout, soft-start, under-voltage, switching frequency and current sharing. This allows designers to power up
the modules during the development phase without using PMBus or requiring any programming.
