USC-1 Universal- SIMPLE- Control : Specification
USC-1 REVOLUTIONARY, UNPARALLELED SIMPLICITY in SETUP and INSTALLATION, and
PERFORMANCE, make the new 2005 USC-1 controller simply the most COST-EFFECTIVE, Advanced
Technology with .5% Metering accuracy over –40 +85 Celcius. Simplicity, performance and reliability are the 32year Hallmark of ICMI, and its USC-1, UVR-1 and UVR-1 LTC Advanced Control Technology products.
The USC-1 Universal SIMPLE Regulator Control is a microprocessor-based single-phase tap changer voltage
regulator control with comprehensive metering capability. The USC-1 is compatible with all popular single-phase
step voltage regulators from US. Manufacturers. The differences in regulator types (i.e. operation counters, neutral
polarity, holding switch) are handled through USC-1 hardware, and setup program options.
Regulation Set Points (Forward/Reverse Flow)
• Bandcenter (100.0 to 135.0 V)
• Bandwidth (1.0 to 6.0 V)
• Time Delay (5 to 180 sec.)(Fwd /Set)
• Line Drop Compensation
♦ (R) Resistive (-24.0 to +24.0 V)
♦ (X) Reactive (-24.0 to +24.0 V)
Reverse Power Flow –3 Modes

THE REVOLUTIONARY NEW USC-1 is a COPYRIGHT PROTECTED, designed and engineered,
proprietary technology control product of ICMI. The technology may not be duplicated, copied, or reverseengineered, or used in any form without the express license issued by ICMI to third parties.
USC-1 comes standard with Factory backed 2 year limited warranty. (Five Year Ltd. warranty available).
FEBRUARY 24, 2005 ANSI-IEEE Certification of RFI-SWC C-37.90-1&2 (2002-2004 RF
Standards) AEP-Dolan Tech Center-Columbus, Ohio.
The USC-1 front panel USB Port to Program Control & enable Software revisions as features
or enhancements are added. The USC-1 control is designed to facilitate a FIVE Input XIOLite remote- control functionality . The main CPU processing circuit board inside the USC-1 is
designed to enable future change-out expansions with more powerful processors and larger
program and data spaces. This provides a cost-effective upgrade path, insuring the flexibility
of the USC-1 and protecting the original investment. I.C.M.I. reserves the right to modify this
