Avtron IHT
Intelligent Hand-Held Terminal
Fast and Accurate Testing with
Maximum Efficiency.
Key Features
•Remote Operation with full
3-Phase Instrumentation
•Network Capability for Control of
Multiple Load Banks
•Modbus Interface Provides
Integration with PLC, HMI, or
SCADA Systems
An Avtron Load Bank with Intelligent Hand-Held
Terminal (IHT) Sigma™ load control and instrumentation
is the leader in simplicity, ease of use, and accuracy.
The Sigma 2 brings a powerful, yet cost effective solution to today’s power testing requirements.
It provides high level instrumentation, data capture, and verification.
The Sigma 2 load bank module is installed in the load bank with Voltage and Current Transformers (VTs and CTs). It is the control interface for all the functions within the load bank.
• Robust Purpose Designed Microprocessor-Based Module with Industrial Connectors and
LED Status Display
• Usage Counters provide Information on Individual Contactor Operation, Element Run
Times, Overall Power-on Time, Load-on Time, and KWH
• 24 VDC Supply Voltage with 24 VDC Input and Outputs
•Rugged and Lightweight Design
with Sealed Membrane Controls
includes a 30 ft. [10 meter]

Intelligent Hand-Held Terminal
IHT Hardware
The IHT provides full load control and 3-Phase
instrumentation.
The IHT provides enhanced load control and
instrumentation.
• Robust Hand-Held Terminal Housed in
Industrial Polycarbonate/Polyamide Enclosure with PVC Hand Grips providing IP65
Protection
• Operation and Data Capture
• All instrumentation measurements are
made using high accuracy voltage and
current transformers located within the
load bank. This information is processed
digitally, using high speed sampling of the
raw data. This provides full 3-phase, high
speed, true RMS measurements with high
updates rates to class 0.5 accuracy.
• Display Pages Show All the Main
Electrical Parameters
• Calculation of rated line current and
kilowatts
• The Displays are designed to Simplify the
Testing, Setup, and Adjustment of GenSets and UPS Systems
• No need for any pre-calculations
• Membrane Keyboard and Back-Lit
Graphic LCD
• Large Display of Voltage and Frequency
Assist with Initial Set-up
• Comprehensive overload and stall protection is provided, based on the rating of the
supply-on-test.
• Performs transient load tests
• Automated load control provides multiple
timed load steps including manual override and cyclic testing
• In-built test editors allow easy set up
of load including percent load, power
factor, and time.
• Manual control via selection of kW,
percent load, or kVA.
• Simple plug/socket connections allow
multiple Avtron Load Banks of differing
capacities and combination: resistive, inductive, or combined may be connected
and controlled from one Intelligent
Hand-Held Terminal (IHT) or PC (with
optional software).
• Operation up to a 3,280' from load bank.
• Multilingual user interfaces include English, French, German, Spanish, and Italian.
Weight & Dimensions (approx.)
3.75 lbs. [1.70 kg.]
9.31 x 7.50 [236.47 x 190.50]
including lugs: 9.31 x 8.25 [236.47 x 209.55]
Options
When carrying out full-load testing, one page
shows all the true RMS 3-Phase measurements
of voltage (V), frequency (Hz), current (A), power
(both KW and KVA), and power factor (Cos Ø).
For transient-response testing, the voltage
and frequency of the last load change are
captured and displayed on the dynamic graph
including maximum and minimum data.
• Site Load Correction (SLC) Automatically
Prevents Problems Associated with Light
Loading
• SIGMA™ PC Load Control Software
Specifications are subject to change without notice.
All dimensions are in inches [millimeters].
Load selection is displayed in a “popup” window over the instrumentation while the load
is being changed.
The status line includes the elapsed time
since the last load was applied.
