MARS-HV

Medium Voltage Load Bank

Description
The Mars-HV is a self-contained load
bank to 15KV utilizing the
Simplex Saturn Load
Module with onboard dry-type power
transformer. It is a
freestanding, skidded
unit consisting of three
principle sections:
1. High voltage
section consisting
of main input
power terminals,
high voltage: 480V
3-phase power
transformer, low
voltage output
terminals, and
outputs to load cell
2. 480V, low voltage
resistive load section
consisting of one
700-1200KW forcedair cooled load cell
3. Control Section
All control circuits and
control power supplies
are powered internally. The Mars-HV
requires connection of a 3-phase feeder
only.
Load circuits and cooling fan operate at
480V; control circuits operate at 120V.
Input disconnects, fuses, lightning
arrestors and potheads available as
options.
