LOAD CUBE

2500KW Load Bank System

Description
The Simplex Load Cube is an ultralarge capacity , fully portable, resistive/
reactive Load Bank System intended
for eld use in testing, maintenance
and performance proving of large
generating systems. The Load Cube is
rated 2500kw, 1875kvar at 400-600v
commercial AC voltages. The Load
Cube is typically used to test large
diesel generators, turbines, paralleled
generators and shipboard generators.
With a purpose-built design consisting
of rugged, all-welded, tubular steel
frame, heavy gauge steel sides,
guarded hinged doors, power-operated
ventilation louvers, the Load Cube
is far superior to designs which use
refurbished and modied ISO shipping
containers. Four-sided access allows
ready service of all components and
facilitates the ultra-compact design.
Compact and easily transportable, the
Load Cube is ideal for rental use. With a
footprint of only 8 x 10 feet and a height
of less than 9 feet, the Load Cube is
easily transportable by conventionalheight at bed trailer. Lifting eyes and
forklift channels simplify site movement.
The Load Cube utilizes digital load
control for direct access of load
values, block transitions, and user
programmable automation. A selection
of digital power meters and data
acquisition software is available.
The Simplex Load Cube represents the
ultimate technology in large generator
load testing performance.
