Capacity Detail

Description

Simplex Load Banks utilize “Powr-

Web” load elements. The “Powr-Web”

is an advanced design, air-cooled

power resistor specifi cally designed for

application to Load Bank systems. The

“Powr-Web” is conservatively operated

at half the maximum temperature rating

of the alloy and features a short-circuit-

safe design based on continuous

mechanical support of the element by

high temperature, ceramic clad stainless

steel rods. The “Power Webs” are

assembled into discrete trays which are

assembled in a vertical “stack.” Each

tray in the “stack” is independently

serviceable without disturbing adjacent

trays.

Digital Load Step Control

Nominal 5.0 kw resolution: direct enter

any load value and controller will apply

load within nominal 5kw resolution

Digital Load Calibration
Versus Voltage

Controller automatically calibrates loads

for reduced voltage operation.

Voltage: Dual Voltage: 240/480V AC,

3-phase Operational at any voltage to

480V AC maximum, single or 3-phase

Frequency: 50, 60 Hertz standard

Connection: 3-wire plus ground

Time Rating: Continuous

Ambient Air Temperature: 120°F max

Fault Rating: 200KAIC

Insulation Rating: 600V, 302°F

Net Weight:
dynaMITE 300: 800 lbs.
dynaMITE 400: 1,000 lbs.
