Portable Load Bank
The Simplex dynaMITE 300
Portable Load Bank provides highly versatile load-test capability
for the manufacturers, distributors and users of small-to-medium
size AC power systems to 300KW nominal.
The dynaMITE 300 is suitable for production line, service
shop or field testing of engine generators, UPS systems, ground
power units, auxiliary power units, static inverters or virtually
any other AC power source. This load bank can be applied to all
common AC voltages to 480V maximum, 50-60-400Hz, single or 3-phase.
The dynaMITE 300 is a fully self-contained test instrument
which includes test instrumentation, connection cables, high
capacity cooling system, rugged load elements, complete load
application control devices, and automatic system protection
devices.
The dynaMITE 300 is compact and fully portable and includes
lifting eyes, forklift channels, and moving handles. Connection
cables are conveniently stowed in a cable compartment behind
a hinged door. All instruments and controls are protected by
hinged panel covers.
