| Voltage Derating |
|
Standard US models are 480 Volts
delta. Customized units are also available to suit other single
voltages of 208v | 240v | 380v | 440v | 460v Volts 3 phase
60Hz. Dual voltage units are available in
240/480 Volts 3 Phase
(see MWA Series) |
|
An optional auxiliary power
socket is available on single voltage units, to isolate the
load bank fan motor and controls from the diesel generator
supply. The auxiliary connection is made to 3 Phase building
supply. |
|
Load Banks rated at a power
value in kW will provide that value only at the rated voltage
it is
manufactured to. When used on other voltages, the voltage
applied cannot be higher than the rated voltage of the load
bank. Reduced voltage, when applied to the load bank, will
reduce the rated power. Refer to the formula:- KW output = Rated
kW x
(Applied Voltage/Rated Voltage)

Example of load bank de-ratings
is given below. The table is based on a load bank manufactured
to 480 Volts 3PH phase to phase. |
