New A427A resistive load bank
The unit is sealed in a powder coated weather proof housing.
This resistive load bank is used to test AC generators up to 33kw
This unit comes with the manual still sealed in original packaging.
We guarantee these units to operate in accordance with the manufacturers specifications.
We do accept returns only if the load bank does not operate in accordance with the manufacturers specifications
Electrical Test Set & Load Bank Model # A427A
The Essex Electro Engineers, Inc. Model #A427A, Electrical Test Set and Load Bank, is a portable, skid mounted resistive load unit.
The model A427A operates as a loading and testing device for electrical generating equipment.
The load bank is designed to test the output characteristics of generating plants rated at 120/208 and 240/416 volts, 3-phase, 4-wire; 120 or 240 volts, single phase, 2-wire.
The load bank can operate at frequencies between 50 and 1000 cycles per second.
A completely self-contained unit mounted within a weather resistant enclosure. It is designed to apply various combinations of the resistive load increments to simulate any output load.
Input power terminals are supplied for connection of power cables. Power cables are not supplied with the equipment.
The load Bank can apply 0.5 to 3 kilowatts variable load and 3, 6, 9, 12 KW fixed loads.
When fixed and variable loads are applied in combination, the load bank can supply any load from 0.5 to 33kw on either single or balanced three phase operation.
The major assemblies and components of the test set include a housing, contyrol panel assembly, three power absorbers, variable transformer, contactor, rectifier, output terminals, and a voltage sensing module.
The control panel contains all the neccesary controls for operation of this unit.
Three duct-type 11kw power absorbers provide the resistive load.
They are provided with an integral fan to insure proper cooling, and wind and thermal switches to protect against overheating.
Four stud-type terminals are supplied together with one copper shorting link which tie the studs together for single-phase operation.
The Model A427A is equipped with a voltage sensing module which opens the control circuit and prevents the operation of the test set if the incoming voltage does not conform to the voltage connection of the load bank.
