| 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. All doors are provided with latches and weather resistant gasketing for security and protection during shipment and inclement weather. 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. TECHNICAL DESCRIPTION: Continuous Rating 120/208 or 240/416 volt, 3-phase, 4-wire 120 or 240 volt, single phase, 2-wire at 50-1000cycles per second. Fixed Loads 3, 6, 9, 12 or any combination up to 30KW in multiples of 3 Variable Loads 0-3 KW combined fixed and variable control of load between 0.5 kw and 33 kw, single phase or balanced 3-phase operation with fixed and variable load switches in proper condition Temperature Limits 25 degrees farenheit (-4C) to +125F(52C) at relative humidity to 100% Altitude Range Sea Level to 8000 feet (240 meters) Acceleration Limits 2.6G momentarily applied to any three major axis; in both directions.
