Product Overview
The Energy Absorber Test System includes power supplies and a regenerative energy absorber with a rating of 400VDC at ±150A. The system consists of DC power supplies, an AC distribution and interlock system, an energy absorber chassis and an absorber load resistor chassis. The power sources are equipped with a remote control option allowing control via GPIB or with front panel controls in local mode. The operation of the specific parts of the system is described in the sections below.
DC Power Supplies
The power supplies consist of two model types each rated for 0-400VDC at 75A. The SGI supply includes a GPIB programming interface and operates as the Master supply. The SGA supply is used as a Slave, operating as a voltage controlled current source. This Master/Slave operation is used to provide up to 400V at 150A for 60kW of output power. By operating in a Master/Slave configuration, the supplies operate as one unit that can be controlled from the Master unit through either local control or IEEE-488 operation.
The DC power supplies contain a provision for voltage and current readback. The current readback on the front panel of the supplies is set up so that the SGI supply indicates the sum of both supplies. As used in this system, the power supply current monitoring indicates the actual power supplies output current. Regenerative current is not conducted through the power supplies due to a blocking diode in the Energy Absorber chassis so the system current readback is available separately.
Energy Absorber Load Chassis
The Energy Absorber Load chassis contains the regenerative resistive load element. The load consists of numerous high power resistors connected in series/parallel banks, creating a total resistance of approximately 1.5 Ohms at 30kW continuous and 60kW peak.
