VT7001A
Power Supply Module
The VT7001A module can be used to control up to 2 power supply inputs of an ECU (e.g. terminals 15 and 30). As an alternative, 2 ECUs may be supplied separately, e.g. for testing differences in voltage supplies.
Characteristics
Module Features
- 2 external power supplies can be connected
- Internal power supply generates voltage for the ECU from the VT System power supply
- 2 external and 1 internal power supplies may be connected to the 2 outputs to the ECU in various combinations
- Ground lines of outputs can be interrupted (line break of terminal 31)
- Relays for producing short circuits between the output lines
- Measurement of output currents over a very wide range
- Measurement of input and output voltages
- Control of two external power supplies via control voltage or via electrically decoupled serial interfaces
- Generation of arbitrary control voltage curve
- Serial interface for driving an external display
- Hardware synchronization with Vector network interfaces
- The module supplies ground and battery voltage to the bus bars at additional pins
