The PCU-S1 is a power supply
module with a 3U Eurocard form factor intended for use as a Bus and Bias
supply for the low voltage series of Western Servo Design amplifiers (e.g.,
BLU, LDU and PDU). It can be used in a Eurorack (or "VME") style chassis or
as a stand alone unit.
The PCU-S1 contains a DC Bus unregulated output, a regulated Bias Supply (±12VDC), a 12VDC output for cooling fans, and a built-in shunt regulator. When PWM amplifiers are used, the shunt regulator prevents back EMF generated by the motors from damaging components in the Bus Supply and amplifiers.
An optional backplane is available to allow quick and easy access to the inputs and outputs for the power supplies and the shunt regulator. This greatly simplifies implementing the PCU-S1 in a motion control system.
**All ratings with forced air cooling to maintain 40°C heat sink temperature. Failure to keep constant air flow to the heat sink will reduce the output current capacity and may result in damage to the unit.
