The family of Precision Bipolar System Supplies consists of three voltage sources (6129C, 6130C and 6131C) and one current source (6140A). They provide easy, fast and accurate programming of their dc outputs, with many features oriented specifically towards efficient integration in automatic systems.

Isolation
All digital inputs are completely isolated from the analog outputs.

Programmable Current Limit (Voltage Source)
Valuable loads can be protected by a user programmable current latch. Output power goes to zero when the latch circuit is tripped. The reaction time to the latch can be adjusted, if desired, to avoid tripping when reprogramming with a capacitive load. There is also a fixed current limit at 110% of rated current output.

Current Monitoring Terminals (Voltage Sources)
A voltage is available at the rear barrier strip which is proportional to the output current.

Analog Input
An ac signal may be injected into the output amplifier to simulate various noise and ripple conditions.
