Om EA-PS-7032-20A

The EA-PS 7032-20A is a single-output laboratory DC power supply from EA Elektro-Automatik's PS 7000 A series, rated 0-32 V and 0-20 A.

The design uses a thyristor pre-regulator followed by a linear transistor stage, which keeps ripple very low. It has a temperature-controlled fan. Voltage and current are each set with coarse and fine knobs. The supply works in constant-voltage or constant-current mode, and CV and CC LEDs show which mode is active. Analogue voltmeter and ammeter are fitted (illuminated LCD meters were an option). Over-voltage protection is standard: when the set level is exceeded, a thyristor short-circuits the output in under 1 ms.

A 15-pin Sub-D socket on the front panel accepts 0-10 V signals to program voltage and current and provides 0-10 V monitor outputs. Remote sense is supported. Units can be connected in series or in parallel. The 20 A rating suits higher-current loads such as motors, 24 V systems and burn-in or test-rig supplies.

Vanliga frågor

Can the EA-PS 7032-20A be controlled remotely?

Yes, through its analogue interface. A 15-pin Sub-D socket on the front accepts 0-10 V signals for voltage and current and gives 0-10 V monitor outputs. There is no digital interface.

Can it be paralleled for more current?

Yes. EA states that two or more units can be operated in parallel or in series; in series the output may not exceed 500 V to ground.

What is the difference from the EA-PS 7032-10A?

Same 0-32 V range and controls; the -20A model delivers up to 20 A (640 W) against 10 A (320 W).
