About the EA-PS-7032-10A

The EA-PS 7032-10A is a single-output laboratory DC power supply from EA Elektro-Automatik's PS 7000 A series, rated 0-32 V and 0-10 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 as a constant-voltage source with current limiting or as a constant-current source with voltage limiting, 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, selected with the internal/external mode switch. Remote sense is supported. Several units can be connected in series or in parallel. It is used in test systems, schools, universities and laboratories.

Frequently asked questions

Can the EA-PS 7032-10A be controlled remotely?

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

Can two units be combined?

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

Does it have over-voltage protection?

Yes. OVP is standard and adjustable from 3 V to 35 V; when it trips, a thyristor short-circuits the output in under 1 ms.

What is the difference from the EA-PS 7032-20A?

Both cover 0-32 V. The -10A model delivers up to 10 A (320 W) and the -20A model up to 20 A (640 W).
