About the EA-3021S

The EA-3021S is a single-output laboratory DC power supply from Elektro-Automatik, Germany, marked 'Labor-Netzgerät / Power Supply EA-3021S' with a rating of 0-30 V / 0-10 A.

Voltage (0-30 V) and current limit (0-10 A) each have their own knob, and moving-coil meters show output voltage and current (the ammeter scale reads to 12 A). Output is on + and − terminals with an earth socket between them. A mains fuse holder and a lit Netz/Power switch are on the front panel. The power transistors are mounted on large rear heatsinks.

It is a general-purpose bench supply for test benches, workshops and teaching labs where up to 300 W at 30 V is needed. EA does not publish data for this older model today, so only the panel markings are given.

Frequently asked questions

What are the output ratings?

The front panel marks the EA-3021S as 0-30 V and 0-10 A, adjustable with separate voltage and current knobs.

Can it be controlled remotely?

No interface is visible on the panel; it is a manually operated bench supply.
