The EA-4000 is a universally applicable power supply with a rotary transformer for a continuously adjustable output voltage of 0...260VAC at 3A or 4.5A. A further transformer provides a fixed output voltage of 230VAC at 2A. The AC outputs are available on safety sockets on the front panel. The output values are displayed on digital illuminated LCD meters on the front.
The DC output voltage can be continuously adjusted between 0 and 32V. A regulated fixed voltage of 3-6V/2A is available via safety sockets on the front and can be adjusted with a screwdriver. Various AC output voltages are also available.
The EA-STT 2000-3 and 4,5 are isolated rotary transformers with an output of 0 to 260VAC at a load of up to 1200VA.
