The universal power supply series EA-3000B from EA offersA flexible solution to common laboratoryAnd workshop requirements.

The adjustable 0-30V and 0-300VAC Voltages of the AC output are alsoavailable as DC, Via a rectifier and switchable capacitor filter.

The model EA-3051B is a stabilised power supply with Power-MOSFET end stages. The output Voltage and output current are adjustable from 0-32V and 0-5A.

The model EA-3050B can deliver 0-30VAC and DC, as well as 0-300VAC and DC. These are selected by an internal range switching.

All models feature for output Voltage and output current illuminated 3-digit Volt and ampere meters.

Galvanic isolation between all outputs and mains input is standard.

The EA-4000B is a universally applicable power supply with a variable transformer for a continuously variable output voltage of 0-260V_AC 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. Output 3 is a regulated voltage of 3-6V/2A.Output 4 is a stabilised power supply with Power MOSFET end stages. Output voltage and output current are here adjustable from 0-32V and 0-5A.Output 5 has several AC voltages with 2A maximum load and are available at miscellaneous output sockets.

The outputs are galvanically isolated from mains supply and against each other. The output values are displayed on digital illuminated LED instruments on the front.

The EA-STT 2000 are isolated, variable transformers with one AC output of 0-260V each, loadable up to 1200VA.
