About the units

EA-PS 800 19“ AC/DC PLUG IN POWER SUPPLIES 80W

General

The power supplies of the series EA-PS 800-80 are designed as plug-in units for 19“ draw-out systems according

to DIN 41494. They are assembled in a stable housing with a aluminium front panel in dimension of 3U / 8HP. The

electrical connection is realised via a H15 plug, according to DIN 41612. The power supplies are manufactured

for highest quality and accordance to safety standards EN 60950 (TÜV) and UL 1012 and the EMI standard EN

55022.

Input voltage

All power supplies are equipped with an active PFC (power factor correction) for use on a wide input voltage

range. Thus the units can be used on mains AC voltages from 90V up to 264V and 45Hz up to 65Hz or DC

voltages from 90V up to 360V. Input surge current will be limited to <23A by a NTC resistor. Input voltage peaks

are suppressed by a VDR resistor.

Outputs

All output voltages are adjustable in the dened range through the holes in the front panel and by using a screw-

driver. The outputs are voltage regulated, overload and short-circuit protected. A green LED for each output

signalises, that the respective output is working correctly. To protect connected loads and equipments against

overvoltage, an overvoltage protection circuit (OVP) is implemented. Also, an overtemperature protection feature

(OT) is present. If the overtemperature limit is exceeded, all outputs will be shut down.

Mechanical dimensions

Important information

Before the unit is put into operation, it is necessary to inspect the housing and electrical connectors for signs of

physical damage. If any physical damage has been found, the equipment may be not connected to the mains.

Repair and services must only be carried out by qualied and authorised personnel.

The unit must only be operated at a grounded mains connection. The natural air circulation may not be impeded.

Distances of 40mm at the top and 20mm at the bottom are recommended as minimum if the unit is operated with

a constant load. The unit may be only used and t into a rack system according DIN 41494.

Attention!! The housing and the front panel can become hot if the unit is in operation.
