Dreiphasige Stromversorgungen mit reduzierter Pulsation

Three-phase DC supplies with Graetz’s bridge rectifier with connections B6 or B12 are designed for users who need for their receivers an unstabilized DC voltage.
DC-supplies are equipped with a LED indicating the current state of the operation. Standard designs of power supplies are prepared for mounting on mounting brackets.
On request power supplies can be supplied with two types of protection: against fault and overload protection.

Power supplie EZ3W - with smoothing capacitor, used for I_N ≤ 30 A
Power supplie EZ3P - with 12 - pulse circuit, used for I_N> 30 A

*) - for product design with climatic/environmental class C2/E1 (maritime design W/3 or tropical design T/3) the letter "M" or "G" ought to be added depending on final application
**) - this table was prepared based on the technical specification for power supplies with voltage ratio 400//24V DC operating under normal conditions. For other conditions and data the values may change

Note:

Manufacturer reserves the right to make changes resulting from the continuous development of products offered.

If requested in advance, it is possible to manufacture a power supply in other version.
