SBK-150VA/SBK-200VA Three Phase Control Transformer

Description

SBK-150VA/SBK-200VA Three Phase Control Transformer

Capacity of 50000VA and below, suitable for input voltage 1000V and below AC 50-60Hz circuit. It can work continuously for a long time under the rated capacity and is widely used in machine tools and mechanical equipment as a control power supply for general electrical appliances, local lighting and indicating power supply.

·The altitude does not exceed 2000 meters;

·The ambient air temperature is -25ºC to +40ºC, and the average value of 24 hours does not exceed +35ºC

·The relative humidity of the air does not exceed 90% at +25 ° C, and does not exceed 50% at +40 ° C

·Where there is no violent vibration and shock vibration, where there is no rain or snow attack:

In the medium without explosion risk, there is no gas and conductive dust enough to corrode metal and destroy insulation
