Three-phase power regulators with a softstart - RAC.S

Three-phase power regulators with a softstart - RAC.S

Use:

Soft starting and regulation of supply voltage of: transformers, resistance furnaces with silicon heaters, incandescent lamps. Specialized systems of power regulators causing increase of the receiver voltage from zero to maximum value in a specified time (with the possibility of setting its upper level with a potentiometer) or in the normal control mode - potentiometer power control.

Features:

Long service life, resistance to power line surges, surge-free on/off switching of loads, quiet operation, compliance with PN-EN 60947-4-3.
