The DAC-1 Series contactors are adapted to operation in industrial conditions. Their main virtues are high durability,overvoltage endurance,no switching overvoltages and silent operation. Application : switching on voltage of : - resistance furnaces - heating tubes - discharge lamps - direct motor start-up
Operational advantages of semiconductor contactors: - plain and handy fixing and wiring in power cubicles - high level of operational safety ensured by screening of current conducting elements - simplicity of fuses replacement - visual indication of control correctness - trouble-shooting without the use of measuring instrument - easy repair in case of failure
Extraordinary stability is obtained by: - thyristor selection according to expected values of load and work conditions - the use of a heat sink in order to provide optimal operation temperature - the use of RC snubbers for protection against switching overvoltages
