Tiristorių kontaktoriai - DAC

Tiristorių kontaktoriai - DAC | DACPOL SERVICE



Thyristor contactors  -DAC.

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
