Solid State Contactors US-H Series

Solid State Contactor US-H Series Features

  • Optimal for injection molding machines, semiconductor production equipment, and other uses with high-frequency heater switching.
  • The load current switching operation is performed by a semiconductor switching element, and as there are no mechanical parts, a long life with highly frequent switching can be achieved.
  • No mechanical moving parts or abrading parts, and therefore no abrasion dust or contact consumption dust, resulting in clean, noiseless, comfortable use.
  • Can be used at 24 to 480 V AC, a wide voltage range for the main circuit.
  • Operation indicator lamp on the front surface allows users to see the operating voltage input status at a glance.
  • Can select control method suited for the applied load, such as a main circuit batch control product suited for three-phase heater control (US-H□ type), or a main circuit individual control product suited for single-phase heater control (US-H□DD type).
