Proportional Control Solid State Relay, Analog 4-20mA or 0-10VDC Input Introduction:

  • The proportional control solid state relay control signal is one of 4-20mA, 0-5VDC or 0-10VDC. Output voltage is from 0VAC to 380VAC(or simply 0%-100% voltage outputs).
  • Load current can be 10A, 40A, 60A, 80A, 100A, 120A. If control signal is 4-20mA, the model is SSR-(current)LA, if 0-5VDC or 0-10VDC, the model is SSR-(current)VD.
  • Compared with manual potentiometer control solid state voltage regulator, this one is automatic control. The 4-20mA, 0-5VDC or 0-10VDC signal can be from analog signal generator or proportional output pid temperature controller.
  • This proportional SSR is composed of a thyristor switch circuit, a phase-shift circuit, a hysteresis circuit, an overvoltage absorption circuit.
  • It adopts a flame retardant plastic shell, epoxy resin potting, and threaded terminal wiring.
  • When in use,  we only need to input 0~5VDC or (0~10VDC) voltage or 4-20mA current. It can replace contact type voltage regulators in many occasions.
  • Widely used in petrochemical equipment, food machinery, packaging machinery, textile machinery, stage lighting to adjust power, voltage, temperature, brightness, and speed.
