Proportional Control Solid State Relay, 4-20mA, 0-10VDC Input

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

• Lorentzzi® proportional control solid state relay control signal is one of 4-20 mA, 0-5 VDC or 0-10 VDC. The output voltage can be 0-250 VAC or 0-480 VAC (or simply 0%-100% voltage output).
• Load current can be 10 A, 25 A, 40 A, 60 A, 80 A, 100 A, 120 A. If control signal is 4-20 mA, the model is SSR-(current)LA, if 0-5 VDC or 0-10 VDC, 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 0-10 VDC 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 0~5 VDC or (0~10 VDC) voltage or 4-20 mA 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.
