GTT

MONOPHASE SOLID STATE POWER UNITS WITH HEATSINK AND
ANALOG CONTROL

Monophase solid state power unit for resistive loads, complete with heatsink, “fast-cycling,
zero-crossing” firing to drive double SCR connected in antiparallel; proportional analog
control with 0...10VAC, 0...20mA, 4...20mA, potentiometer signal. DIN rail attachment,
signal and diagnostics LEDs.

• Analog control input 0- 10VAC, 4- 20mA

• Faceplate protection: IP20

• Internal MOV overvoltage protection

• Power control: Fast-cycling, Zero-crossing mode

• Nominal working temperature 40°C
