Description
POW-12-ZC-2L – Three Phase SCR Power Switch suitable for Three Phase Heaters connected in 3 Wire Star without Neutral or close Delta with 2 leg control (1.5KW/3A to 18KW/30A @ 415VAC).
Libratherm offers ready to use Zero Cross Over SCR Power Switch model POW-12-ZC for 3 phase electrical heating loads. This power module comprises Libratherm make triggering card to generate pulse-width modulated (PWM) zero cross over firing pulses to control suitably rated back to back connected SCRs – duly mounted on the aluminum heat sink with heavy-duty input and output connectors for heaters and AC power supply. The entire assembly is mounted in MS powder-coated enclosure, which in turn can be easily mounted inside the closed control panel as desired. This Three Phase Zero Cross Over Controlled Thyristor Power Switch model POW-12-ZC accepts both analog and a digital control signal from DDC, PLC, or PID controller to switch the AC power. The PWM duty cycle is adjustable by the user using the Onboard potentiometer.
Key Features:
- 3 Amps to 30 Amps capacity (1.5KW to 18KW – Three Phase Heaters).
- 3 phase versions (2 leg or 3 leg control).
- Auto / Manual Operation.
- Accepts (4-20)mA / (0-5)VDC / (0-10)VDC or 8 to 24VDC pulse as the control signal.
