CONFIGURABLE POWER CONTROLLERS WITH SERIAL COMMUNICATION IN MODBUS RTU
Modular monophase power controller with heatsink, 25A / 480VAC (25A at 40°C, volta­ge range 90 - 530 VAC). Control inputs: digital, programmable analog V, I, Potentiometer. Firing type configurable for: ZC “zero crossing”, BF “burst firing”, HSC “half single cycle”, PA “phase angle”.
• Configurable analog control input (0- 10V, 4- 20mA)
• Faceplate protection: IP20
• Overvoltage protection
