Heater Control Panel
Our heater control panels are design to provide accurate and safe controls for an electric heater. The internal of the control panels consist of three independent but inter-related systems. They are control system, safety shutdown system and power distribution system. The control portion would handle all logic, remote interface and temperature control loop. The safety shutdown system is design to monitor and shutdown the heater during unsafe operation. Finally, the power distribution portion would regulate the electrical power to the heater based on the requirement from the control system.
Supply voltage can vary from single phase 120/240VAC to three phase 380/415/480/600 and 690VAC. Harmonics can be an issue with the power distribution system if the heater is the major load on the power distribution load. Symptoms of harmonic issues include flickering of facility lighting, unstable generator operation, overheating, and et cetera.
