EKR30P

EKR30P is a proportional controllers for multistep (up to 5 steps) electric heaters with automatic voltage adaptation.

EKR30P is a proportional controller for multistep(up to 5 steps) electric heaters with automatic voltage adaptation. EKR30P controls the whole load On-Off. The ratio between On-time and Off-time is varied 0-100% to suit the prevailing heat demand. EKR30P is designed only for electric heating control. The control principle makes it unsuitable for motor or lighting control. EKR30P can control with triac output 30kW heater and has four relay outputs for 4 extra load steps control with contactors, on
which can be connected load up to 225kW. Full load can be 255kW. Triac output of EKR30P has zero phase-angle detection to prevent Radio Frequency Interference.
