EKR15.1

EKR15.1 is a proportional controllers for electric heaters with automatic voltage adaptation.EKR15.1 can control 15kW heater and has relay output for extra load control with contactor, on which can be connected load up to 12kW. Full load can be 27kW.

EKR15.1 is a proportional controller for electric heaters with automatic voltage adaptation. EKR15.1 controls the whole load On-Off. The ratio between On-time and Off-time is varied 0-100% to suit the prevailing heat demand. EKR15.1 is designed only for electric heating control. The control principle makes it unsuitable for motor or lighting control. EKR15.1 can control 15kW heater and has relay output for extra load control with contactor, on which can be connected load up to 12kW. Full load can be 27kW. EKR15.1 has zero phase-angle detection to prevent Radio Frequency Interference. EKR15.1 automatically adapts its control mode to suit the dynamics of the controlled object . For rapid temperature changes i. e. supply air control EKR15.1 will act as a PI controller. For slow temperature changes i.e. room control EKR15.1 will act as a P controller.
