ELECTRICAL CIRCULAR DUCT HEATERS

Heaters EKA with integrated controller

Heaters EKA with integrated temperature controller EKR-KN... (See Fig. 11) can be controlled in
five different ways depending on control type:
Type EKA NV –
potentiometer on the top of the heater casing for
Type EKA NI – external wired remote
Type EKA NIS – external wired remote
Type EKA ESKM – external wired remote PWM (ON/OFF: ON(6...24)VDC) signal for temp. control
Type EKA MB – external wired remote temperature control via Modbus RTU protocol (RS485)
Electrical duct heaters EKA with integrated temperature controller EKR-KN... works by PID
regulator. That enable fine temperature control. Controller EKR-KN... controls load by Triacs without
moving parts, which causes no-noise commutation.
