The EKC 202 controller can be used for a variety of refrigeration applications. It regulates air temperature and defrosting, as well as more complex control tasks including light and fan control. Its compact design features a 230V AC power supply, 4 relays, and a built-in real-time clock. Additional modules can further expand functionality, such as RS 485 networking or battery backup. Temperature sensors: Type EKS (PTC 1000), AKS (Pt 1000), or NTC. HACCP and EN 441-13: Factory calibration ensures that the measurement accuracy of all EKC 202 controllers, when used with a Pt1000 sensor, exceeds the requirements of EN 441-13.
