| 4 RELAYS ELECTRONIC REGULATOR |
||||
|
The EXPERT NANO 4CK is a 4 relays electronic regulator designed to control refrigerated counters, display windows and static or ventilated refrigeration units with off-cycle or electrical defrosting in real time (RTC). It is fitted with two analogue inputs for NTC temperature probes, one digital input, four relays for the compressor control, fans, defrosting function and alarm (the defrosting relay can be configured as light command and the alarm relay as AUX) and buzzer. As option the connection to an echo temperature repetition. |

Applications • Can be configured for hot or cold applications. • Defrosting can be configured for off-cycle, heating element or cycle inversion and frequency and durationcan be set. End-of-defrosting can be based on time or temperature. • Clock for programmed defrost (RTC). • Relay for controlling the compressor, evaporator fans, defrosting resistance and alarm (defrost and alarm outputs can be configured like light output). • Key operated manual START/STOP defrosting. • Key operated ON/OFF. • Cold room light ON/OFF switch with key or by means of door switch (if one output is configured like cold room light). • Display/adjustment of temperature with decimal point. • Internal buzzer for acoustic signals. • Flat front surface for easy cleaning anc keys of ample dimension which can be customized with various colours (on request). • High brightness display with increased icons and figures. • PEGO programming philosophy guaranteeing immediate start-up. • IP65 front protection. Two-fold fastening options: clips / screws. • Extractable terminals. • Temperature repeater (optional) . • RS485 serial connection with Modbus-RTU or Telenet protocol. • External transformer (optional). |
