A LINE OF POWER BOARDS FOR REFRIGERATION SYSTEMS


A line of power boards for refrigeration systems with three-phase compressors up to 10 HP to be linked to a thermostat, thermo-regulator or out-of-room control unit. An electromechanical timer is incorporated for timed defrosts.

Applications • Control of three-phase static or ventilated refrigeration units up to 10 HP, with electric or off-cycle defrost linked to a thermostat, thermo-regulator or out-of-room control unit that issues a cold request. Main characteristics • Direct control of compressor, condenser fans, compressor oil element, defrost elements, evaporator fans, solenoid valve and all standard-compliant electrical safeguards. • Compact unit with self-extinguishing ABS housing panel and IP65 protection rating plus circuit breaker on front of panel. • Electromechanical timer for timed defrosts. • System status indicated by LED icon. • Can be controlled by thermostat, thermo-regulator or out-of-room control unit. • Can house thermo-regulator on front of panel. Options • Installation of magnetothermic circuit breakers instead of fuses. • Compressor shutdown in pump-down mode.
