Temprature Sensors

الوصف

This is a Fridge controller with four temperature bands each with a fixed temperature differential and with compressor ON/OFF Control. The controller also provides four alarm /status LED indication and an automatic defrost. (Automatically defrosts the freezer compartment for *0 minutes in every *2 hours) The controller uses extremely high reliability Thermometrics fridge probe sensors (*0K NTC Thermistor). The operating voltage of the controller is from *0 VAC to **0 VAC with low voltage and high voltage cut OFF. Electrical specifications: Power supply Voltage : **0 VAC/*0Hz Voltage operating range : *0 to **0VAC Operating Temperature : **5°C to **5°C Relay output contact capacity : *6 Amps at **7 VAC (Inductive load) Sensor specification: Temperature sensor : NTC Thermistor (*0K) Beta Value : ***7+/- 1% at *5/*5°C Response time : > *0 seconds Operating Temperature : **0°C to + *5°C Insulation resistance : > **0 Mega ohms at **0VDC
