VANEAIMS HD703 Digital Temperature Controller NTC 10K Thermostat Relay Switch AC85-265V -20°C to 99.9°C

VANEAIMS HD703 Digital Temperature ControllerA high-precision microcomputer thermostat designed for automatic heating and cooling control in incubators, aquariums, refrigerators, boilers and other temperature-control equipment.Product Features✅ Automatic Heating & Cooling ControlSet the start and stop temperatures to automatically control heating or cooling equipment.✅ NTC Temperature SensorUses an NTC 10K B3950 thermistor probe for accurate real-time temperature detection.✅ Wide Temperature RangeSupports temperature measurement and control from -20°C to 99.9°C.✅ Independent Start & Stop SettingsSeparate displays and buttons allow easy adjustment of the start temperature and stop temperature.✅ Adjustable Delay FunctionStart and stop delay time can be set from 0 to 999 seconds to reduce frequent switching.✅ Clear Digital DisplayDisplays the measured temperature, start temperature, stop temperature and relay operating status.✅ Stable Relay OutputSupports up to 5A / 250V resistive load for compatible heating and cooling devices.✅ Two Installation MethodsSupports panel cutout installation or adhesive mounting for different application requirements.✅ Simple Wiring DesignTwo terminals for power input and two terminals for controlled load output.SpecificationsBrand: VaneAimsModel: HD703-NTCProduct Type: Digital Temperature ControllerInput Sensor: NTC 10K ±1%, B3950Temperature Range: -20°C to 99.9°CMeasurement Accuracy: ±0.5 F.S ±1 DigitControl Mode: Upper and Lower Temperature Limit ControlDelay Time: 0-999 SecondsOutput Type: Relay OutputContact Capacity: 5A / 250V Resistive LoadResistive Load: ≤1000WInductive Load: <200WPower Supply: AC85-265V, 50/60HzOptional Voltage: 12V / 24VProduct Size: Approx. 72 × 72 × 32mmPanel Cutout Size: Approx. 68 × 68mmWorking Temperature: 0°C to 50°CWorking Humidity: 35%-85% RHSuitable ForIncubatorAquarium and fish tankRefrigerator and freezerHeating equipmentCooling equipmentWall-mounted boilerGreenhouseTemperature control cabinetWorking ModeHeating Mode: Set the start temperature lower than the stop temperature. Heating starts below the start value and stops after reaching the stop value.Cooling Mode: Set the start temperature higher than the stop temperature. Cooling starts above the start value and stops after reaching the stop value.Package Includes1 × HD703 Temperature Controller1 × NTC Temperature ProbeNotePlease select the correct power supply voltage before ordering. High-power or inductive equipment may require an additional AC contactor. Installation and wiring should be completed by a qualified electrician.
