Controller for solar system Tech Controllers ST-402N PWN solar/collector controller

SOLARCONTROLLER TECH ST-402N PWM FOR SOLAR COLLECTORS ST-402N type thermoregulator is designed to support solar collector installations for various system configurations Product features SOLARCONTROLLER TECH ST-402N PWM FOR SOLAR COLLECTORS ST-402N type thermoregulator is designed to support solar collector installations for various system configurations This device controls the operation of collector pumps (or a pump and a valve) based on the measurement of solar battery temperatures and the temperature of the buffer storage (two tanks) Optionally, there is the possibility of connecting an additional device: a circulation pump, an electric heater or sending a signal to the central heating boiler for heating Control of the circulation pump and transmission of the ignition signal to the central heating boiler is possible directly from the controller; An additional signaling relay is required for heating control The controller is suitable for operating the PWM pump and allows the pump speed to be adjusted. Features of the controller: Large, clear LCD display Collector temperature sensor Temperature sensor of the heat storage unit The housing is made of high-quality materials Functions performed by the controller: Pump control (or pump and valve) Control of pump operation with a PWM signal Support and operation of the solar system for nine system configurations Protection against overheating and Freezing the collector There is the possibility of connecting an additional device: a circulation pump, an electric heater or sending a signal to the central heating boiler to heat it up Product parameters: Supply voltage: 230V/50Hz +/- 10% Maximum power consumption: max. 4W Ambient temperature: 5 ÷ 50 °C max load on each output: 1 A Measuring accuracy: 1 °C Temperature resistance of the sensors: -30 ÷ 180 °C Fuse link: 3.15 A Temperature setting range: 8 ÷ 90 °C
