Technical Specifications

The STC-1000 operates on an AC power supply ranging from 90 to 250V and 50/60Hz‚ or can be powered by a DC supply of 12V or 24V․ It offers a wide temperature control range from -50°C to 99°C‚ making it suitable for various applications․ The controller utilizes an NTC (10K0․5) waterproof sensor with a length of 1 meter for accurate temperature measurement․ Its relay contact capacity is 10A/250VAC for both cooling and heating‚ allowing it to handle a significant load․ The STC-1000 can operate in ambient temperatures ranging from -20°C to 70°C and humidity levels from 20% to 85% RH․

Operating Modes

The STC-1000 operates in two distinct modes⁚ heating and cooling․ It automatically switches between these modes based on the set temperature and the actual temperature measured by the sensor․ The controller utilizes a hysteresis function‚ meaning it allows a temperature difference (also known as the “difference value”) between the set point and the actual temperature before switching modes․ This prevents frequent cycling of the heating or cooling element‚ ensuring a more stable temperature control․ The user can adjust the difference value to suit their specific needs‚ providing flexibility in temperature regulation․

Setting Up the STC-1000

Setting up the STC-1000 involves connecting the sensor‚ load‚ and power source․ The sensor‚ typically an NTC thermistor‚ is connected to the designated input terminals on the controller․ The load‚ such as a heater or cooler‚ is connected to the appropriate output terminals․ Power is supplied to the controller using an AC or DC power source‚ ensuring compatibility with the specific model․ The STC-1000 features two relays‚ allowing you to control both a heating and a cooling load simultaneously․ After connecting the components‚ the controller is ready for configuration and operation․

Connecting the Sensor

The STC-1000 typically utilizes an NTC (Negative Temperature Coefficient) thermistor as the temperature sensor․ These sensors are usually waterproof and come with a cable length of 1 meter․ To connect the sensor‚ locate the “Sensor” terminals on the STC-1000․ The sensor has two wires⁚ one for the positive (+) connection and one for the negative (-) connection․ Connect the positive wire of the sensor to the “+” terminal on the controller and the negative wire to the “-” terminal․ Ensure a secure connection to prevent any malfunctions or readings․

Connecting the Load

The STC-1000 has two separate relay outputs for controlling the load․ These outputs are typically labeled “Cool” and “Heat” or “Relay 1” and “Relay 2․” Connect the load to the appropriate relay output depending on your application․ For example‚ if you’re using the STC-1000 to control a heater‚ connect the heater to the “Heat” output․ If you’re using it to control a cooler‚ connect the cooler to the “Cool” output․ Ensure the load’s voltage and current rating are within the STC-1000’s capacity․

Powering the Controller

The STC-1000 can be powered by either AC or DC voltage․ The most common power supply options are AC 110V/220V‚ DC 12V‚ or DC 24V․ Ensure that the power supply you use matches the controller’s specifications․ The STC-1000 has a dedicated power input connector that typically accepts a standard two-pin plug․ Connect the power supply to the controller‚ and it will be ready for use․
