XH-W3001 DC 220V 1500W Digital Microcomputer Thermostat Switch

XH-W3001 DC 220V 1500W Digital Microcomputer Thermostat Switch is a robust digital controller designed for precise temperature management across various industrial and hobbyist applications. This module allows you to confidently switch heavy loads up to 1500W on a 220V AC or DC line, making it ideal for high-power heating and cooling systems. Consequently, the XH-W3001 provides accurate, automatic temperature cycling without requiring a separate control board. Furthermore, its direct power connection and simple programming structure streamline installation, enabling users to quickly set the desired start and stop temperatures for their equipment. Therefore, you can achieve superior control and energy efficiency in your projects by implementing this microcomputer switch.

Key Features:

• Microcomputer Control: An integrated digital microcomputer chip precisely processes temperature readings and manages the relay switching logic.
• High Power Capacity: The onboard relay manages maximum loads up to 1500W (10A) at 220V, empowering you to control most standard heating elements or compressors.
• High-Accuracy Sensing: This unit utilizes an NTC10K waterproof probe, ensuring fast response times and temperature measurements with ±0.1°C precision.
• Wide Control Range: The user sets temperature regulation between −50°C and +110°C, offering extensive flexibility for both freezing and heating environments.
• Direct Power Input: The controller works directly with 220V AC or DC power, simplifying the power supply circuit and minimizing external components.

• Control Accuracy (Hysteresis): 0.1°C to 30°C (User adjustable)
• Measurement Input: NTC10K Waterproof Probe (1 meter length)
• Display Type: Three-digit LED (Moreover, the LED colors often indicate status: Red for temperature, Green for status).
• Operating Environment: −25°C to +55°C, Humidity 20%–85% (Non-condensing)

Mechanical Specifications:

• Shell Material: Durable ABS Flame Retardant Plastic
• Installation Type: Embedded Panel Mount (requires a cutout)
• Relay Type: Single Pole Single Throw (SPST)
• Button Type: Tactile switches for setting “Start” and “Stop” temperatures.

Dimensions:

• Body Size: ≈ 60 mm x 45 mm x 31 mm
• Mounting Hole Distance: ≈ 73 mm
• Panel Cutout Size: ≈ 42 mm x 26 mm
• Wire Length: Standard unit includes a 1-meter NTC sensor cable and mounting wires.

Pinout and Wiring:

• Input Terminals (Red/Black Wires): Connect these terminals directly to your 220V power source (AC Line and Neutral or DC positive and negative).
• Output Terminals (Yellow/Black Wires): These terminals represent the relay contacts. You must connect them in series with the load you want to control.
• Wiring Logic: The controller effectively interrupts or completes the circuit to the load based on the programmed temperature settings.
• Safety Warning: Crucially, always de-energize the circuit before making or changing any wiring connections due to the high operating voltage.
