W3230 Digital Temperature Controller AC100V-220V

W3230 Digital Temperature Controller is a robust and highly reliable device that provides precise control over heating and cooling systems. Designed for universal compatibility, this version operates directly from an AC 100V-220V power supply, eliminating the need for an external transformer and simplifying installation significantly. It features a bright LED display, allowing users to easily monitor the current temperature and configure the target settings. Equipped with an accurate NTC sensor and a powerful 10A relay, the W3230 effectively maintains a stable temperature within a user-defined range, making it the perfect tool for critical applications that demand consistent thermal management. You can quickly switch between heating and cooling modes to automatically manage any enclosure or environment.

Key Features:

• Wide AC Voltage Input: Directly accepts AC 100V to 220V power, offering flexible use in various household and industrial electrical systems.
• Heating and Cooling Modes: Automatically toggles between heating (H) and cooling (C) modes, allowing the controller to manage the temperature actively, preventing both under and overshoot.
• High-Current 10A Relay: The robust output relay can directly switch high-power loads, such as heaters, fans, or solenoids, up to 10 Amps at 220V.
• High-Precision Sensing: Utilizes a waterproof NTC 10K 3950 sensor, which provides accurate temperature measurement over a wide range.
• Digital Display and Configuration: A clear three-digit LED displays the current temperature, and a simple three-button interface facilitates quick setting of parameters like target temperature and hysteresis.
• Data Storage: The device retains all settings even after power loss, ensuring continuous, reliable operation.

Pinout and Wiring:

• Power Input (AC L / AC N): Connect the live (L) and neutral (N) wires of the 100V-220V AC supply here.
• Load Output (K0 / K1): These are the contacts of the internal 10A relay. Connect the load (e.g., a heater or fan) between one of these terminals and the AC power line. Note: The relay acts as a simple switch, you must wire the load in series with the AC source.
• Sensor Input: Connect the two wires from the NTC temperature probe here. The sensor wires are non-polarized.
• Wiring Note: Always disconnect the main power supply before making any connections. Ensure all high-voltage connections are secure in the screw terminals to prevent shorts or arcing.

Commonly Used in:

• Incubators and Terrariums: Maintain precise environmental conditions for hatching or reptile habitats.
• Home Brewing: Control fermentation temperatures to ensure consistent quality in beer or wine making.
• Refrigeration: Used as a primary or backup controller for freezers, chillers, and cold storage units.

Applications:

• Heating/Cooling Control: Manage the temperature in small rooms, cabinets, or specialized enclosures.
• Exhaust Fan Automation: Automatically activate cooling fans when a threshold temperature is reached in server racks or electrical panels.
• Simple PID Systems: While not a true PID controller, its heating/cooling logic and adjustable hysteresis can manage basic, non-critical thermal processes effectively.

Equivalent Models:

• XH-W1209: A lower-cost, simpler version often requiring a 12V DC power supply.
• STC-1000: A long-standing industry standard for AC-powered heating and cooling control, typically featuring dual relays for dedicated H/C outputs.
