STC-3028 12V Digital Temperature Humidity Controller

Dual Temperature & Humidity Control: Integrated dual relay outputs allow simultaneous automated management of both heating/cooling equipment and humidification/dehumidification systems.

12V DC Low-Voltage Operation: Powered directly by a 12V DC power source, making it ideal for automotive applications, battery banks, off-grid solar, and campervans.

Dual High-Brightness Digital Display: Dual LED screen provides real-time, side-by-side telemetry for ambient temperature and relative humidity (RH).

Included High-Precision Combo Sensor: Bundled with an integrated temperature and humidity sensor probe for precise thermal and moisture sensing in air and microclimates.

Programmable Climate Parameters: Features configurable hysteresis differentials, delay start protection, high/low limit alarms, and independent sensor calibration.

Housing Material: Flame-retardant ABS plastic panel-mount housing with side mounting clips and protective terminal covers.

Technical Specifications:

Input Voltage: 12V DC.

Temperature Range: -20°C – +80°C.

Humidity Range: 0% – 100% RH.

Relay Output Rating: 10A / 220VAC or 10A / 12VDC (per channel).

Housing Color: Grey / Black Casing with Red/Blue LED Displays.

Usage Advice: Verify 12V DC power input polarity before energizing; ensure load terminal screws are tightened securely to prevent voltage drop or heat buildup.

Maintenance: Keep the combo sensor housing free from heavy dust, moisture condensation, or oily residue to maintain accurate sensor readings

Essential 12V Climate Control Hub: Position as an all-in-one environmental controller for 12V egg incubators, campervan climate systems, mushroom cultivation, greenhouses, and reptile terrariums.

Highlight Combined Environmental Control: Emphasize how a single 12V unit manages both temperature (heater/fan) and humidity (humidifier/dehumidifier) simultaneously without requiring separate controllers.

Recommended Cross-Sell Add-ons: Pair with STC-3028 24V Digital Temperature Humidity Controller, STC-3028 220AC Digital Temperature Humidity Controller, STC-3008 12V Thermostat Dual Temperature Controller, and ESD antistatic mat 50x40CM PCB Welding Mat.
