KEHIPI

KEHIPI STC-3028 DC 12V HVAC Control with SHT20 Sensor

SKU CH-G8JB-SSE40

A DC 12 V thermostat controls heating and cooling with a waterproof SHT20 sensor measuring -20 °C to 80 °C and 0 % to 100 % RH, switching up to 10 A at 240 VAC

  • ColorDC 12V
  • DC 12 V supply powers the controller directly from vehicle or battery systems
  • SHT20 waterproof sensor measures temperature from -20 °C to +80 °C and humidity from 0 %RH to 100 %RH
  • Relay output handles 10 A at 240 V AC for switching heaters, fans or compressors
  • Gray ABS flame-retardant housing protects internal electronics in harsh environments
  • Separate start and stop temperature or humidity set-points give precise heating and cooling control

KEHIPI STC-3028 HVAC Controller

The KEHIPI STC-3028 is a DC 12V digital thermostat designed for HVAC regulation in automotive and tool applications. It suits installers needing a compact controller with an integrated SHT20 waterproof sensor for temperature and humidity monitoring.

Build Integration

The unit operates from a 12V DC supply and mounts in a grey ABS flame-retardant housing. Its relay output handles 10A at 240VAC, switching heating or cooling loads directly while the one-metre probe frees the main body for panel placement.

Sustained Load Behaviour

Under continuous operation the controller maintains set points across a -20°C to +80°C range and 0% to 100% RH span. Refrigeration delay protection and sensor-error alarms prevent short-cycling and alert operators to drift during extended duty cycles.

Highlights

  • DC 12 V supply powers the controller directly from vehicle or battery systems
  • SHT20 waterproof sensor measures temperature from -20 °C to +80 °C and humidity from 0 %RH to 100 %RH
  • Relay output handles 10 A at 240 V AC for switching heaters, fans or compressors
  • Gray ABS flame-retardant housing protects internal electronics in harsh environments
  • Separate start and stop temperature or humidity set-points give precise heating and cooling control

Questions about this item

What is the relay contact rating that limits continuous load on the STC-3028?

The relay output is rated for 10A at 240VAC, so the connected heater, fan or compressor must not draw more than 10 amps continuously.

How much heat does the controller itself generate during all-day operation?

The unit runs on a 12V supply and switches the load through its internal relay; the controller's own power draw is low, so self-heating is minimal inside the ABS flame-retardant housing.

What power source must already be present for the STC-3028 to operate?

A 12V DC supply is required to power the controller; the SHT20 waterproof sensor and relay output are included, so no separate sensor or contactor is needed.
