STC 3028 Digital Temperature Controller What this product does and why it helps Dual display shows both current temperature and setpoint at a glance, making monitoring and adjustments fast and straightforward. Wide power compatibility (12V to 110–220V) lets you install the controller in different environments and electrical setups without extra converters. Precise control across the working range of 20°C to +80°C with ±1°C accuracy, supporting tasks that require consistent temperature regulation. Builtin relay output rated at 10A provides reliable switching of heaters or coolers and stable connections to connected equipment. Key attributes Model: STC 3028 Function: Digital temperature monitoring and control with setpoint adjustment Measurement range: 20°C to +80°C Accuracy: 1°C Output: Integrated relay, 10A capacity Power compatibility: 12V to 110–220V Benefits for customers Simplifies temperature management: clear displays and straightforward controls reduce setup time and make everyday adjustments easy. Fits varied installations: compatible power range accommodates batterypowered or mainspowered systems and different regional supplies. Improves reliability: a 10A relay and stable output reduce the risk of connection issues with heating/cooling devices. Provides reproducible results: ±1°C accuracy helps maintain consistent conditions for processes sensitive to temperature. Practical use scenarios Egg incubators or breeding chambers: maintain steady incubation temperatures in the 20–40°C range with clear setpoint monitoring. Home brewing and fermentation: control mash and fermentation temperatures up to 80°C to ensure reproducible results. Reptile terrariums, seed germination cabinets, and other controlledenvironment racks: use accurate temperature regulation and the 10A relay to drive heaters and thermostatic devices. What to expect in operation Visible realtime temperature plus setpoint on the dual display for quick verification. Straightforward wiring to compatible power sources in the 12V–110–220V range. A robust 10A relay output suitable for common heating elements and small cooling units within the controller's electrical limits. No technical specs have been altered: this description reflects the STC 3028 model, its 20°C to +80°C measurement range (±1°C), dual display, 12V–110–220V power compatibility, and integrated 10A relay output.
