Blue Guard releases multiple TEC thermostats — meeting diverse temperature control needs in various scenarios.

TEC (Thermoelectric Cooler) semiconductor coolers achieve cooling or heating through the Peltier effect—requiring no compressor or refrigerant, only electricity. With their small size, low noise, and ease of integration, they have become an indispensable temperature control method for modern precision equipment. However, a TEC cooler alone is insufficient to meet requirements such as "precise temperature control, automatic start/stop, stable temperature control, and system protection." To address this issue, BlueGuard has launched a series of temperature controllers—using sensors, drive modules, and PID control algorithms to achieve real-time monitoring and precise temperature control. They also feature multiple safety mechanisms, including over-temperature protection, short-circuit protection, current overload protection, and sensor anomaly detection, comprehensively improving system reliability and stability.

Equipment Overview

The TEC TTD70xx series temperature controller is a highly integrated temperature control device that combines temperature acquisition and bidirectional DC temperature output. It can directly drive DC loads (such as TEC cooling coils), eliminating the need for external data acquisition units and solid-state relays. Based on real-time temperature data (PV) and the user-defined target temperature (SV), the controller intelligently calculates the PID control ratio and intelligently adjusts the output of cooling/heating power devices using PWM to achieve precise temperature control. Furthermore, the device is equipped with a 100Mbps high-speed network interface for easy connection to a host computer, supporting the standard Modbus TCP/RTU communication protocol to ensure efficient and compatible data transmission. The device features precise temperature control, high stability, strong anti-interference capabilities, and multi-level over-temperature protection. The system includes functions such as stopping output upon over-temperature alarm and shutting down output upon exceeding temperature limits, effectively protecting the safety of controlled items.
