★ Introduction：

FGRS-02A digital thermostat is a microprocessor based temperature control device that integrates a power junction box. It can provide antifreeze protection or temperature control required for process temperature maintenance for pipelines or storage tanks equipped with electric heat tracing systems. This product can be applied to constant power, mineral insulation, or self regulating forms of electric heat tracing, and can be installed for use in ordinary or hazardous explosion-proof environments.

★Features:

① Suitable for temperature control of single-phase power heaters and can be used in explosion-proof environments.

② PTC heaters, electric heat tracing belts, constant power heaters, and various heating controls can be applied.

③ It has the characteristics of touch operation, digital display, direct connection to high-power loads, and high temperature control accuracy.
