WHD-RQ400-BY Digital Display Thermostatic Controller for Hot Melt Equipment

The WHD-RQ400-BY Digital Display Thermostatic Controller is designed for temperature control in hot melt pipe applications. It uses a digital display and three-button control system to make temperature settings and operating status easier to monitor.

The controller operates on AC 220V and is suitable for heating equipment rated from 400W to 1600W. It uses PID-controlled heating and high-precision thermocouples for temperature detection. The product also includes protection functions for overheating and short-circuit conditions, with an alarm if the temperature does not rise within the specified heating period or exceeds the set protection level.

For B2B buyers, digital thermostatic controllers should be evaluated according to heating power, temperature sensing method, control accuracy, protection requirements and compatibility with the final equipment. These factors are particularly important for manufacturers developing temperature-controlled heating and hot melt systems.
