With a built-in power device capable of managing up to 25A at voltages up to 440V AC, the STOM1 offers exceptional reliability and versatility.

This compact module provides two selectable power control modes—phase-angle and burst-firing—allowing for optimal energy management in various scenarios. The STOM1 features a soft-start function in phase-angle mode, automatically switching to burst-firing mode when the control signal reaches a preset threshold. This automatic transition ensures consistent performance even if the input signal fluctuates.

Additionally, the controller includes a ramp-up feature, adjustable from 0 to 30 seconds, making it ideal for applications that require gradual heating. With fully isolated input signals (0-5V DC or 4-20mA), the STOM1 can be seamlessly integrated with temperature controllers, PLCs, or PCs, offering unparalleled flexibility for equipment designers. Its robust construction and simple wiring make it suitable for various resistive loads, including ovens, moulders, and dryers.

The STOM1 is particularly effective for managing heating loads with low cold resistance, ensuring energy efficiency and prolonged equipment life. Key Features: Energy-Saving Design Soft-Start Functionality Selectable Phase-Angle or Burst-Firing Modes Simple, Efficient Wiring Standard 80mm Fixing Solid-State Reliability Isolated Input Signals Rugged and Compact Construction Integrated Power Device Applications: The STOM1 is ideal for controlling resistive loads in industrial settings, including: Ovens Moulders Dryers Any unusual heating loads with low cold resistance Suitable for most resistive loads including ovens, moulders, and dryers with current ratings up to 25A when fitted onto a suitable heatsink (1.3°C/W). Ideal for unusual heating loads which have very low resistance when cold.
