Typical Applications
Multi-zone Heating Equipment
Six integrated single-phase channels for multi-zone kilns, ovens, mold heating and zoned heating on continuous lines.
Integrated Heating Control Cabinets
For cabinets concentrating multiple power loops, reducing component count and internal wiring.
Batch Equipment Integration
For OEM integration of similar multi-branch loops; per-channel capacity and load type checked individually.
FAQ
What does "6-channel" mean?
The unit integrates six single-phase power control loops for centralized control of independent heating branches.
Can each channel drive a different load?
Yes per configuration, but each channel’s rated current, load type and protection must be confirmed separately.
What is the advantage of 6-channel integration?
Fewer components and less wiring in the cabinet; still reserve ventilation, maintenance and terminal access.
Is it suitable for multi-zone kilns?
Yes for multi-zone electric heating; zone accuracy and temperature controller configuration follow the process.
How to configure fuses and breakers?
Size per channel rating, short-circuit protection requirements and product specifications — never replace per-loop protection with one master device.
