For laboratory equipment, diffusion furnaces, vacuum coating and single-zone high-stability heating loops.

For SiC elements, MoSi2 elements, resistance wire and far-infrared heating elements.

Single-phase heating control for injection molding, extrusion, drying and material heat-treatment equipment.

Which single-phase heating processes suit the ST200?

Vacuum coating, diffusion furnaces, industrial furnaces, drying and single-zone precision heating.

Can it drive SiC and MoSi2 elements?

Yes — select the control mode and current rating against cold/hot resistance change and the furnace process.

Can the panel be door-mounted?

Remote panel configurations are supported; interface and mounting conditions depend on the model.

Are constant voltage, current and power supported?

Yes, the corresponding closed-loop modes can be set per load and process target.

How much current margin should be reserved?

Base it on maximum operating current, inrush, continuous duty and cooling; our engineers will verify.
