Power control
Fields of application
Voltage stabilization (welding stations and machines, EDM machines), temperature control (film stretchers, electric ovens), dimming (photo studios, nurseries)
Features
The APR-D series is the successor to the αB and αC products. Their functions and performance have been greatly enhanced by the incorporation of a central unit, saving space, reducing wiring and lowering cost.
