Power controller
Fields of application
Voltage stabilization (welding machines, electric discharge machines), heat regulators (film stretchers, electric ovens), lighting reduction (photo galleries, production plants).
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.
