The freely programmable REG-DPA regulator is used in medium and high-voltage networks to regulate continuous, variable-under-load arc suppression coils (Petersen coils, also known as P-coils or E-coils). In addition, they can handle all other control, measurement and regulation tasks having to do with petersen coils. The IP54-class device is available for wall mounting, insertion in a control cabinet or in a housing designed for rail assembly.
