Beckwith M-0280 M-0270 Tapchanger Controller Module

Beckwith Electric’s M-0280 Tapchanger Controller Module is a solid-state voltage control relay designed to drive tap-changing transformers and regulators, forming part of Beckwith’s M-0270/M-0278/M-0280 family of tapchanger controls. It provides true RMS voltage sensing, delivering accurate tap decisions even when the input voltage and current contain distortion. Built for harsh environments, the module uses high-precision components that exceed ANSI/IEEE C57.15-1986 Class 1 accuracy over a temperature range of -40 °C to +80 °C. Input and output circuits are protected against system transients to guard against mis-taps and equipment stress. These features reflect Beckwith’s approach to reliable, automated voltage regulation in substation and industrial power system applications.
