M-2001D

M-2001D Digital Tapchanger Control for Transformers and Regulators

Beckwith’s Tapchanger Control line uses an innovative concept in new transformer or regulator applications or control replacements by using a universal tapchanger control – the M-2001 – with interchangeable adapter panels. The replacement panels are sized to correspond to the original manufacturer’s controls, use the same mountings, and include wire harnesses that match the existing connections – all for easy replacements. The M-2001’s easy installation, its comprehensive communication capabilities and its variety of features that meet all types of applications have made this control very popular in the industry.
