Beckwith Electric M-2067B Adapter Panel

Adapts M‑2001 Series Digital Tapchanger Control to Replace Westinghouse

SVC and SVR Controls and Beckwith Electric M‑0067 Tapchanger Controls,

or as a General Purpose LTC Transformer Control

• Connects easily to the M‑2001 Series Digital Tapchanger Control using

four mounting screws and 24‑pin connector

• Provides mounting adaptable to several different configurations

• Provides built‑in CT shorting protection when the M‑2001 Series

Tapchanger Control is removed

The M‑2067B is an adapter panel which, when combined with the M‑2001

Series Digital Tapchanger Control, provides convenient direct replacement

for Westinghouse SVC and SVR controls and Beckwith Electric M‑0067

series controls. The M‑2067B can also be used, with the M‑2001 Series

Tapchanger Control, as a general purpose LTC transformer control.

The M‑2067B permits changing of the M‑2001 control without adapter panel

removal or rewiring.

Interface

External connections are made to two terminal blocks located on the rear of

the adapter panel. The second terminal block provides auxiliary functions,

including self‑test alarm, user‑programmable alarm, manual raise/ lower,

operations counter and ∆VAr 2 disable.

Testing Specifications

High Voltage: All input and output terminals will withstand 1500 Vac rms to

chassis or instrument ground for one minute with a leakage current not to

exceed 25 mA, for all terminals to ground. Input and output circuits are

electrically isolated from each other, from other circuits and from ground.

Surge Withstand Capability: All input and output circuits are protected

against system transients. Units pass all requirements of ANSI/IEEE

C.37.90.1-1989 defining surge withstand capability.

Radiated Electromagnetic Withstand Capability: All units are protected

against electromagnetic radiated interference from portable communications

transceivers.

Control Accuracy Specification: All units comply with ANSI/IEEE C57.15-1986

defining control accuracy of operation.

Environmental

Temperature Range: Functionality is maintained from ‑40° to +85° C.

Humidity: Functionality is maintained under 95% relative humidity (non‑condensing).

Fungus Resistance: A conformal printed circuit board coating inhibits fungus growth.
