Beckwith Electric M-2278 Adapter Panel

The Beckwith Electric M-2148 Adapter Panel, used in conjunction

with the M-2001 series Tapchanger Control, uses modern electronic

digital design and digital processing circuitry to achieve an overall

stability and resolution unattainable with electromechanical and

analog design tapchanger controls. CMOS semiconductors are used

throughout the design. The M-2148 Adapter Panel, with the M-2001

series Tapchanger Control, provides a solid state voltage control relay

designed to directly replace the General Electric LRT 48 control.

There are several sizes of LRT 48 controls, therefore, verify that the

M-2148 is the correct replacement.

The combination of the Tapchanger Control and Adapter Panel includes

the following features:M-2148-P: Replaces General Electric LRT-48

Controls and includes the M-0115A and M-0127A for paralleling.

(M-0329B is not available)M-2148-B: Replaces General Electric

LRT-48 Controls and includes the M-0329B for LTC Backup Control

Protection.

The M‑2069 Adapter Panel, when combined with the M‑2001C or M-2001D

Digital Tapchanger Control, offers convenient, direct replacement of

Westinghouse SVC or SVR controls and Beckwith Electric M‑0067E controls

or M-2067B adapter panels.

The M‑2069-M-2001D combination can also be used as a general purpose

LTC transformer control.

The M‑2069 enables changing of the M‑2001 control without adapter panel

removal or rewiring.

• 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

• SCADA Cutout (Local/Remote) switch allows Local Blocking of SCADA commands

(for use with SCADA enabled M-2001C and D controls)

• Convenient Auto/Off/Manual and Raise/Lower Switches for toggling between

Automatic mode and Manual (local) mode to adjust the tapchanger position from

the front panel The M‑2069 is an adapter panel which, when combined with the

M‑2001C or M‑2001D Digital Tapchanger Control, provides convenient direct

replacement for Westinghouse SVC and SVR controls and Beckwith Electric

M‑0067E controls.

The M‑2069 can also be used, with the M‑2001 Series Tapchanger Control,

as a general purpose LTC transformer control. The M‑2069 permits changing

of the M‑2001 control without adapter panel removal or rewiring.

The Beckwith Electric M-6283A Three Phase Digital Capacitor Bank Control is a

three phase sensing and ganged or optional independent phase operation

complete solution designed for remote capacitor automation, monitoring,

and protection for high voltage utility distribution systems.
