Beckwith Electric M-2270B Adapter Panel

Adapts M‑2001 Series Digital Tapchanger Control s a General Replacement

for Transformer and Regulator Controls

• Provides mounting adaptable to several different configurations

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

Tapchanger Control is removed

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

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

• Optional SCAMPTM (SCADA Controlled Auto/Manual Pushbutton) replaces

AUTO/OFF/MANUAL toggle switch

• Optional 2 Level Local Voltage Reduction switch

• Optional 19" Rack Mount Adapter Panel Kit

The M‑2270B is an adapter panel which, when combined with the M‑2001

Series Digital Tapchanger Control, can be customized to fit as a replacement

for a variety of manufacturers’ LTC transformers and regulator controls.

Interface

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

of the adapter panel. The second terminal block provides access to auxiliary

functions, including self-test alarm, user-programmable alarm, auto disable

and manual raise/lower.

Features

Separate fuses for test terminal, voltage sensing and motor power are on

the front panel. Spare fuses for each are in the fuse holder.

Binding posts on the front panel allow easy connections for test procedures.

RAISE/OFF/LOWER, AUTO/OFF/MANUAL and VOLTAGE SOURCE switches,

DRAG HANDS RESET button, and NEUTRAL LIGHT are standard.

NEUTRAL LIGHT will light to indicate that the regulator is in the neutral position

when used with regulators which provide a circuit for this purpose.

Options

SCADA CUTOUT switch allows Local blocking of SCADA commands (for use with

SCADA enabled M-2001C controls). Use of the SCADA Cutout Switch with the

M-2001C, requires a M-2001C Control with firmware version D-0146V08.01.22

or later installed.

SCAMPTM (SCADA Controlled Auto/Manual Pushbutton) allows the Auto/Manual

state on the adapter panel to be changed by a SCADA command.

Use of the SCAMP pushbutton with the M-2001C, requires a M-2001C Control

with firmware version D-0146V08.05.XX or later installed.

Voltage Reduction switch allows 2 levels of Voltage Reduction to be selected.

19" Rack Mount Adapter Panel Kit (B‑1569) allows mounting the M‑2270B and

M‑2001 series control in a 19", 8U rack application.

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.

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.
