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.
- Connects easily to the M-2001 Series Digital Tapchanger Control using
mounting screws and 24-pin connector
- Provides mounting adaptable to several different configurations
- Provides built-in CT shorting protection when the M-2001 Series Digital
Tapchanger Control is removed
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.
Testing Specifications
High Voltage: All input and output terminals will withstand 1500 V ac
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.
