The M-2299 is an adapter panel which, when combined with the M-2001 Series Digital Tapchanger
Control, provides convenient direct replacement of Toshiba TB-R800 regulators. The M-2299 mounts into
the control cabinet using the same two hinge pins which
must be saved
from the original regulator.
Interface
External connections are made via a wiring harness that connects from a fifteen-position terminal block to
the ”BT” terminal block on the existing control cabinet. An additional 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 and NEUTRAL LIGHT
are standard.
NEUTRAL LIGHT will light to indicate that the regulator is in the neutral position, for those regulators
equipped with 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 radi-
ated 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.
