2.b System Description
The MP2000E System provides backup power to traffic control signal equipment. It consists of
the MP2000E Battery Back-Up (BBS) System, the Power Transfer Switch (PTS), and batteries
that provide back up power when the line is unqualified. These three components can be
mounted inside an enclosure to provide protection from most weather conditions.
The traffic signal cabinet is powered continuously when a MP2000E system is installed. The
system allows connection for the normal utility power using standard terminal blocks or an
optional generator power via standard 30 Amp. (optional 50 Amp) generator receptacle. The
optional bypass switch redirects utility power to the load and allows the BBS to be removed
for service on a temporary or permanent basis without disrupting the operation of the traffic
signal.
With a fully functioning BBS system, the PTS allows utility power to flow out to the traffic
cabinet, when the utility line is qualified (within the acceptable range as programmed). If the
BBS is not functioning, the PTS will bypass the BBS allowing the utility to flow out to the
traffic cabinet. The BBS input is protected with one circuit breaker located on the PTS as well
as another one located on the BBS module. When the BBS internal BOOST and BUCK is
enabled, the PTS is activated allowing BBS to continuously boost the output when input is
lower, buck or lower the output when input is higher or run from batteries when input power is
outside the specified acceptable range. The PTS has dual NEMA power receptacles for
optional battery heating pads, connecting a vacuum cleaner, or a PC for maintenance.
The smart, temperature compensated internal charger continuously monitors and maintains
the batteries in a fully charged state. For the protection of the battery, the charging process is
