Main Panel Power Supplies
EST3 Power supplies consist of two assemblies, a high efficiency switch mode power
supply card and a power supply monitor module. Up to four power supplies may be
combined in a single enclosure to provide up to 28 amps of available current.
Battery backup is provided using from one to four sets of batteries, depending on
standby power requirements to support up to 260 AH batteries
The power supply comes in two styles: a primary supply and a booster supply.
Each power supply produces 7 amps of filtered and regulated 24 VDC. The primary
power supply provides the system with battery charging and voltage regulation.
The booster supplies work in
concert with the primary
supply are available with or without battery charging capa-
bility. Software configuration configures the battery changing
circuits for either 10-24 AH batteries or 30 – 65 AH batteries and
controls the high/low charge rate.
EST3 power supplies individually monitor batteries for load de-
ficiencies, short circuits, and insufficient voltage levels and re-
port trouble back to the 3-CPU3. The 3-LCD displays any trou-
bles and the power supply’s address, a specific trouble code,
and a text message describing the specific trouble.

Battery Distribution Unit
The 3-BTSEN consists of a circuit breaker and copper bus bars mounted on a sheet metal
bracket. The unit provides a backup battery bus for supplying backup power to multiple
power supplies fed by a common battery. The 3-BTSEN features a 50 Amp circuit breaker
to protect the backup battery. The 3-BTSEN mounts in the BC-1 Battery cabinet or any
EST3 “RCC” series enclosure.
