The connectPower BBU combines with our power supplies and a customer supplied battery pack to form a scalable UPS system. This enables you to put together a UPS system uniquely tailored to your application.

This full featured unit has all the diagnostics needed for



applications where it is critical to know the status of the power system.

BBU - Battery Backed-Up Power Supply

BBU Operation (12/24V):

Diagnostic LEDs, control inputs and relay outputs

“Battery Low” LED (yellow):

“Charging” LED (yellow):

“Fault” LED (red):

“Drain” input

“Enable” input

On when battery voltage is 14.75 / 29.5V or greater.

“Bat Status” relay is energized.

Once fully charged the BBU drops the charge voltage to

13.65 / 27.3V (“float” voltage).

On when battery voltage is <11 / 22Vdc.

“Bat Status” relay is de-energized.

If the battery voltage drops below 9.7 / 18.7V the load is switched off.

On when BBU is charging the batteries.

Off when the “Full Charge” LED is on.

On when AC fails.

On when external power supply voltage is <11 / 21.5V.

On when batteries not connected.

On when battery voltage is <9.7 / 18.7V

Fault relay de-energizes for the above conditions.

Batteries connected in reverse.

Fault relay de-energizes and fault LED turns on.

Internal fuse opens to prevent damage to BBU or batteries.

No batteries connected - takes approx. 60 seconds to detect after turning on BBU.

“Fault” LED is on and Fault relay is de-energized.

A temporary short between the “Drain” and “COM” terminals switches the load

to the batteries until the battery voltage reaches 11 / 22V. At this point the AC

power is returned to the power supply and the BBU starts recharging the batteries.

A temporary short between the “Drain Reset” and “COM” terminals disables

the Drain cycle to the batteries.

A connection between the “Enable” and “COM” terminals enables the BBU.

If terminals are open circuit (Disabled) the BBU functions as a battery charger

only. In the event of AC failure the batteries are not connected to the load

via the BBU. The BBU is factory preset as Enabled.
