  • Use basic catalogue number, e.g. CBU4
  • Add either suffix /48, /110 or /220 for 48, 110 or 220VAC output Voltage
  • Add suffix /3 for standard 3 hour duration (systems for 1 hour duration can be manufactured to order, add suffix /1)
  • Example ordering code is now CBU4/110/3 (4kW 110V central battery system for 3 hours duration)

Specification / Technical Information

REMOTE MONITORING/CONNECTIONS
Volt-Free Contacts

Includes Volt-free contacts for system in battery mode, charger fault, load alarm and common alarm. Normally open and normally closed contacts are provided for each of the above alarms. Alarm relays are energised when in healthy condition and relax into the fault condition. This ensures the contacts indicate a fault condition even when the system is off or in sleep mode (no power for extended periods).

SYSTEM OPERATION
Mains Healthy

The battery charger charges the batteries and the load is supplied via the isolation transformer and changeover. For non-maintained applications, the output is normally off and therefore the isolation transformer is not required.
Mains Failure
The load is transferred to the battery which will supply the load for the rated duration (usually one or three hours) or until the mains power is restored. Systems are generally supplied with single phase input but three phase input can be supplied if required. Three phase input systems utilise one phase from the input to supply any maintained load (via the changeover).

PROTECTIONS
Overload Protection
During mains healthy conditions overall load is monitored, overload is displayed and the buzzer sounds if the rated load is exceeded for more than 5 seconds. During mains failure, overload is displayed and the buzzer sounds if the preset overload point (>120% of rated load) is exceeded for more than 5 seconds.
Battery Disconnection Protection
Battery connection is monitored to ensure continuity and if disconnected the display will indicate that the battery is off and the buzzer will sound.
Deep Discharge Protection
During prolonged mains failures, the system will deplete the battery to protect the battery from further discharge. The discharge current is reduced to virtually zero by the system inducing sleep mode.
Reverse Battery Polarity Protection
The system is protected from reverse battery protection as required by BS EN 50171.
