Solutions with Power Backup

OH6425 series switchboards

The OH6425 series back-up switchgear is designed to install up to four 18-22 Ah batteries, providing a high level of energy independence in the event of a power failure. In situations where a higher backup capacity is required, the OH7525 Series can be used to accommodate up to four 36 Ah batteries.

The switchboards are tested to EN 61439-1 and are equipped as standard with a 230 VAC socket, circuit breaker, surge protector and tamper contact for unauthorised opening detection.

Optional accessories include thermostat, shock detection, optical box and safety lock, allowing the solution to be tailored to the specific requirements of the installation.

Choice of battery

It is always necessary to select the appropriate battery technology for the specific conditions in which the entire system will be operated. The right choice affects not only the lifetime and reliability of the backup, but also the overall safety and stability of the operation.

Monitoring

Monitoring is an essential part of the overall system. Thanks to backup power supplies with signalling, individual operating conditions such as 230 VAC failure, battery damage, low battery capacity or charging error can be distinguished very easily.

If maximum reliability is required, the system can be expanded with a BPM supply that converts the battery voltage to a stable 24 V. This is sufficient to power both the switch and the reliable transmission of data from the security systems, thus ensuring uninterrupted operation of the entire infrastructure.

PoE events

Switching off PoE in the event of a 230 VAC failure significantly extends the operating time on the battery. In situations where maintaining the functionality of the switch itself and the transmission of alarm buses is critical, this feature allows you to focus the available power on critical operations only, thereby increasing overall system reliability during a power outage.

Another possible scenario is to shut down PoE when the battery capacity drops below 30%. This ensures sufficient power reserve to operate the switch itself without a PoE load, while maintaining data transmission from the alarm system via the RS485 ports. This approach helps to extend critical operation time and increase overall system resilience in the event of a power failure.

For more complex scenarios, the IPLOG PLC can be used to enable intelligent power management in the system. Based on the 230 VAC outage time and the defined importance of each camera, it can gradually disconnect lower priority devices, optimizing power consumption and extending the uptime of key system components.
