Product Details

The Pulsar EN54C-10A power supply and charger is a lightweight, high-efficiency unit, compliant and third-party tested to the latest version of EN 54-4 for use with Protec’s range of 24 Volt DC equipment.

The unit provides a 24 V (nominal) output from a 230 V mains input and automatically switches to a standby battery supply should the mains supply fail. Under normal conditions, the standby batteries are intelligently charged and monitored to ensure that, should they be needed, they are in optimal condition.
