5AMP Power Supply Unit

The 5AMP PSU switch-mode power supply has been specifically designed for
EN54 compliant fire systems and EN12101 AOV systems.

Available in either 1A, 2A or 5A versions they are certified to EN54-4 and EN12101-10 by AFNOR and VdS (EN54-4 only).

The unit includes intelligent battery charging using Elmdene’s efficient EcoCharge
technology, possess mains & battery monitoring with 2x independent volt-free
outputs and also feature battery deep discharge protection in the event of a
prolonged mains failure.

The inclusion of LED indicators provides quick status diagnostics of the power
supply, while a variety of enclosures offer the installer a choice of standby battery
backup options.

Features

• 2 Independent 27.6Vdc monitored outputs


• The on-demand load-sharing capability supports either rapid charging of high-capacity batteries or brief high-current peak-loads
  using current diverted from a charger


• EN54-4 clause 6.4 compliant “Dual Path” power transmission option when the PSU is used with CIE but contained in a separate enclosure


• Charging capability (EN54-4 and EN12101-10 compliant) to support up to 65Ah batteries (see ‘Output’ table for maximum system load capability calculations)


• Battery-Free operation mode available (not EN54-4 compliant)


• Self-resetting battery fuse protection


• No output interruption during automatic switchover between mains and battery power


• Deep discharge protection disconnects the battery from the load when the output voltage falls below 21.6V


• Mains status indicator LED confirms mains input is present


• Battery status indicator LED confirms healthy battery


• Fault indicator LED (Yellow) active on detection of output fault, charger fault and mains failure


• Fault-diagnostic indicator LED assists with identifying the cause of the fault (visible through Lid)


• Output 1 and Output 2 status indicator LEDs (dual-path and independent mode option)


• Volt-free changeover (SPDT) relays transmit fault output signals
  (Comprising: loss of mains / battery fault /charger fault / loss of output)


• Optional RS485 serial interface for fault reporting, diagnostics and status indication and panel integration
