The new STV range of switch mode power supplies has been specifically designed for EN54 compliant fire systems and is NFS Approved.

Available in either 1A, 2A or 5A versions they are certified to EN54-4, EN12101-10 and NF S 61-940 by AFNOR and VdS (EN54-4 only).

The units include 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 Independant 27.6Vdc monitored outputs
• On-demand load-sharing capability supports either rapid charging of high-capacity batteries or brief high-current peak-loads using current diverted from 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 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 battery from load when 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 cause of 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
• Supplied with Power Sonic VRLA batteries or without
