27.6 Vdc Switch Mode Power Supply for Fire – EN54-4:1997 +A1 +A2

STX2410-E Optional BATT-BOX-65 STX2410-H

EATURES

The STX2410-x is an EN54-4:1997 +A1 +A2 approved power supply ideal for use in Fire control Systems. Its regulated 27.6V dc output will supply a total of 10 Amps continuous into the load, whilst also enabling battery charging. (7.2 Amps Load with 65Ah batteries, 10 Amps with 18Ah batteries).The power supply output features electronic short circuit protection under both mains and standby battery operation. Maximum battery life is assured through continuous active battery monitoring and the use of a three stage charger, comprising bulk, absorb and temperature compensated final float phase depending upon battery condition. Once fully charged the product operates in Eco power saving mode, whereby the batteries are charged for 4 hours in every 24 hour period while still being continuously monitored. This reduces wasted energy in charging already fully charged batteries and extends their working life. Deep discharge protection prevents premature battery failure when operating from standby for extended periods. Two sets of volt free solid state relay fault output signal (i) loss of mains and (ii) battery fault, charger fault and loss of output. In addition there is an RS232 serial interface that can provide diagnostic and fault reporting information to supervisory systems.

• Certified by UL to EN54-4:1997 +A1 +A2.

• Up to 10 A current to load at 27.6V dc nominal regulated output.

• Charging capability to support 18, 38 or 65Ah batteries with intelligent load enhancement.

• Electronic overload protection shuts down output until overload or short circuit is removed.

• Battery Monitor detects battery missing, low battery, short-circuit or reverse connection or

circuit impedance (Ri) in excess of 300mΩ caused by connector or wiring corrosion within 4hours..

• Battery charging circuit is energised only when a battery is correctly connected and the battery

voltage is greater than 14 V.

• No loss of output during automatic connection of battery to load on loss of mains.

• Deep discharge protection disconnects battery from load when battery voltage falls to 21 V.

• Fault indicator LED (Yellow) flashes on detection of output fault, battery fault, charger fault and

mains failure.
