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.
