27.6V dc 10A Switch Mode Power Supply for Fire, Access and General Applications
STX2410-MOD
F
EATURES
The STX2410-MOD is an un-boxed switch mode power supply ideal for use in Fire, Access Control and
General Applications. 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 outputs 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.
•
Up to 10A 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, reverse connection or circuit
impedance (Ri) in excess of 300m
caused by connector or wiring corrosion.
•
Battery charging circuit is energised only when a battery is correctly connected and the battery
voltage is greater than 14V.
•
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 21V.
•
Fault indicator LED (Yellow) flashes on detection of output fault, battery fault, charger fault and
mains failure.
•
Mains indicator LED (Green) showing mains present.
•
RS232 serial interface for fault reporting and diagnostics interface to OEM equipment.
