The STX2410-MOD is an EN54-4:1997 +A1 +A2 approved power supply, ideal for use in fire, smoke, and ventilation control systems. Its regulated 27.6V DC output supplies up to 2 A continuous to the load and provides up to 700 mA for charging standby batteries up to 18 Ah.
The output features electronic short-circuit protection under both mains and standby battery operation. Maximum battery life is ensured through continuous active monitoring and a two-stage charger (bulk and temperature-compensated float) that adapts to battery condition.
Once fully charged, the unit operates in Eco power-saving mode, charging the batteries for only 4 hours in every 24-hour period while continuously monitoring their status. This reduces unnecessary energy use and extends battery life. Deep discharge protection prevents premature battery failure during extended standby operation.
The STX2410-MOD provides two sets of volt-free solid-state relay fault outputs:
Loss of mains
Battery fault, charger fault, or loss of output
An optional plug-in serial interface allows diagnostic and fault reporting to supervisory systems.
