The STX2410 is an EN54-4 approved power supply, ideal for use in fire control systems. Its regulated 27.6V DC output delivers up to 10 A continuous to the load while also supporting battery charging: 7.2 A load with 65Ah batteries, 10 A with 18Ah batteries, and 8 A with 38Ah batteries.
The output incorporates electronic short-circuit protection under both mains and standby battery operation. Maximum battery life is ensured through continuous active monitoring and a three-stage charger (bulk, absorb, and temperature-compensated float) that adjusts based on battery condition.
When fully charged, the unit operates in Eco power-saving mode, checking and topping up the battery every 2 hours without wasting energy on constant charging, thereby extending battery life. Deep discharge protection prevents premature battery failure during extended standby operation.
