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