Description
Elmdene 24Vdc 8A + 1.6A Switch Mode PSU EN54 Approved (2 x 38Ah Batteries)
The STX2410 is an EN54-4 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 & 8A with 38Ah 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 it will check and top up battery charge every 2 hours, but will not waste energy by continuously attempting to charge a fully charged battery. This also extends the operating life of the battery. Deep discharge protection prevents premature battery failure when operating from standby for extended periods.
