2405STE Intelligent Switch Mode Power Supply: EN54-4 Certified
27.6Vdc 5A PSU with Intelligent Battery Charging, Monitoring and Remote Fault Signalling
O
VERVIEW
The 2405STE is a fully featured EN54-4 approved power supply ideal for use in Fire Systems and Access control applications. Its regulated
27.6V dc output will supply up to 5A continuous into the load, in addition to providing up to 1.6A for charging the standby 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. Deep discharge protection prevents premature battery failure when
operating from standby for extended periods. Two sets of volt free solid state relay fault output signal (i) loss of mains and (ii) battery fault,
charger fault and loss of output.
Certified by VdS to EN54-4:1997 +A1: 2002 + A2: 2006
