Elmdene 2402STE Bedienungsanleitung

2402STE Intelligent Switch Mode Power Supply: EN54-4 Certified
27.6Vdc 2A PSU with Intelligent Battery Charging, Monitoring and Remote Fault Signalling
Overview
The 2402STE 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 2A continuous into the load, in addition to providing up to 0.8A 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

2A current to load at 27.6V dc nominal regulated output

Electronic overload protection shuts down output until overload or short circuit is removed

Battery Monitor detects battery missing, low battery, short-circuit or reverse connection

Battery charging circuit is energised only when a battery is correctly connected and the battery voltage is greater than 14V

No loss of output during automatic connection of battery to load on loss of mains

Deep discharge protection disconnects battery from load when battery voltage falls to 21V

Automatic start-up on battery only

Fault indicator LED (Red) flashes on detection of output fault, battery fault, charger fault and mains failure

Mains indicator LED (green) showing mains present
