Dycon D2435-17 | EN54-4 Approved 5Ah Power Supply (max 17ah battery)
INC VAT
Code: FDS401/554
A premium range of fire alarm remote power supply units, the Dycon D2435-17 is a 5amp switched-mode power supply complying with EN54-2 and EN54-4.
The PSU features on demand load sharing to provide exceptional flexibility, allowing rapid, large-capacity, battery charging with either extended, standby, hold-up duration at light loads, or short, high current, peak loads where the spare capacity is diverted to battery charging.
All units are fitted with a constant operation temperature sensor which automatically adjusts the charging rate to ensure that a battery is never over charged simply because the ambient temperature has risen.
Rather than relying on simple, voltage readings to gauge the battery condition, the D243X-series units constantly check the batteries impedance which gives a more accurate reading and prior warning of impending problems.
Microprocessor controlled operation and protection
On-demand battery charging and load output current sharing
Battery impedance monitoring
Automatic output reconnection after short circuit fault
No user-serviceable fuses, outputs protected by electronic E-fuses
Two independent, electronically fused, switched outputs
Three opto-relay fault outputs for AC Power Fail, Battery Fault, PSU Fault
Four status LED’s; I x external and visible, 3 x inside the housing, visible on removing the lid
Over-voltage output protection
Battery-free option can be selected by a jumper. Note : Using this jumper to disable the battery monitoring when a battery is fitted will create an EN54-4 non-compliance.
On-board or remote temperature sensing (jumper selectable) with optional remote sensor
UK-manufactured electronics and steel housings
