Power supply module only 24 volt 3 Ampere. Power supply module only 24 volt 3 Ampere. Dycon D2435 switched-mode power supply providing up to 3 Ampere and complies with and certified to EN54-4 and the Construction Product Regulations (CPR) WHEN FITTED WITHIN OUR DYCON EN54-4 HOUSING. They feature 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 overcharged simply because the ambient temperature has risen. Rather than relying on simple, voltage readings to gauge the battery condition, these units constantly check the batteries’ impedance which gives a more accurate reading and prior warning of impending problems and extending battery life. This EN54-4 24 (27.6) VDC 3 Amp PSU module can be fitted with 2 x 7 Ahr, 2 x 17 Ahr or 2 x26 Ahr batteries. Supplied with T1 spade connector battery cables. The unit has 3 opto relay fault outputs, 2 x 24 VDC electronically fused outputs and 2 control inputs to switch the outputs.
