Dycon EN54-4 Certified 24VDC 1.5A, 3A or 5A Power Supply

Summary

Dycon D2431, D2433 and D2435 units are 1.5 Ampere, 3 Ampere and 5 Ampere switched-mode power supplies complying with and certified to EN54-4 and the Construction Product Regulations (CPR). 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.

Not all EN54-4 Power Supplies are the same!

Dycon’s EN54 has unique features that improve performance and reliability

A fire alarm system power supply needs to be robust to ensure the safe continuity of fire detection. Dycon’s EN54 range has additional performance features built-in that most other makes fail to provide. These will ensure that not only does the unit provide reliable power when needed, but also so continuously monitors total performance, even regularly checking batteries’ performance to ensure that it will operate correctly even if the mains power is lost.

Main Features

The Dycon EN54-4 range consists of 5 Amp, 3 Amp and 1.5 Amp devices, providing a nominal 27VDC with two separate 12V lead-acid batteries for standby operation when AC power is lost.
