Power supply module for fire protection systems EN54M 27.6V/3A/2×17-40Ah EN54M-3A17-40

Fire Alarm System Power Supply Module – Reliable Power in Critical Situations

This power supply module, designed for fire alarm systems, ensures the continuous operation of devices responsible for safety. The buffered power supply stabilizes the voltage at 27.6 V DC, guaranteeing the correct operation of detectors, alarms and other system components. The device's design takes into account the requirements of EN54-4 and EN12101-10 standards, confirming its compliance with the highest safety standards.

The power supply is an ideal solution for both installers of fire alarm systems and end-users looking for a reliable power source for their systems. Thanks to its compact dimensions (200 x 120 x 48 mm), the module easily integrates with existing infrastructure. High efficiency (89%) translates to minimal energy losses and reduced operating costs.

• Protections: SCP (short-circuit protection), OLP (overload protection), OVP (overvoltage protection), UVP (undervoltage protection) – comprehensive protection of the device and connected elements.
• AUX1 and AUX2 outputs: Two independently protected outputs provide flexibility in connecting various devices.
• Battery charging current: 1.8A – optimal charging of batteries with a capacity of 17Ah to 40Ah, ensuring long-term system operation in the event of a mains power failure.
• Power supply circuit current consumption: Maximum 52mA – low standby current consumption minimizes energy losses.
• Mounting: Possibility of mounting on a DIN rail (EN54M-DIN1 bracket required) or built-in – adaptation to different installation conditions.

This module is compatible with batteries with a capacity of 17Ah to 40Ah, allowing it to be adapted to the specific needs of a given fire alarm system. Designed for continuous and temporary operation (Imax b - 5 minutes), ensuring reliability in emergency situations. The manufacturer's warranty is 3 years, which demonstrates the high quality and durability of the product. It is worth remembering that in order to install the module in a fire alarm system, it must be placed in a suitable housing and undergo additional tests to obtain a certificate of conformity with PN-EN54-4+A1+A2 or PN-EN12101-10+AC standards.
