Power supply for fire protection systems EN54C 27.6V/5A/2x40Ah EN54C-5A40

Power supply for fire protection systems – reliable power in crisis situations

This buffer power supply, designed for fire protection systems, provides uninterrupted power to devices requiring stabilized 24V DC voltage. This is crucial for the proper operation of fire alarm systems, smoke and heat control, and fire automation. The device automatically switches to battery power in the event of a mains voltage failure, guaranteeing the continuity of safety systems.

The power supply has been designed for ease of integration and use. It has two independently protected AUX1 and AUX2 outputs, delivering a current of 5A at a voltage of 27.6V DC. The ability to cooperate with EN54C-LB4 and EN54C-LB8 fuse modules (available separately) allows you to expand the system with additional protection for individual circuits. Additionally, optional EN54C-LS4 and EN54C-LS8 sequential modules allow you to control the operation of actuators in fire dampers and ventilation flaps.

Key features and application

• Compliance with standards: Meets the requirements of EN54-4 and EN12101-10 standards, guaranteeing its suitability for professional fire protection installations. It has a CNBOP-PIB No. 1438-CPR-0628 certificate of conformity and a CNBOP-PIB No. 5222/2024 approval certificate.
• High efficiency: Efficiency at 87% translates to minimal energy losses and efficient resource utilization.
• Versatility: Designed to work with AGM or gel lead-acid batteries, providing flexibility in component selection. Recommended batteries are 2x 40Ah/12V.
• Safety: Short-circuit (SCP), overload (OLP), overvoltage (OVP), undervoltage (UVP) and tamper protection ensure the protection of the device and system.
• Monitoring and remote control: The ability to connect an RS485 or Ethernet communication interface allows for remote monitoring of power supply parameters and system diagnostics.
• Durable construction: The housing made of 1.2mm thick DC01 steel sheet, painted red (RAL 3001), ensures durability and resistance to mechanical damage. IP30 protection class protects against access to internal elements.
• Signaling: The LED panel informs about the operating status of the device, and the EPS and ALARM outputs signal AC network failures and general problems in the system.

The power supply is an ideal solution for both professional fire protection installers and end-users looking for a reliable emergency power source for their safety systems. Surface mounting simplifies installation, and the lock secures the housing against unauthorized access. The device has a three-year manufacturer's warranty – Pulsar K. Bogusz Sp. j.. The battery charging current is 1.8A and the current consumption by the power supply circuits is a maximum of 55mA. The housing dimensions are 420 x 407 x 178 mm (+/-2 mm) plus an additional 8mm distance from the ground.
