Power supply for fire protection systems EN54C 27.6V/5A/2x7Ah EN54C-5A7

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

This advanced buffered power supply, designed for fire alarm and smoke control systems, ensures uninterrupted power to critical devices. Designed in accordance with EN54-4 and EN12101-10 standards, it guarantees high reliability and safety of operation. It is ideal for both new and modernized facilities where protection against power failures is required.

Design and functionality

The power supply is characterized by a solid construction based on a DC01 steel housing with a thickness of 1mm, finished in RAL3001 (red) color. Inside there is space for two 7Ah/12V batteries (AGM or gel), which provides long-lasting backup power. Thanks to independent AUX1 and AUX2 outputs with a total current capacity of 5A, it is possible to connect various receivers without the risk of overload. A built-in microprocessor monitors the battery status, automatically compensating for temperature changes and performing regular efficiency tests. Additionally, the power supply has protections against short circuit (SCP), overload (OLP), overvoltage (OVP), undervoltage (UVP) and housing opening (tamper).

Key features and benefits

• Compliance with standards: Meets the requirements of EN54-4 and EN12101-10 standards, confirming its suitability for professional fire protection systems.
• Uninterruptible power supply: Automatically switches to battery power in the event of a mains power failure, ensuring continuous system operation.
• High efficiency: Efficiency at 87% minimizes energy losses and reduces operating costs.
• Advanced protections: Protects devices from damage caused by short circuits, overloads, overvoltages and tampering.
• Battery status monitoring: Automatic temperature compensation for charging and regular efficiency tests extend battery life and ensure their readiness for operation when needed.
• Optical signaling: Built-in LEDs indicate the status of the mains power supply, battery voltage and any failures.
• Easy installation: Designed for surface mounting, which facilitates installation and maintenance.
• Technical outputs: It has EPS (AC mains failure) and ALARM (collective failure) relay outputs to signal the system status.

The EN54C-5A7 power supply is an investment in the safety and reliability of fire protection systems – crucial for protecting life and property.
