Power supply module for fire protection systems EN54M 27.6V/10A/2x7-17Ah EN54M-10A7-17

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

This buffer power supply module, designed for fire protection systems, ensures the continued operation of alarm devices even in the event of a mains power failure. Compliance with EN54M standard guarantees its use in professional fire alarm systems. The device is dedicated to both installers and end-users who expect high reliability and safety.

Characteristics and application

The Pulsar EN54M-10A7-17 power supply module is an advanced solution for powering fire protection systems. It is designed to work with batteries with a capacity of 7Ah to 17Ah (two batteries in parallel). It provides a stable output voltage of 27.6V DC with a continuous current of 8.2A and a peak current of 10A for a short time (5 minutes), allowing the activation of devices requiring higher power consumption during an alarm. This ensures that the system remains operational even during short-term power outages.

The module's design allows for mounting on a DIN rail, which facilitates installation and integration with existing systems. Built-in protection against overload (OLP), short circuit (SCP), overvoltage (OVP) and undervoltage (UVP) protect both the module itself and the connected devices from damage. Additionally, it has EPS (AC power failure signal) and ALARM (failure signal) relay outputs. The EXTi input allows connection of external emergency signals.

Key features and benefits

• EN54-4 compliant: Guarantees compliance with requirements for fire alarm systems.
• High efficiency (88%): Minimizes energy losses and reduces operating costs.
• Wide input voltage range: Enables cooperation with various power sources.
• Built-in protections: Provide protection against damage and extend the life of the device.
• DIN rail mounting: Facilitates and speeds up installation.
• Relay outputs: Allow remote monitoring of power status and failure signaling.
• Designed for continuous and intermittent operation: Flexibility in application to different types of alarm devices.
• Compact dimensions (237 x 168 x 55 mm): Allow installation in limited space.
• 3-year manufacturer's warranty: Confirmation of high quality and reliability of the device.

Remember to mount the module in a suitable enclosure and perform additional tests to obtain a PN-EN54-4+A1+A2 or PN-EN12101-10+AC certificate – this is crucial for the correct operation of the entire fire protection system!
