Phoenix Contact akumulátor 15A 1,2Ah 24V vyrovnávací modul 1274520

This buffer module uses double-layer capacitor technology to bridge brief power interruptions and voltage dips in 24 V DC circuits. Unlike battery-based UPS units, it delivers over 1.2 Ah of effective capacity with a service life exceeding 20 years at 20 °C and requires no maintenance or replacement cells.

Highlights

• Maintenance-free energy storage based on supercapacitors
• 15 A input and output current for demanding DC loads
• DIN rail mounting with screw connections for fast installation
• Integrated electronic fuse protects the module and connected devices
• LED status indication for charge, discharge, and fault conditions

In daily use

The module buffers loads up to 15 A and provides 1.2 hours of backup at a 1 A load. It operates across a temperature range from -25 °C to 70 °C, making it suitable for control cabinets in industrial environments. Parallel operation is supported for applications that require higher capacity.
