Valcom VPB-260 Phone System Battery – Fully Filtered Back-Up Power for Reliable Communications

The Valcom VPB-260 Phone System Battery is a purpose-built, fully filtered back-up power supply engineered to keep essential communications alive when the primary power source fails. In environments where uptime matters—corporate offices, healthcare facilities, hospitality venues, and critical security or paging systems—the VPB-260 acts as a dependable buffer that preserves call quality, continuity of service, and the integrity of your telephony network. This unit is designed with safety and reliability in mind: input and outputs are fuse protected to guard against short circuits and power anomalies, while the charger circuit provides a constant voltage charged current limited to 1.5 amps across two Gel Cells, ensuring safe, steady charging without overstressing the batteries. A floating charger reference minimizes ground loop issues, which can otherwise introduce noise or instability into sensitive phone lines. A built-in power-on LED delivers immediate, visible confirmation that the backup battery is online and ready to respond during outages. The VPB-260’s compact enclosure and straightforward wiring make it easy to integrate into existing Valcom or multi-vender telephony installations, offering a clean, reliable solution to protect critical communications infrastructure. Whether you’re safeguarding a small office’s voice system or ensuring uninterrupted paging in a larger facility, this battery backup unit is designed to deliver dependable performance with minimal maintenance. By providing clean, stabilized power to the two Gel Cells while isolating the charging circuit from ground references, the VPB-260 minimizes interference and helps extend the life of your battery bank and connected equipment. In short, the VPB-260 is a practical, cost-effective way to improve resilience, reduce downtime, and maintain professional communication standards under power outage conditions.
