Core Features 24V DC Maintenance-Free Lead-Acid Backup Battery: Functions as a robust industrial-grade backup battery designed for 24V DC UPS systems (e.g., Phoenix Contact QUINT-HP-UPS series), providing reliable emergency power during grid outages. It features a 4Ah (ampere-hour) capacity and sealed lead-acid (VRLA, AGM) technology—eliminating the need for electrolyte refills or maintenance, making it ideal for enclosed control cabinets or remote industrial setups where regular upkeep is difficult. High Reliability for Critical Power Backup: Engineered for consistent performance in backup scenarios, with a deep discharge cycle life of ≥300 cycles (at 50% depth of discharge, DoD)—ensuring long-term reliability for critical systems. It delivers stable 24V DC output even during partial discharge, supporting UPS systems to maintain power for 24V DC equipment (e.g., PLCs, sensors) until grid power is restored. Wide Operating Temperature Range: Built to withstand harsh industrial environments, operating reliably in temperatures from -15°C to +50°C—suitable for cold warehouses, warm production floors, or outdoor enclosures (with proper temperature shielding). The AGM (Absorbent Glass Mat) construction prevents electrolyte leakage and thermal runaway, ensuring safe operation across temperature fluctuations. Compact Design & Easy Integration: Features a space-saving, panel-mountable or floor-standing form factor—compatible with standard industrial UPS battery compartments. It includes pre-installed terminal connectors (M8 bolts) for quick, secure wiring to UPS systems, and a built-in status indicator (via optional battery management modules) to monitor charge level—simplifying installation and maintenance for 24V DC backup systems. Safety & Compliance for Industrial Use: Integrates safety features to prevent hazards in industrial settings: Sealed construction: Prevents electrolyte leakage, even if the battery is tilted or mounted vertically. Overcharge protection: Compatible with UPS battery chargers that follow IEC 61056 standards, avoiding damage from overcharging. Short-circuit protection: Resistant to accidental short circuits via robust terminal insulation, reducing fire risk. Typical Applications The Phoenix Contact UPS-BAT-PB-24DC-4AH-1274117 is engineered for 24V DC UPS backup power in industrial systems—ideal for scenarios where short-term uninterrupted power is critical to avoid downtime—with core use cases including: Industrial UPS Backup for PLCs: Serves as a backup battery for 24V DC UPS systems powering PLCs (e.g., Siemens S7-1200, Allen-Bradley Micro800) in manufacturing lines. It provides 5–10 minutes of backup power (depending on load) during outages, ensuring PLC program retention and preventing production interruptions—complying with IEC 61131-2 standards for programmable controllers. Sensor & Control System Backup: Powers 24V DC UPS systems supporting critical sensors (e.g., emergency stop sensors, pressure transducers) and control modules in process industries (e.g., food processing, water treatment). The maintenance-free design avoids downtime from battery upkeep, while wide temperature resistance ensures reliability in harsh environments—complying with IEC 60947-5-2 standards for industrial control devices. Small Industrial Server & Data Logger Backup: Supplies backup power to 24V DC UPS systems for industrial servers, data loggers, or IoT gateways in factory automation networks. It maintains power long enough to save critical data and shut down systems gracefully, preventing data loss—complying with IEEE 802.3 standards for industrial Ethernet. Remote Equipment Backup: Supports 24V DC UPS systems for remote industrial equipment (e.g., off-grid monitoring stations, pipeline sensors) where grid power is unstable. The sealed AGM construction withstands transportation and outdoor conditions, while 4Ah capacity provides sufficient backup for short outages—complying with IEC 62133 standards for rechargeable industrial batteries.
