High Capacity Security System Batteries 12V 38Ah For Public Broadcast

The GP38-12 is a professional-grade, high-capacity Valve Regulated Lead-Acid (VRLA) battery utilizing reinforced AGM (Absorbent Glass Mat) technology. With a massive 38Ah energy reserve, it is specifically designed for large-scale constant voltage amplifier arrays, remote wireless broadcasting base stations, and fire command centers. It serves as the core energy hub to ensure "uninterrupted sound coverage" in public areas during extreme power outages.

Key Specifications

• Model: GP38-12
• Nominal Voltage: 12V
• Nominal Capacity: 38Ah (20HR)
• Design Life: 10 years

Why GP38-12 is the Ultimate Choice for Large Broadcasting Projects?

• Massive Reserves for Long-Term Outages:
  Compared to standard 7Ah or 17Ah batteries, the GP38-12 provides several times the runtime. In the event of a power failure in a large building, it can sustain broadcasting systems with thousands of watts for hours, ensuring evacuation and reassurance messages play continuously.
• Ultra-Stable Output to Prevent Distortion:
  Large-scale sound reinforcement systems generate massive current pulses during peak output (such as high-decibel sirens). The 38Ah capacity implies ultra-low internal resistance and a high discharge platform, effectively preventing "clipping" or "audio lag" caused by voltage fluctuations.
• Supports Large-Scale Amplifier Clusters:
  In a central equipment room, a battery bank composed of GP38-12 units can provide centralized backup for multiple high-power amplifiers (500W/1000W+), simplifying the overall power management architecture.
• Enhanced Durability and Longevity:
  Featuring thickened plates and a specialized lead-calcium alloy, this battery offers significantly enhanced cycle performance. It maintains excellent chemical stability even in poorly ventilated telecommunication rooms or outdoor control cabinets.

Typical Application Scenarios

• Major Transportation Hubs: Emergency evacuation systems for airport terminals and large high-speed railway stations.
• City-Wide Emergency Broadcasting: High-power remote broadcasting terminals deployed on outdoor poles or towers.
• Stadiums & Convention Centers: Supports complex zoned sound networks consisting of hundreds of speakers.
• Industrial Park Fire Linkage: Acts as the primary backup power for factory-level fire alarms and voice guidance systems.
