Industrial Applications

1. Industrial Control Panel Backup Power

Provides essential short-term backup power for critical 24V DC control systems, PLCs, and HMI panels within industrial control cabinets during brief power outages.

Problem Solved

Prevents data loss, system interruptions, and costly downtime in automated industrial processes by maintaining power to critical components during transient power events. The 24V DC output and 3.4Ah capacity, coupled with a 25A max output, ensure sufficient energy delivery for graceful shutdowns or continued operation for several minutes.

2. Emergency Lighting Support in Manufacturing Facilities

Serves as a reliable backup power source for 24V DC emergency lighting circuits in manufacturing plants or warehouses, ensuring illumination during main power failures.

Problem Solved

Guarantees safe evacuation routes and maintains minimal visibility for operations in the event of a power cut, reducing safety hazards. The 30-minute buffer time at 3.7A is ideal for short-duration emergency lighting, and the -15°C to +50°C ambient temperature range supports typical indoor industrial environments.

3. Remote Telemetry Unit (RTU) Power Stabilization

Offers robust power stabilization and backup for remote telemetry units (RTUs) used in applications like water management or remote infrastructure monitoring.

Problem Solved

Ensures continuous operation of remote monitoring and control equipment despite intermittent power supply from solar panels or unreliable grids, preventing data gaps and maintaining critical communication links. The 24V DC output and life expectancy of 5.65 years contribute to long-term reliability in unattended remote locations, especially when housed in an appropriate IP-rated enclosure (considering the battery module's IP20 rating).
