2. Emergency Power for Safety Systems in harsh industrial environments

For safety-critical systems like emergency lighting, access control, or fire detection in factory settings, consistent power is paramount. The module's 24V DC output and 7 Ah capacity ensure these systems remain operational. Its -15°C to +50°C operating temperature range and IP20 rating make it suitable for typical industrial control cabinets where temperature fluctuations and some dust are present.

Problem Solved

Guarantees continuous power to vital safety and monitoring equipment, even in demanding industrial environments, ensuring personnel safety and operational integrity.

3. Buffering for Actuators and Solenoids in Process Control

In process control, operating critical actuators, valves, and solenoids often requires short, high-current bursts. This battery module, with its 40A rated output and 120A peak current capability for 30ms, can effectively buffer the power supply to these components. This prevents voltage sags on the main 24V DC bus during peak demands, ensuring stable operation of sensitive control electronics.

Problem Solved

Mitigates voltage drops caused by high inrush currents from inductive loads, providing stable 24V DC power for precise control of critical process components.
