The Applications

1. Industrial Machine Control Panel – Ensuring System Redundancy

In oil refineries and other heavy industries, every second of uptime counts. Control panels managing pumps, valves, and sensors must remain powered even when one supply fails. By using the QUINT4-PS/1AC/24DC/5 in a redundant setup, a secondary unit instantly takes over if the primary drops out. This seamless handover prevents costly downtime and keeps processes stable. Its selective fuse-breaking feature isolates only the faulty circuit while other loads keep running, which is critical for complex, safety-sensitive operations.

2. Automation and LED Lighting Systems – Reliable Low-Voltage Power

Smart buildings and industrial facilities increasingly depend on automated lighting and sensor systems. These installations require stable 24 V DC power to prevent flickering, misreadings, or communication errors. The QUINT4-PS/1AC/24DC/5 provides a clean, regulated supply that supports distributed loads such as LED fixtures, HVAC controllers, and smart monitoring devices. Its efficiency reduces wasted energy, while preventive monitoring ensures potential issues are flagged before failure. The result is a power source that enhances comfort, energy savings, and safety in both residential automation and large-scale facility management.

3. Machine Tools and Safety-Compliant Control Circuits

Manufacturing environments demand compliance with strict safety standards, especially for low-voltage circuits in machinery. The QUINT4-PS/1AC/24DC/5 delivers safe and isolated 24 V DC power that meets global norms for operator protection. This makes it ideal for control panels on CNC machines, robotic arms, and automated conveyors. By minimizing electrical interference and offering reliable overload protection, it ensures sensitive control circuits remain stable. Its robust housing and wide operating temperature range also allow it to perform consistently in tough factory conditions where vibration, dust, and heat are common.

4. Training Benches and Development Systems – Flexible Expansion

In education labs, R&D setups, or hobby automation projects, versatility and safety are top priorities. The QUINT4-PS/1AC/24DC/5 provides ample power capacity for programmable logic controllers, actuators, and multiple sensor modules, making it suitable for experimentation and expansion. Students and engineers can add more devices without replacing the supply, thanks to its static boost function. Dynamic boost helps power up components with higher inrush current, ensuring smooth operation even with demanding test loads. This combination of flexibility and reliability makes it an excellent choice for training benches and prototype development environments.
