Modern factories rely on automated machines that draw heavy starting currents, often causing sudden voltage dips. The QUINT4 power supply addresses this challenge with its dynamic boost, delivering extra current during start-up without interrupting other loads. Its selective fuse breaking ensures that if a fault occurs, only the affected circuit trips while the rest of the production line keeps running. This maintains high uptime and prevents costly disruptions in complex assembly or conveyor systems.
Industrial sites such as oil platforms and mining facilities demand power supplies that survive extreme heat, cold, vibration, and electrical noise. The QUINT4 is designed with a rugged metal housing, wide operating temperature range, and integrated surge protection, ensuring stable 24 V DC power even when exposed to unpredictable conditions. By securing reliable power for controllers, sensors, and safety equipment, it enables continuous operation where reliability is critical.
In large buildings, security cameras, HVAC controls, and automation systems often run on shared power rails. A short circuit in one branch can easily cause total system failure without proper isolation. The QUINT4 uses SFB technology to trip only the faulty line while allowing the rest of the system to function normally. Combined with NFC-based configuration and early warning monitoring, facility managers can fine-tune performance and identify issues before they become major outages.
Continuous processes in chemical plants, water treatment, or power utilities require uninterrupted control signals. Even a brief power interruption can lead to safety risks and high financial loss. The QUINT4 prevents this with a mains-failure bridging time that cushions short dips in input power, keeping PLCs and critical devices online. Its preventive diagnostics alert operators to potential issues in advance, allowing scheduled maintenance and ensuring that vital control systems remain stable.
