In packaging or logistics facilities, conveyor motors often draw extra current at startup. The QUINT4-PS/1AC/24DC/3.8/SC provides a short surge capacity through its dynamic boost feature, ensuring smooth acceleration of heavy loads. By supplying the extra current only when needed, it prevents tripping of protective devices and keeps production lines operating without delays. Its monitoring functions also give operators early warning if loads begin to strain the system, reducing the risk of unexpected stoppages.
Control cabinets for building systems such as heating, ventilation, and air conditioning are often space-constrained. This slim 45 mm power supply fits easily into tight panels while maintaining high efficiency to limit excess heat. The ability to deliver a steady 24 V DC output ensures stable operation of sensors and controllers. Predictive monitoring adds another layer of protection, alerting technicians to voltage fluctuations before they disrupt climate control operations in commercial or residential buildings.
Smaller water treatment sites depend on local control units for pumps, sensors, and actuators. These systems require a stable and protected 24 V DC power source to keep operations running even during short supply interruptions. The QUINT4 supply combines mains buffering with robust surge protection, making it ideal for such environments. Preventive diagnostics further ensure operators can detect wear or voltage irregularities early, reducing downtime and safeguarding water quality.
Robotic work cells demand precise, uninterrupted power for drives, controllers, and safety circuits. This power supply delivers consistent 24 V DC while conserving space inside compact control enclosures. During peak load events, such as when multiple actuators activate at once, the dynamic boost capability supplies additional current to prevent undervoltage conditions. At the same time, the device’s continuous monitoring helps maintenance teams anticipate failures, ensuring that robotic systems remain productive with minimal unplanned stops.
