In automated production lines, controllers, sensors, and drives require a stable and uninterrupted 48 V supply. The QUINT-PS/1AC/48DC/20 ensures that even when motors or actuators demand extra current during startup, systems continue to run smoothly thanks to its POWER BOOST capability. If a short circuit occurs, SFB technology trips the affected circuit quickly, preventing a single failure from shutting down the entire assembly line. Preventive monitoring further enhances reliability by giving early warnings, allowing maintenance teams to act before issues escalate, keeping costly machinery operating without interruptions.
Remote field stations for oil pipelines, traffic monitoring, or environmental sensors face unstable grid power and temperature extremes. The QUINT-PS/1AC/48DC/20 provides consistent voltage output even during brownouts or fluctuating supply conditions. Its rugged design handles operation from –25 °C to +70 °C and is built for long service life. With built-in status signaling, technicians can identify irregularities without frequent site visits. This reduces operational costs and ensures continuous data reporting from equipment that may be difficult or expensive to access regularly.
Large commercial buildings often rely on interconnected systems such as lighting, HVAC, fire alarms, and security access panels. A dependable power supply is essential to keep them synchronized and functioning. The QUINT-PS/1AC/48DC/20 delivers clean, regulated voltage and provides reserve current for sudden load demands, such as when electronic locks or alarms are triggered. By isolating faulty circuits through selective fuse breaking, the rest of the system remains unaffected. Facility managers also benefit from preventive function monitoring, which helps anticipate potential power disruptions and safeguard overall building safety.
Telecom racks and edge data cabinets require extremely stable power for routers, switches, and radio equipment. The QUINT-PS/1AC/48DC/20 offers low-ripple 48 V output, protecting sensitive electronics from voltage noise. Its dynamic boost capability ensures consistent performance when devices draw sudden surges, such as during system startups or when backup power switches on. With rapid circuit isolation, only the faulty section is taken offline, keeping the rest of the network stable. Integrated diagnostic signaling allows remote supervision, giving operators visibility into power health before downtime affects communication services.
