The Applications for QUINT-PS/1AC/24DC/3.5

1. Machine Shop Automation – Managing High Inrush Loads

In modern machine shops, motors, servos, and drives often draw sudden spikes of current when they start up. Traditional power supplies may drop voltage or trip, halting production. The QUINT-PS/1AC/24DC/3.5 solves this with its POWER BOOST capability, which delivers up to 1.5 times the rated current for as long as needed. This ensures motors and heavy loads start reliably every time without affecting other circuits. As a result, equipment runs smoothly, downtime is avoided, and operators gain confidence that their machines can handle unexpected load surges without stressing the power network.

2. Distributed Control Systems – Fault Isolation and Reliability

In large-scale automation panels, one faulted branch can bring down the entire control system if not properly isolated. The QUINT-PS/1AC/24DC/3.5 addresses this with Selective Fuse Breaking (SFB) technology, briefly delivering up to six times the rated current to trip only the affected breaker. This prevents a single fault from cascading across the cabinet and shutting down critical processes. By localizing problems quickly, engineers can maintain system availability while troubleshooting. This selective protection makes it an excellent choice for PLC-controlled lines, robotics cells, and other distributed automation networks where uptime is crucial.

3. Harsh Industrial Environments – Proactive Monitoring

Industrial sites with humidity, dust, or corrosive air require power systems that can detect issues before they cause outages. The QUINT-PS/1AC/24DC/3.5 includes preventive function monitoring, continuously checking voltage, current, and operating status. Any irregularities trigger early warnings via LEDs or relay outputs, giving technicians time to respond before failures occur. This predictive approach reduces unplanned downtime and minimizes costly emergency repairs. Whether used in process plants, outdoor panels, or maritime systems, its monitoring capabilities help ensure reliable operation under demanding conditions while giving maintenance teams a clear picture of system health.

4. Power Distribution Panels – Compact Expansion Capability

In electrical panels where space is limited, adding new sensors, relays, or actuators can be challenging. The QUINT-PS/1AC/24DC/3.5 is designed with a slim 32 mm width, making it easy to install on DIN rails even in crowded enclosures. Its ability to run in parallel with other units also allows for redundancy or added capacity without redesigning the panel. Combined with its static boost capability, which supports higher startup currents, it simplifies expansions and upgrades. This makes it an ideal choice for distribution panels in factories, building automation, or retrofitted control cabinets where both space and reliability matter.
