High-Current Power for Demanding Applications

The Bently Nevada 3500/15-05-05-00 delivers 10A continuous current at 24V DC for high-load systems. This higher capacity suits installations with multiple monitoring modules and sensors. The unit provides 240W maximum output at 91% efficiency. Users can power extensive 3500 rack configurations with a single supply.

Enhanced Energy Storage for Extended Ride-Through

Four 1000 µF low-ESR capacitor banks provide 50 ms hold-up time at full load. This expanded capacitance ensures stable output during extended power disturbances. The capacitor banks operate in redundant pairs for enhanced reliability. Low equivalent series resistance maintains ripple below 35 mV peak-to-peak.

Robust Protection for Critical Systems

Overvoltage protection clamps the output at 28.5V DC to safeguard connected modules. Overcurrent limiting restricts output current to 12A during overload conditions. Short-circuit protection activates immediately for output faults. Thermal shutdown triggers at 85°C and automatically restarts after cooling.

Universal Input for Global Deployment

The power supply accepts 85–264V AC or 90–300V DC input without manual switching. This universal input range covers all major power grids worldwide. Users can connect the unit to any standard industrial supply. The module automatically adapts to different voltages for seamless deployment.

Redundant Configuration for High Availability

This power supply supports redundant operation with two modules in parallel. The redundant configuration ensures continued system operation during a single power supply failure. Each unit includes isolation diodes for seamless failover. Users can hot-swap faulty modules without shutting down the monitoring system.

Rugged Mechanical Design for Rack Systems

The module measures 241 x 152 x 25 mm and weighs 1.4 kg for stable rack installation. This half-height form factor fits standard 3500 system racks efficiently. Screw-clamp terminals accommodate wires from 0.5 mm² to 4 mm². The fanless design eliminates moving parts for enhanced reliability.
