The 3500/15-07-07-05 is a Low Voltage DC Power Supply for the Bently Nevada 3500 Machinery Protection System. It consists of the 133292-01 main processor and 133300-01 Input Module, converting 24V DC field power into regulated voltages for the rack backplane to power monitors and transducers.
Designed for full power redundancy, two modules allow hot-swap replacement without interrupting system operation. This configuration is optimized for low-voltage industrial DC grids, with noise filtering and surge suppression.

Ideal for oil & gas facilities or remote substations powered by 24V DC battery banks. Using the 133300-01 PIM, it protects sensitive monitoring logic from electrical transients on the DC bus.
Does the 3500/15-07-07-05 support 110V DC?
No. This low-voltage version is rated for 20–30 VDC. For 110V DC, a high-voltage 3500/15 is required.
Can the 133292-01 module be replaced while running?
Yes. With redundant power supplies, the secondary module maintains rack power during a hot-swap.
