Description
Overview
The 3500/15-07-07-05 is a low-voltage DC power supply module engineered for Bently Nevada 3500 Series machinery protection systems. Combined with the associated 133292-01 and 133300-01 Power Input Modules (PIMs), the unit converts incoming 24 Vdc-class power into regulated internal DC outputs used by all rack-mounted monitoring modules.
The power supply installs into the dedicated left-side supply compartment of the 3500 rack. Systems can be configured with either a single supply or a fully redundant dual-supply arrangement. When two modules are installed, automatic transfer to the backup supply maintains uninterrupted rack operation in the event of a primary supply fault.
The matching PIMs are mounted on the rack backplane and provide conditioned DC input handling, fuse protection, surge suppression, and electrical isolation for high-availability industrial environments.

FAQ
What input voltage is required for the 3500/15-07-07-05?
The module operates from a 20–30 Vdc input range with a nominal supply voltage of 24 Vdc.
What is the function of the 133292-01 and 133300-01 PIMs?
These PIMs provide DC input termination, isolation, surge suppression, fuse protection, and power conditioning for the rack power system.
Can the module operate in redundant mode?
Yes. Two power supplies can be installed for automatic backup operation and increased system availability.
Is the module hot-swappable?
The module may be replaced during operation when a second redundant supply is installed and active.
