Quick Detail

Description

The Bently Nevada 3500/15 Series Power Supplies are half-height modules and must be installed in the specially designed slots on the left side of the rack. The 3500 rack can contain one or two power supplies (any combination of ac and/or dc) and either supply can power a full rack. If installed, the second supply acts as a backup for the primary supply. When two power supplies are installed in a rack, the supply in the lower slot acts as the primary supply and the supply in the upper slot acts as the backup supply. Removing or inserting either power supply module will not disrupt operation of the rack as long as a second power supply is installed. The 3500 Power Supplies accept a wide range of input voltages and converts them to voltages acceptable for use by other 3500 modules. Three Power Supply versions are available with the 3500 Series Machinery Protection System as follows: 1. ac Power Supply 2. High Voltage dc Power Supply 3. Low Voltage dc Power Supply.

125840-01 is a Ac Power Input Module developed by Bently Nevada. The system Power Supplies are half-height modules that must be installed in special slots on the rack's left side. The rack can house one or two power supplies (any combination of ac and/or dc), with either supply capable of powering the entire rack. The second supply, if installed, serves as a backup for the primary supply.

Applications

Provide Continuous AC Power to 3500 Racks

125840-01 delivers 175–250 Vac rms to the rack, enabling operation of all connected monitoring, interface, and control modules in automation and machinery protection systems.

Maintain Rack Operation During Module Maintenance

With two 125840-01 modules installed, the lower module powers the rack while the upper module serves as backup. This setup ensures uninterrupted system operation even when modules are inserted or removed.

Integrate with High Voltage and Low Voltage Configurations

125840-01 can be paired with High Voltage dc Power Supplies or Low Voltage ac Power Supplies, supporting automation systems requiring flexible voltage options.

Protect Modules from Overvoltage Events

The internal fuse in 125840-01 opens above 250 Vac, preventing damage to rack modules while undervoltage events (<175 Vac) do not interrupt operations.

Specifications

Competitive Advantage

Ensure Reliable Power Delivery

125840-01 supplies 175–250 Vac rms to all rack modules, supporting continuous operation of automation and monitoring systems without power interruptions.

Support Redundant Power Configurations

Dual-module installation allows one 125840-01 module to act as primary and the second as backup, maintaining full rack operation during module replacement or fault events.

Operate Across Industrial Temperature and Humidity Ranges

With -30°C to +65°C operating temperature and 95% non-condensing humidity, 125840-01 performs reliably in industrial automation environments.

Flexible Integration with Multiple Power Supplies

125840-01 works with High Voltage dc Power Supplies and Low Voltage ac Power Supplies, enabling system designers to configure racks for varying voltage requirements.

Protect Connected Modules Using Quantified Voltage Limits

The fuse in 125840-01 responds to overvoltage >250 Vac while maintaining operation under undervoltage <175 Vac, ensuring connected 3500 modules are protected while automation systems remain online.
