Product basic information

Product Name: 3500/15 AC and DC Power Supplies

Brand: Bently Nevada, under Baker Hughes, used for mechanical equipment condition monitoring systems

Document Information: Technical Data Sheet for Model 141530 Rev. N

Core functions and installation features of the product

（1） Module positioning and redundancy design

Physical specifications: It is a half height module and must be installed in the designated slot on the left side of the rack.

Redundant configuration: The 3500 rack can install one or two power modules (AC and DC can be combined arbitrarily), and a single power module can supply power to the entire rack; If two are installed, the main power supply in the lower slot and the backup power supply in the upper slot can be seamlessly switched in case of a main power failure.

Hot swappable feature: As long as two power modules are installed in the rack, plugging or unplugging either module will not interrupt the rack operation.

（2） Power type and compatibility

Available power types: The 3500 series mechanical protection system supports three power options, as follows:

Universal AC Power

High Voltage DC Power Supply

Low Voltage DC Power Supply

Compatibility limitations:

Universal AC power supply and power input module (PIM) are not compatible with traditional 3500 AC power supply, high-voltage AC PIM, and low-voltage AC PIM.

High voltage DC and low-voltage DC power supplies and their corresponding PIMs are not compatible with traditional 3500 high-voltage/low-voltage DC power supplies and PIMs.

Technical specifications

（1） Input parameters

There are differences in input voltage, frequency, and other parameters among the three types of power supplies, as shown in the table below:

Power type Input voltage range Input frequency Other instructions

Universal AC power supply rated at 110-220 Vac;

Non hazardous area: 85-264 Vac rms;

Dangerous area: 85-250 Vac rms;

Peak value of 120-373 Vac pk 47-63 Hz needs to be used with universal AC PIM

High voltage DC power supply 88-140 Vdc – needs to be used with high voltage DC PIM

Low voltage DC power supply 20-30 Vdc – needs to be used with low voltage DC PIM

Additional notes

Voltage protection: Among all power options, undervoltage will not damage the power supply or PIM; Overvoltage can cause the fuse on PIM to melt.

Full rack current: Universal AC maximum 2.8 A rms; High voltage DC maximum 2.5 A; low voltage DC maximum 11.0 A.

（2） Output and indicator lights

Output function: Convert the input wide range voltage into a voltage that can be used by other 3500 modules.

Front panel indicator light (Supply OK LED): When the power module is working properly, the indicator light is on.

（3） Physical dimensions and weight

Module type, size (width x height x depth), weight

Power module 120.7 mm × 50.8 mm × 251.5 mm (4.75 in × 2.0 in × 9.9 in) 1.39 kg (3.06 lb)

Power Input Module (PIM) 120.7 mm × 25.4 mm × 114.3 mm (4.75 in × 1.0 in × 4.5 in) 0.34 kg (0.75 lb)

（4） Rack space requirements

Power module: It needs to occupy two half height slots on the left side of the rack, each slot can accommodate one power module, and supports the installation of two at the same time to achieve redundant power supply.

Power input module: It is a special half height module that is directly installed behind the corresponding power module.
