The Bently Nevada 3500/15 129478-01 is a High Voltage DC Power Input Module, commonly referred to as a PIM. This component works alongside the high-voltage DC power supply to bring external DC power into the 3500 monitoring system rack. It accepts an input voltage range of 88 to 140 Vdc and supports a maximum full-rack current draw of 2.5 A. Manufactured in the U.S.A., this module features a front-panel Supply OK LED that confirms proper operation. Additionally, it provides essential protection against voltage faults, ensuring the safety of downstream rack components. This 3500/15 PIM occupies a single half-height slot, making it a space-efficient solution for system integration.
This section covers the core electrical characteristics of the Bently Nevada 3500/15 129478-01. Its nominal input voltage range is 88 to 140 Vdc, which aligns with standard industrial DC bus systems. The module handles a maximum full-rack current draw of 2.5 A under full load conditions.
Furthermore, the 3500/15 129478-01 includes robust out-of-range protection. An under-voltage condition will not damage the PIM or the connected power supply. However, if an over-voltage occurs, a fuse on the PIM opens immediately to protect sensitive rack electronics. The front panel also features a Supply OK LED. This indicator lights up when the input power is within acceptable limits and the module operates normally, which greatly simplifies field diagnostics.
The physical design of the Bently Nevada 3500/15 129478-01 is optimized for easy rack integration. Its dimensions measure 120.7 mm x 25.4 mm x 114.3 mm (4.75 in x 1.0 in x 4.5 in). The module weighs only 0.34 kg (0.75 lb), which minimizes mechanical stress on the rack backplane. It occupies a single half-height slot on the left side of the 3500 rack enclosure.
Regarding environmental tolerance, this PIM performs reliably under extreme conditions. Its operating temperature ranges from -30 °C to +65 °C (-22 °F to +150 °F). For storage, it can withstand temperatures from -40 °C to +85 °C (-40 °F to +185 °F). Moreover, it supports humidity levels up to 95%, non-condensing. No minimum rack load is required, so you can install it without additional dummy modules.
The Bently Nevada 3500/15 129478-01 carries a comprehensive set of international approvals, making it suitable for global deployment.
FCC: Complies with Part 15 of the FCC Rules. It does not cause harmful interference and accepts any interference received.
EMC: Meets European Community Directive 2014/30/EU. It follows standards EN 61000-6-2 (Immunity) and EN 61000-6-4 (Emissions) for industrial environments.
Electrical Safety: Conforms to LV Directive 2014/35/EU and standard EN 61010-1.
RoHS: Complies with Directive 2011/65/EU, restricting hazardous substances.
Maritime: Approved by DNV GL for ships and offshore units. Also meets ABS Steel Vessels Rules and Offshore Units standards.
Installing the Bently Nevada 3500/15 129478-01 is straightforward. First, ensure the rack is powered off completely. Next, select an empty half-height slot on the left side of the rack. Then, align the PIM with the slot guides and slide it in gently until the rear connector mates securely. After that, fasten the retaining screw to lock the module in place. Finally, apply power and check that the Supply OK LED turns on. For redundant power input configurations, you can pair this PIM with a second unit in the adjacent slot, though each PIM typically serves one power supply.

Product information insert
1. What is the primary function of the 3500/15 129478-01?
This PIM receives external high-voltage DC power (88-140 Vdc) and feeds it into the 3500 rack. It works with the corresponding power supply module to energize the entire monitoring system.
2. What happens if the input voltage exceeds the safe limit?
The module includes a protective fuse that opens during over-voltage events. This action isolates the rack from harmful voltage spikes and prevents damage to other components.
3. Is this PIM compatible with redundant power supply setups?
Yes, the Bently Nevada 3500/15 129478-01 can be used in redundant configurations. Each power supply requires its own PIM, and the rack accommodates two units side by side.
4. What certifications does this module hold?
It complies with FCC Part 15, EMC Directive 2014/30/EU, LV Directive 2014/35/EU, RoHS 2011/65/EU, plus DNV GL and ABS marine approvals. This makes it suitable for industrial, offshore, and maritime applications.
5. How do I verify correct installation?
After power-up, observe the front-panel Supply OK LED. A steady green light indicates normal operation. If the LED remains off, check the input voltage and fuse condition immediately.
6. What shipping carriers do you use?
All orders are shipped via Fedex, UPS, or DHL with tracking numbers provided for every shipment.
