The Bently Nevada 3500/15 129486-01 is a legacy high-voltage DC power supply module built for the 3500 series monitoring system. This unit converts incoming DC power to run the entire rack assembly reliably. It operates with an input range of 88 to 140 Vdc, making it suitable for various industrial DC bus applications. Manufactured in the U.S.A., this module features built-in protection against voltage faults. Its front-panel Supply OK LED provides immediate visual status confirmation. This 3500/15 module occupies two half-height slots on the left side of the rack. Moreover, it allows a second unit to be installed for full redundancy.
This section details the key electrical parameters of the Bently Nevada 3500/15 129486-01. Its input voltage range spans from 88 to 140 Vdc. The maximum full-rack current draw is 2.5 A. Consequently, it can handle substantial loads without performance degradation.
Regarding protection, the module responds predictably to out-of-range conditions. An under-voltage event does not damage the power supply or the associated PIM. On the other hand, an over-voltage condition triggers the fuse to open on the PIM, safeguarding downstream components. The front panel includes a Supply OK LED, which illuminates when the 3500/15 129486-01 operates correctly. This indicator simplifies troubleshooting and reduces diagnostic time significantly.
Physical installation requires careful attention to the module's dimensions. The 3500/15 measures 120.7 mm x 50.8 mm x 251.5 mm (4.75 in x 2.0 in x 9.9 in). It weighs approximately 1.39 kg (3.06 lb). The two half-height slots are positioned on the rack's left side, and each slot accepts one power supply.
Furthermore, this unit operates across a wide temperature range. Its operating temperature spans from -30 °C to +65 °C (-22 °F to +150 °F). For storage, the acceptable range extends from -40 °C to +85 °C (-40 °F to +185 °F). Additionally, it tolerates humidity levels up to 95%, non-condensing. No minimum rack load is required, offering flexible deployment.
Proper installation ensures optimal performance for the Bently Nevada 3500/15 129486-01. First, power down the rack system entirely before inserting the module. Next, align the unit with the selected half-height slot on the left side. Slide it firmly into place until the connectors seat securely. After that, tighten the retaining screws to fix the module in position. Finally, restore power and verify that the Supply OK LED turns green. For redundant setups, install two units simultaneously in both available slots. This configuration provides seamless failover protection.

Product documentation sheet (quick start guide)
1. Can I install two 3500/15 modules for redundancy?
Yes, the rack provides two half-height slots on the left side. Both can hold a power supply simultaneously, allowing full redundant operation without extra hardware.
2. What happens if the input voltage drops too low?
An under-voltage condition does not harm the power supply or the PIM. The unit simply stops regulating until voltage returns to acceptable levels.
3. Is this module compatible with other 3500 series racks?
Absolutely. The Bently Nevada 3500/15 129486-01 is designed specifically for the 3500 monitoring system and fits all standard racks using this form factor.
4. How do I know the power supply is functioning correctly?
Look at the front panel. The Supply OK LED illuminates when the 3500/15 operates within normal parameters. If the LED is off, check input power and fuse status.
5. What shipping carriers do you use for this item?
