Compatible Replacement & Equivalent Models
When the original 3500/15 127610-01 is unavailable or end-of-life, the following models are commonly evaluated as replacements. Always verify electrical and mechanical compatibility before substitution:
- Bently Nevada 3500/15E (176449-01) — Enhanced version with extended diagnostics; direct form-fit-function replacement in most rack configurations.
- Bently Nevada 3500/15 (127610-02) — Revised revision; functionally equivalent, confirm firmware compatibility with your rack.
- Bently Nevada 3500/15 DC (127610-03) — DC input variant; suitable only if site power is DC; not a direct AC replacement.
- Third-party 3500-compatible power supplies — Available from authorized aftermarket suppliers; must meet OEM voltage/current specs and rack connector pinout. Contact Konmask for vetted options.
Note: Konmask supplies both genuine OEM and verified equivalent modules. Contact us to confirm the best fit for your system revision.

Selection Guide
Use the following criteria to select the correct power supply for your 3500 rack:
- Input power type: If site power is AC (85–264 VAC), select 3500/15 (127610-01) or 3500/15E. If DC, select 3500/15 DC variant.
- Redundancy requirement: For SIL-rated or critical applications, install two power supply modules for hot-standby redundancy.
- Rack population: A fully populated 3500 rack (16 monitor modules) requires adequate power budget — verify with Bently Nevada rack power calculator or contact Konmask engineering support.
- Revision matching: Match the power supply revision to your rack firmware version to avoid compatibility warnings. Konmask can assist with revision verification.
- Replacement vs. upgrade: If upgrading to 3500/15E, confirm your rack supports the enhanced diagnostics feature set.

Replacement & Compatibility FAQ
Q: Can I use the 3500/15E (176449-01) as a direct replacement for the 3500/15 (127610-01)?
A: In most cases, yes. The 3500/15E is backward-compatible with standard 3500 racks. Verify your rack firmware version supports the enhanced module before installation.
Q: Can I run a 3500 rack with only one power supply?
A: Yes, a single 3500/15 is sufficient for normal operation. A second unit is recommended for redundancy in critical or SIL-rated applications.
Q: What happens if the power supply fails?
A: The rack will de-energize all monitor modules. In a dual-supply configuration, the second supply takes over automatically with no interruption to monitoring.
Q: Is the 3500/15 127610-01 still in production?
A: Bently Nevada has transitioned to the 3500/15E for new orders. The 127610-01 is available as a spare/replacement through authorized aftermarket channels such as Konmask.
Q: Do you provide a warranty?
A: Yes. Konmask provides a standard warranty on all supplied units. Contact us for warranty terms specific to your order.
Q: Can you verify authenticity before I purchase?
A: Yes. We provide pre-shipment photos, label verification, and CoC documentation upon request.
