Description Product Introduction A 3500 rack full of vibration monitors is useless if the power quits. The 3500/15 sits in the leftmost slots—slots 1 and 2 if you’re running redundant—and does exactly one job: convert incoming 24 VDC to clean, regulated power for the backplane. It’s not fancy, but when it fails, the whole rack goes dark. Unlike the older 3500/05 power supply, the /15 accepts a wider input range (18-30 VDC) and runs cooler. Honestly, that wider range has saved my butt on sites with suspect DC bus voltage. We’ve seen them ride through dips that would have reset the older units. The 127610-01 is the actual PSU card you slide in; the part number on the front panel might just say 3500/15, but the module itself carries the 127610-01 designation. Key Technical Specifications Parameter Value Model Number 3500/15 (Rack Assembly) Module Part Number 127610-01 Brand Bently Nevada Series 3500 Input Voltage 24 VDC nominal (18–30 VDC operating range) Output Power 85 Watts (maximum) Rack Slots Occupied 1 slot per power supply Redundancy Support Yes—supports dual redundant configuration (two PSUs in same rack) Protection Reverse polarity protection, overcurrent limiting Indicators Front-panel OK LED (green) Compatible Racks 3500/05, 3500/10, 3500/20 Weight Approx. 0.45 kg (1 lb) Firmware / Software Versions & Upgrade Notes Here’s the thing about the 3500/15—it’s a power supply. It has no firmware. No software. No configuration. You slide it in, connect the 24 VDC, and it either lights up the green OK LED or it doesn’t. What does have firmware is the 3500 Rack Interface Module (RIM) that sits in slot 1. That module communicates with the power supplies to report their status to the system. If you’re seeing a power supply alarm in the software, check: The actual 24 VDC input at the terminals The seating of the 127610-01 in the rack (reseat it) The RIM configuration—it might be set to expect a redundant pair when only one is installed No upgrades here. No rollback. If it’s dead, you replace it. Compatibility & Replacement Matrix Use this when swapping power supplies or building a 3500 rack. Original Model Replacement Model Compatibility Level Key Notes 3500/15 127610-01 3500/15 127610-01 Drop-in Identical part. Direct replacement. 3500/15 125712-01 3500/15 127610-01 Drop-in 125712-01 is an older version (125 VDC input). The 127610-01 is for 24 VDC—check your rack input voltage. Not cross-compatible if voltage differs. 3500/15 127610-01 3500/05-01-01-00-00 Needs Adaptation The /05 is a complete rack with built-in power. You can’t swap just the PSU; you’d replace the entire rack assembly. 3500/15 127610-01 3500/20 125744-02 Incompatible That’s a high-voltage bulk power supply for the 3500/20 rack. Different physical size and input range. 3500/15 127610-01 3500/15 127610-02 Drop-in The -02 suffix indicates a different input voltage (probably 48 VDC or 110 VDC—verify your system voltage). If your voltage matches, it’s a drop-in.
