Product Details

125840‑01 is high‑voltage AC PIM power input module for Bently Nevada 3500/15 power system. It is not a standalone power supply,must be used together with 127610‑01 power supply module to form a complete high‑voltage AC power unit.

It receives 175‑264VAC field mains power,provides fuse protection and input filtering,then transfers power to 127610‑01 for DC conversion and backplane power distribution. The rack can install dual‑PIM+power‑supply for redundant power configuration,realize non‑stop hot‑swap replacement.

It occupies half‑height dedicated power slot on the left side of 3500/05 rack. 125840‑02 is low‑voltage AC PIM version for 85‑132VAC input scenario.

Note: This is legacy 3500 series spare component,widely used for replacement of turbine and compressor TSI monitoring & protection systems.
