Allen-Bradley PowerFlex 700 / 700S — Replacement & Cross-Reference

The Allen-Bradley PowerFlex 700 (20B) and high-performance PowerFlex 700S (20D) are discontinued AC drives. The modern path is PowerFlex 753 for general use and PowerFlex 755 where the 700S's high-performance or position control is required. For a fast restart, Edmundson Industrial sources new-surplus, used-tested, and reconditioned PowerFlex 700 / 700S drives and control/power boards.

Upgrading a 700 or 700S to a 753 / 755? The 750-series footprint differs from the 700. Our fabrication side supplies adapter plates, sub-panels, and modified enclosure cutouts so the new drive mounts where the old one came out — one PO, part and panel together.

Key Specs

Is the PowerFlex 700 / 700S still made?

No. Rockwell has discontinued the PowerFlex 700 and 700S; the 750-series (753/755) are the successors. The 700 and 700S run countless plants, so surplus drives and boards are the fast fix when a line is down. Retrofit to a 753/755 at a planned stop; because the footprint changes, our fabrication side adapts the panel so the new drive mounts cleanly.

FAQ

Is the PowerFlex 700 / 700S discontinued?
Yes — both are discontinued. Replacement units are available through surplus channels like Edmundson Industrial.
What replaces a PowerFlex 700 or 700S?
PowerFlex 753 for general-purpose 700 applications; PowerFlex 755 for 700S high-performance or position control. Parameters are rebuilt and the footprint changes.
Can you supply just the control or power board?
Yes — we source 700 / 700S control and power boards. A board-level fix often restarts a drive faster and cheaper than a full replacement.
Can I buy a new PowerFlex 700?
New-surplus units still exist. We supply new-surplus, used-tested, and reconditioned 700 / 700S drives, usually the fastest path when a line is down.
What do you need to quote one?
The full catalog string (the complete 20B / 20D… number) or a nameplate photo, acceptable condition, and your need-by date.
