Allen-Bradley PowerFlex 70 — Replacement & Cross-Reference

The Allen-Bradley PowerFlex 70 is a discontinued AC drive — Rockwell Automation has retired it from active production. The typical replacement is the PowerFlex 525 for lower-horsepower standard-duty applications, or the PowerFlex 753/755 where the application needs the 70's higher ratings, vector performance, or option cards. If you need a true drop-in to get a line running today, Edmundson Industrial sources new-surplus, used-tested, and reconditioned PowerFlex 70 drives.

Drive substitutions are application-specific. Confirm voltage class, horsepower, duty rating, enclosure, and communication option before ordering. Send the full catalog string from the drive nameplate and we'll verify the match.

Footprint changing on a 753/755 upgrade? Our fabrication side supplies adapter plates, sub-panels, and modified enclosure cutouts so the replacement drive mounts cleanly where the 70 came out — one PO, part and panel together.

Key Specs (platform overview)

Is the PowerFlex 70 still made?

No. Rockwell has discontinued the PowerFlex 70, and new units are no longer in production. Active machines have two practical paths: replace with a current PowerFlex (525 or 753/755 depending on rating and features) at a planned stop, or run surplus drop-ins to defer the engineering work. When the same drive runs multiple machines in a plant, a shelf spare is usually the cheapest downtime insurance available.

FAQ

Is the PowerFlex 70 still being made?
No — Rockwell has discontinued the PowerFlex 70. Replacement units are available through surplus channels like Edmundson Industrial.
What replaces the PowerFlex 70?
PowerFlex 525 for most lower-HP standard-duty applications; PowerFlex 753/755 for higher ratings or applications using the 70's vector control and option cards. Parameters must be rebuilt either way.
Can I buy a new PowerFlex 70?
New-surplus units still exist. We supply new-surplus, used-tested, and reconditioned PowerFlex 70 drives — usually the fastest path when a line is down.
What do you need to quote one?
The full catalog number off the nameplate (the complete 20A… string), acceptable condition, and your need-by date. A nameplate photo works if the string is worn.
Is a used drive safe to install?
Condition is always disclosed before sale — new-surplus, used-tested, or reconditioned — with photos on request, so you know exactly what's arriving before you commit.
