Adapts M‑2001 Series Digital Tapchanger Control to replace Reinhausen

MK20 Control

• Connects easily to the M‑2001 Series Digital Tapchanger Control, using

four mounting screws and a 24‑pin connector

• Provides direct mechanical and electrical replacement of the Reinhausen

MK20 Control

• Provides built‑in shorting protection when the M‑2001 Series Digital

Tapchanger Control is removed

The M‑2220 Adapter Panel combines with the M‑2001 Series Digital

Tapchanger Control to provide convenient, direct mechanical replacement

for Reinhausen MK20 control.

M‑2220 Differences Relative to the MK20: Revised connections will be

needed if paralleling transformers using the circulating current method with

the Reinhausen SKB5 or SKB20 Parallel Control Units (please contact

Beckwith Electric Company for further information).

The M‑2220 provides one normally open contact for the Raise and Lower

outputs. The MK20 normally closed contacts for Raise and Lower are not

provided on the M‑2220.
