Vintage Rovex Industries Ltd “The National Power Unit” (MP.1770) transformer-rectifier.
Made in Westwood, Margate, Kent, England.

Input: 200–250V AC, 50–60Hz

Output: 12V DC, 1 AMP (12VA)

Feature: Protected by self-resetting thermal cut-out

Includes original printed instruction sheet.

This unit was designed for use with Tri-ang Hornby model railways during the 1960s/70s, providing reliable DC power from standard AC mains.

New in box but untested.

These MP.1770 units are much harder to find than the standard Tri-ang power controllers of the period, as they were produced in smaller numbers under the “National” branding. This makes them an appealing piece for collectors of Rovex, Tri-ang and Hornby model railway equipment.

Please study pictures as they form part of the description.
