Replacement of obsolete Satchwell TR Series 230 V ac / 24 V ac Transformer by S-E TR Series 230 V ac / 24 V ac Transformer

Issue

Satchwell TR Series 230 V ac / 24 V ac Transformer requires replacement.

Environment

Satchwell TR1 (25VA), TR2 (50VA), TR3 (80VA), TR4 (200VA) and TR5 (300VA) 230 V ac / 24 V ac Transformers.

Cause

Obsolescence of Satchwell TR1, TR2, TR3, TR4 and TR5 230 V ac / 24 V ac Transformers.

Resolution

  1. Replace Satchwell 871-1-201 TR1 (25VA) 230 V ac / 24 V ac Transformer with S-E TR 32 (32VA) 230 V ac / 24 V ac Transformer SE part number 3413032000.
  2. Replace Satchwell 871-1-202 TR2 (50VA) 230 V ac / 24 V ac Transformer with S-E TR 60 (60VA) 230 V ac / 24 V ac Transformer SE part number 3413060000.
  3. Replace Satchwell 871-1-203 TR3 (80VA) 230 V ac / 24 V ac Transformer with Transformer of another manufacturer's origin.
  4. Replace Satchwell 871-1-204 TR4 (200VA) 230 V ac / 24 V ac Transformer with Transformer of another manufacturer's origin.
  5. Replace Satchwell 871-1-205 TR5 (300VA) 230 V ac / 24 V ac Transformer with Transformer of another manufacturer's origin.

The S-E TR range of Transformers provide the same functionality as the Satchwell TR range of Transformers but differ in appearance, dimensions and the range of VA ratings available.

Specification EN 60742, with which the Satchwell range of Transformers complied, has been superseded by Specification EN 61558, with which the S-E range of Transformers comply.
