Issue:
Explain the term triple rating, in terms of an industrial control transformers voltage code.
Product Line:
Transformer
Environment:
class 9070 Industrial Control Transformer
Cause:
Triple rating on Industrial Control Transformers
Resolution:
A triple rating on the control transformer`s voltage code basically means that the transformer is designed to successfully operate at voltages slightly different than the nominal voltage at it`s full VA capacity. This is done to allow for different voltage systems that require the same voltage ratios, say 4:1 or 2:1. Units with triple ratings are clearly marked in the Digest 172 with the triple rating expressed on page 12-13.
Example: The 9070T250D1 is a triple rated voltage code unit that can supply 250VA with the following input voltages and the corresponding output:
Input: 240 or 480
Output: 120
Input: 230 or 460
Output: 115
Input: 220 or 440
Output: 110
