Transformer Options
  • MV 12.5v / 13.5v / 14.5v Multi Voltage output on any single circuit transformer
  • MV1 (1) 12.5v / 13.5v / 14.5v Multi Voltage output on 2, 3 or 4 circuit transformer
  • MV2 (2) 12.5v / 13.5v / 14.5v Multi Voltage outputs on 2, 3 or 4 circuit transformer
  • MV3 (3) 12.5v / 13.5v / 14.5v Multi Voltage outputs on 3 or 4 circuit transformer
  • MV4 (4) 12.5v / 13.5v / 14.5v Multi Voltage outputs on 4 circuit transformer
  • PC Photocell mounted on top
  • RPC Remote photocell with 19a² cord
  • R 24V AC Relay control. (For use with existing irrigation controllers)
  • 220V 220v Input / 12.5v output in 300w increments (no multi voltage)
  • 240V 240v Input / 12.5v output in 300w increments (no multi voltage)
  • 277V 270v Input / 12.5v output in 300w increments (no multi voltage)

Important Notice: Low voltage electronic transformers must be tested under load with a analog meter to achieve accurate results. Testing the transformer with a digital meter will produce an invalid reading of aœno outputa. This characteristic is unique to electronic transformers that produce a square sine wave. We recommend use of an analog meter for testing with the transformer loaded to at least 20% of its rated output. Most electronic transformers returned as defective are actually good due to testing methods in the field that did not follow the above requirements.
