Notes: Internal algorithms automatically reduce maximum current limit when heatsink temperature is >85°C or battery voltage is
outside the allowed limits. Heatsink temperature is measured internally near the power MOSFETs.
2-minute ratings are based on an initial controller heatsink temperature of 25°C and a maximum heatsink temperature
of 85°C. No addtitional external heatsink is used for the 2-minute rating test.
1-hour ratings assume that only one motor (traction or pump) is running for the test. For a combined rating, contact
your Curtis customer support engineer for power dissipation charts.
