0275 POWER REDUCT.
OFF
Reduction of the maximum output current
Possible settings: OFF, 85%, 75%, 50%
If a motor with lower nominal power is used, the maximum output current should be
adjusted accordingly.
The reduction of the maximum output current also affects the overload-detection!

Auto
Selection of the switching frequency
Possible settings: Auto, 8 kHz, 4 kHz
• Auto (default setting)
In standard operation the HYDROVAR works with a switching frequency of 8kHz in order to
reduce the noise level. At rising temperature inside the HYDROVAR the switching frequency
is decreased to 4kHz automatically.
• 8 kHz - Selection with lowest noise level, but without decrease at rising temperature.
• 4 kHz - Reduce the temperature in the HYDROVAR
