Comparison of DOL and Sure-Start 6

These oscillograms show the starting current waveforms.

No load voltage: 254 volts rms

These waveforms show the effect of the motor start current on the voltage at the condenser unit terminals.

The same waveforms but stretched and showing the voltage.

 

Start current of 143 Amps rms

254 volts falling to 213 volts rms

 

Start current of 42.7 Amps rms

254 volts falling to 245 volts rms
