1.6.3Power supplyand dutycycle
Powersupply:
electricmotor................................................................ 230/220VAC ±10%,or 24VAC/DC ±10%
control........................................................................... 230/220VAC ±10%,or 24VAC/DC ±10%

Powersupplyfrequency .................................................................................... 50Hzor60Hz±2%
Note: Atfrequencyof 60Hzoperatingtimeisreduced by1.2times.
Duty cycle(accordingtoEN(IEC)60034-1.8):
EASP aredesignedfor remotecontrol:
• short-timeoperation S2-10min
• intermitted operation S4-25%,6up to90 cyclesperhour
EASPR aredesignedfor automaticregulation:
• intermitted operation S4-25%,90 upto1200cyclesperhour.
