1.6.3 Power s upply and duty cycle
Power supply:
electric motor ................................................................ 230/220 V AC ±10%, or 24 V AC/DC ±10%
control........................................................................... 230/220 V AC ±10%, or 24 V AC/DC ±10%
transmitter .................................................................................................................see chapter 1.8
Power supply frequency .................................................................................... 50 Hz or 60 Hz ± 2%
Note : At frequency of 60 Hz operating time is reduced by 1.2 times.
Duty cycle (according to EN (IEC) 60034-1.8):
EA SP are designed for remote control:
•
short-time operation S2-10 min
•
intermitted operation S4-25%, 6 up to 90 cycles per hour
EA SPR are designed for automatic regulation:
•
intermitted operation S4-25%, 90 up to 1200 cycles per hour.
Note: EA SP is possible connect with external regulator and use it as regulated EA and for this EA stand
duty cycle and power parameters like for type SPR with built-in regulator.
