1.7.3 Power Supply and Operation Modes
Power supply:
Electric motor............................................................110/120 V AC, 220/230/240 V AC, resp.24 V AC ±10%
Control.................................................................................................................binary inputs 24 V DC ±10%
..input control signal 0/4/12 up to 20 mA, 4 up to 12 mA resp. 20 up to 0/4/12 mA, 12 up to 4 mA,
or 0/2 up to 10 V, or 10 up to 0/2 V
Frequency of power supply .................................................................................................... 50/60* Hz ±2%
* At frequency of 60Hz the operating speed is 1,2 times reduced.
Duty cycle - according to IEC 60034-1, 8:
EA STR 0PA are designed - for remote control:
• short-time operation S2-10 min
• intermitted operation S4-25%, 6 up to 90 cycles per hour
- for automotive regulation:
• intermitted operation S4-25%, 90 up to 1200 cycles per hour.
Note:
The operation modes consist of the loading type, load factor and connection/switching frequency.
