AUMA SGExC 05.1 - Features and Functions of Actuator Controls

12.2 Features and functions of actuator controls
For mains voltage and mains frequency, refer to name plates at the controls and the motor
Permissible variation of the mains voltage: ±10 %
Permissible variation of the mains frequency: ±5 %
Option: Permissible variation of the mains voltage: ±30 %
Power supply
Mains frequency
24 V DC +20 % / –15 %
Current consumption: Basic version approx. 250 mA, with options up to 500 mA
The external power supply must have a reinforced insulation against the mains voltage in
accordance with IEC 61010-1 and may only be supplied by a circuit limited to 150 VA in ac-
cordance with IEC 61010-1.
External supply of the electro-
nics (option)
Current consumption of the controls depending on the mains voltage:
For permissible variation of mains voltage by ±10 %:
●
100 to 120 V AC = max. 740 mA
●
208 to 240 V AC = max. 400 mA
●
380 to 500 V AC = max. 250 mA
●
515 to 690 V AC = max. 200 mA
For permissible variation of mains voltage by ±30 %:
