Special voltage, frequency needs to be customized in advance.
Special Customizaed Voltage
This guide is provided to assist in the sizing of actuator power supply cables, circuit protection devices and calculation of electrical diversity. The data provided is averaged from actuators of the same size, speed and voltage as recorded from production test data. As such it is not exact electrical data for individual actuators, however is sufficient for the above sizing calculations. Test certificates for individual actuators provide unit specific loadings for the starting/stall and rated torque levels and are available when requested. The data included is for standard duty, 3-phase supplies at the following common voltages only:
Actuators suitable for voltages other than shown above are available on request. In such cases, electrical supply sizing can be determined by using the nearest voltage published in this document.
To quickly access the data for your voltage, click the value in the table above. Important Notes
● Test data not available - insufficient test data available.
● Not available at this voltage - this particular build cannot be produced due to excess current draw. Glossary
●Rated torque - the catalogued torque output of the actuator at full load. Represents a torque switch setting of 100%.
●Starting/Stall - current draw at the nominal rated voltage during the initial start of output movement or under motor stall conditions. SD standard protection prevents stall by limiting torque to approximately 150%of rated torque when torque switch bypass feature is enabled. Stall is also limited to a maximum of 5 seconds.
●Rated Torque Current - the average current draw at the nominal rated voltage when the actuator is producing the rated catalogue torque. ●Average(nominal)Torque - corresponds to approximately one third of the rated catalogued torque. This value has been confirmed after decades of valve automation and provides a representative average for load across typical valve strokes.
●Average (nominal) Current - current draw at nominal rated voltage for average nominal torque (one third rated torque).
Motor Option
Extended duty cycles are available with a higher thermostat and Class H insulation for non-hazardous area applications.
Frequency Converters and UPS
Frequency converters for variable speed drives are not normally recommended as a suitable supply for SD actuators. Where UPS systems are required for back-up operation, the power supply should have negligible harmonic distortion and should output a true sine wave. In general terms actuators are designed to operate on power supplied conforming to recognised international standards such as EN 50160:2010.
Tolerances
The following tolerances may be accommodated for short term operation. It is not intended that long term operation is undertaken at supply voltage levels other than the nominal nameplate values of the supplied actuator. In general, the electrical power supply should conform to BS EN 50160:2007 (Voltage characteristics of electricity supplied by public distribution networks) or equivalent.
The volt drop developed on actuator starting must be minimised by ensuring supply capacity and cable are sufficiently sized. Starting volt drop calculation shall be based on the starting/stall currents published.
Basic parameters
Remark: 1.The electric actuator required by the special technology needs to write clearly and concretely in order. 2.When A+RA300/K30HGP model is A+RS, the working torque is 1000Nm, single-phase power supply, the whole travel time is 30 seconds, and foot-plate installation with integration proportional modulatin with the local operation.
