GKSA-Series Integrated Electric Actuator

GKSA series electric actuator is intelligent intergral actuator, it uses eletronic component instead of mechanical components with modular structure. Frequency conversion intelligent actuator built-in frequency converter, so as to achieve reasonable use of energy.

Standard Design of GKSA-Series Integrated Electric Actuator

  • Standard actuators: short-time duty S2-15 min acc. to DIN EN 60034

  • Modulating actuators: intermittent duty S4 / S5 acc. to DIN EN 60034: min. 25% duty cycle, 1200 c/h for all tripping torque and output speed combinations in the Temperature range from -20°C to +60°C

  • Protection class IP67 acc. to DIN EN 60529 (IP68 on request)

  • Motor insulation class F

  • Electronic motor protection, automatic phase sequence correction

  • Start-up current lower than rated current

  • Line voltage tolerance -10% / +15% in the chosen voltage range, frequency range from 40 to 70 Hz

  • Permissible ambient temperature: -20°C to +60°C (-4°F to +140°F), higher temperatures on request

  • Double sealed electric connection:(dust and water-protected when plug withdrawn)

  • Separate mounting of the electronics unit possible hand crank/wheel for emergency operation (disconnected during motor operation!)

  • "Non intrusive" after adjustment of the end positions of the valve (PROFITRON)

  • Different output speeds, adjustable for OPEN, CLOSE, Emergency OPEN and Emergency CLOSE (PROFITRON)

  • Travel dependant cut-off continuously adjustable 3 reference torque curves of the valve can be stored (PROFITRON)

  • Operator guidance via display in 9 languages (PROFITRON) external 24 V DC supply for electronics unit possible as standard

  • Running indication

Features of GKSA-Series Integrated Electric Actuator

Simplify structure,reasonable---use electronic components instead of mechanical components,adopt modular structure.

Protection grade:lowest level is IP67, meet the DIN EN 60529 standard.(Note: can provide IP68 protection grade when needed).

Seperate installation:when installation space is not enough, the temperature is too high, the vibration is excessive or the debug and test on-site is hard, then intelligent control unit and main part can be installed separately.
