Model: KS-270C

OEM:

BendixKing

Desc:

Pitch Servo

Part Number :


KS-270C

 

FEATURES

  • Trim Servo used to provide AFCS control of the elevators
  • Contains a servo motor with amplifier and an engage clutch, as well as a torque sensor for trim command generation
  • Outputs a dual-channel trim sense signal with a scale factor of 100mV/in-lb, with a positive differential voltage representing CW torque 
  • Maximum sensed torque is at least 20 in-lb in each direction
  • Also contains a tach feedback signal to provide servo motion sensing
  • Outputs a differential signal with a scale factor of approximately 5.3V for full servo speed
  • Is installed with a KM 275 servo mount, which contains a slip clutch for pilot override
  • The servo receives a differential command input and drives the servo motor with a speed proportional to the magnitued of the command
  • The command polarity will determine direction of the servo rotation
  • The command inputs have an impedance of at least 15K ohms
  • The interface is designed such that an open command signal will not cause a servo drive of more than 25% of full-scale speed
  • Contains a validity circuit which compares the motor voltage against the servo command
  • The actuator outputs a open/ground discrete signal, where ground represents a valid servo
  • If the comparison fails, the servo outputs an invalid signal to the FCC

In relation to NE (New) parts, many OEMs change their prices and availability without any notice to dealers or the industry. Therefore, through the REQUEST or RFQ indication, we ask that customers contact us for the most accurate price and availability.

In relation to SV & OH parts, the used parts aftermarket in the aviation industry is not an infinite supply. It is a dynamic, constantly changing market that is significantly affected by and susceptible to highs and lows in supply and demand. Therefore, although we attempt to, at times, we are unable to predict the exact moment when an item may be available. Once again, through the REQUEST or RFQ indication on our website, we ask that customers contact us for the most current and accurate price and availability.

No, because an autopilot system is installed under an aircraft STC or TC approval, whatever part number servo that is certified in that aircraft must be installed.  In addition, servos usually have different motor speeds for different part numbers. Therefore, not installing the same part number servo in the aircraft could produce an unsafe operating condition.  

Please note that this is not in reference to some servo manufacturers superseding older legacy servos with newer models.  That is addressed in another FAQ.

Negotiating the exchange price of a unit only limits the allowable repair cap for the core unit. Southeast Aerospace's exchange transactions are based on the return of economically repairable core unit. Once the core is received and evaluated, the core repair cost incurred by SEA cannot exceed 75% of the original exchange price. That is, it cannot cost SEA more than 75% of the original OH/SV exchange price collected from the customer. Therefore, when and if an SEA exchange price is discounted, there is a risk that additional charges may be assessed once the core is returned and evaluated.
