Micro Joule S5A2 ESC for 2-3 Cell Li-Po

The Cirrus Micro-Joule S5A2 Electronic Speed Control is designed for micro electric aircraft. Its factory installed JST plugs make it easy to install in most micro electrics. For those with experience, weight can be saved by direct wiring to the motor. The Micro-Joule S5A2 is designed to extend motor and battery life and flight time. Its high frequency and smooth powerband are programmed to eliminate current loss and to reduce motor brush arcing.

More Information

The S5A2 Micro Joule Specifications:

  • Dimensions: 8 x 9 x 5 mm
    • 925102
  • Input Voltage: 4 - 8 volts
  • Continuous Current: 5 amps
  • Surge Current: 7 amps
  • Switching Frequency: 2000 Hz
  • Weight (wires and plugs): 2 grams
  • Receiver Power: BEC
  • Auto Cutoff (safe voltage protection): 3v
  • Resistance: 0.03 ohms
  • BEC Output: 0.5 amps
  • Anti-Noise Technology

Features:

  • Electronic Arming. Throttle must be in "low" position before ESC can arm.
  • High Frequency. This ESC operates at 2000Hz. This provides smooth motor response at low throttle setting and allows the motor to run cooler.
  • Cancel the delay for reset at normal operation: After the safety has been set the first time, when the throttle is set again to minimum (the reset point), the ESC does not need any delay time for reset. The pilot can apply the throttle any time, the output will begin immediately.
  • BEC / Auto-Cutoff Reset: After the auto-cutoff has engaged, (when the battery has reached the minimum safe voltage) the ESC will reset after the throttle stick is held in the "off" position. Low battery voltage will result in the motor cutoff but reserve battery power can be used to reset the speed control in the air for the safe return to the field.
