SPS SafetyPowerSwitch 70V 140/280A

Electronic safety power switch for electric power systems. An anti-flash-circuitry prevents the sparks during connecting the battery.

The SPS SafetyPowerSwitch separates the motor from the battery. The electric motor drive remains inactive and therefore non hazardous until activation.

High-class silicone connection cable of 4mm² (AWG11) thickness. 6-fold multilayer-board with up to 9mm² copper width.

For 6S up to 16S LiPo batteries (18V to 70V). 140A continuous current and 280A peak current - perfect for F3A models.


Attention: The flash protection function of the SPS does not pre-charge the capacitor within the motor controller! Some manufacturers require the pre-charging of this capacitor. Perhaps the SPS might not work properly in this special case.

Attention: The total capacity of all capacitors inside the ESC including additional capacitors must not exceed the value of 1500µF. In case of doubt ask the ECS's manufacturer.

NOTE: Please see note for charging ESC capacitors in Download section.


NOTE: When using the following Graupner products the galvanic isolation of receiver and drive circuit is not possible. So the SPS Safety Power Switch cannot be used with these modules:

  • Electric Air Module2-14S, Vario HoTT (Item no. 33620)
  • General Engine-Module 2-6S Gr. HoTT (Item no. 33610)
  • General Air-Module 2-6S, Vario Gr. HoTT (Item no. 33611)
  • Voltage Module 2-4S, EH (Item no. 33630)
  • Voltage Module 2-4S, XH (Item no. 33631)
