Safety switch SPS SafetyPowerSwitch 70V 60/120A
Safety Switch SPS SafetyPowerSwitch 70V 60/120A
Product description and features
Electronic safety power switch for electric drives. An anti-lightning function prevents sparks when the battery is plugged in.
The SPS SafetyPowerSwitch separates the motor from the drive battery. The drive remains inactive until it is switched on and therefore non hazardous until activation.
For 2S up to 16S LiPo batteries (6V to 70V). 60A continuous current and 120A peak current – ideal for F3A models.
Connection cable
Battery and controller side: 2 AWG11 silicone connection cables each.
SPS switch actuator for switching on and off
In order to be able to switch the SPS SafetyPowerSwitch on and off, an additionally available SPS switch actuator is required (see “Accessories” tab). This SPS switch actuator is not included in the scope of delivery. The following SPS switch actuators are available:
- SPS gas cap switch actuator (green LED)
- SPS gas cap switch actuator (blue LED)
- SPS pin switch actuator
- SPS remote switch actuator
