Product description
The SPS SafetyPowerSwitch is a electronic safety switch for electric drives. 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.
Key features
Switching on and off of electrical motors
The SPS SafetyPowerSwitch serves for switching on and off of electic drives. When using the SPS SafetyPowerSwitch it is ensured that electic drives do not start accidentally and cause insuries e. g. during preparation of the model. The drive is supplied with voltage only when switch is operated consciously.
Anti flash protection
Furthermore the SPS SafetyPowerSwitch prevents the flash occuring when connecting the battery.

Delivery contents
SPS SafetyPowerSwitch, desired switch actuator, screws, operating instruction
Mounting
The SPS SafetyPowerSwitch is looped in between the drive battery and the motor controller. Therefor e. g. 4mm gold plated plugs or sockets must be applied on the input side. The red cable of the SPS is the positive pole, the black one the negative pole. Obeying polarity is mandatory. The output of the SPS SafetyPowerSwitch must be connected to the motor controller according to polarity. The total cable length between motor controller and battery (incl. SPS SafetyPowerSwitch) should be as short as possible. The SPS SafetyPowerSwitch's PCB can be fixed with Velcro tape to an appropriate surface. Alternatively the fixing with a small screw is possible. For using this method there is a small drilling hole at the end of the PCB. Please observe not to shorten the small solderpads beside the hole with the used srew.
Switching on and off
The SPS SafetyPowerSwitch can be switched on and off by using the connected switch actuator. After switching on the SPS SafetyPowerSwitch the status LED of the switch actuator starts shining.
The SPS SafetyPowerSwitch can only be switched on and off by an external switch actuator. Switching on and off of the SPS SafetyPowerSwitch at the housing itself is not possible. One of three available SPS switch actuators is contained within delivery contents.
SPS switch actuators
For the SPS SafetyPowerSwitch three SPS switch actuators are available:
- SPS Gas cap switch actuator
- SPS Pin switch actuator
- SPS Remote switch acutator
All SPS switch actuators must be connected on the SPS switch actuator connector at the "IN" side of the SPS SafetyPowerSwitch.
SPS Gas cap switch actuator
Switching on and off with the SPS Gas cap switch actuator happens with an external magnet which is plugged inside the SPS Gas cap switch actuator's funnel-shaped opening in idle-mode (SPS SafetyPowerSwitch switched off). When magnet pulled out of the opening the SPS SafetyPowerSwitch is switched on. A green LED inside the SPS Gas cap switch actuator's opening indicates the activated system. For deactivating the SPS SafetyPowerSwitch and the complete system the external magnet must be plugged into the opening of the SPS Gas cap switch actuator again.
SPS Pin switch actuator
Switching on and off with the SPS Pin switch actuator happens with an external pin which is plugged inside the SPS Pin switch actuator's opening in idle-mode (SPS SafetyPowerSwitch switched off). When pin is pulled out of the opening the SPS SafetyPowerSwitch is switched on. A green LED inside the SPS Pin switch actuator's opening indicates the activated system. For deactivating the SPS SafetyPowerSwitch and the complete system the external pin must be plugged into the opening of the SPS Pin switch actuator again.
SPS Remote switch actuator
Main article: SPS Remote switch actuator
Switching on and off with the SPS Remote switch actuator happens with an defined receiver channel. Therefor the desired switching points on the transmitter must be programmed. Optionally the SPS Remote switch actuator can be operated additionally with the SPS Pin switch actuator or the SPS Gas cap switch actuator. See details of programming and important hints inside Main article.

Usage of SPS Support capacitor
During switching-on process motor controllers may need more current than during regular operation. In this case a short period high current flow could cause a voltage drop at the motor controller and lead to malfunctions. Such voltage drop can also be caused by high-resistance long cables between the drive battery and the motor controller. This voltage drops at the motor controller can be prevented by soldering a capacitor between SPS SafetyPowerSwitch and motor controller. The SPS Support capacitor provides the current peaks required by the motor controller and unloads the drive battery by decreasing the current flow from the drive battery. So the voltage drop at the motor controller is reduced. The total cable length which is recommended without a capacitor can be seen inside your motor controller's operating manual

Using a power resistor for pre-charging capacitors
Motor controllers have capacitors which provide short current peaks required during the switchin-on process. This capacitors are being charged when the motor controller is switched on, so depending on the capacitor's input capacity a increased current flow may occur. If the total capacity of all capacitors increases 1500µF occuring currents may damage the SPS SafetyPowerSwitch. This can be prevented when capacitors are pre-charged with a lower current before the SPS SafetyPowerSwitch is switched on. Therefor the minus pole can be bypassed with an external power resistor. The power resistor can be soldered directly between minus pole input and minus pole output. If desired it can be switched with a pushbutton.
Power resistor without pushbutton
The power resistor can be soldered directly between minus pole input and minus pole output. The motor controller's capacitors will be charged when the battery is plugged. When capacitors are fully charged the SPS SafetyPowerSwitch's LEDs as well as the LEDs of the connected SPS switch actuator are illuminated. This happens a few seconds after plugging the battery. The SPS SafetyPowerSwitch can now be safely switched on because the motor controller's capacitors are pre-charged, no high current flows can occur.
Power resistor with pushbutton
The power resistor can be soldered directly between minus pole input and minus pole output. A pushbutton can be implemented to make the bridge switchabel. The motor controller's capacitors will be charged when the battery is plugged and the pushbutten is pushed for a few seconds. When capacitors are fully charged the SPS SafetyPowerSwitch's LEDs as well as the LEDs of the connected SPS switch actuator are illuminated. The SPS SafetyPowerSwitch can now be safely switched on because the motor controller's capacitors are pre-charged, no high current flows can occur.
