Robitronic Electrical switch with voltage indicator

Electronic receiver switch with voltage indicator for nitro cars

The Powerswitch replaces the mechanical switch for the receiver and servo supply in nitro cars. It switches the receiver supply on and off inside the car and indicates remaining battery capacity and error conditions.

MosFET technology enables the Powerswitch to handle large currents despite its small size; it can be used in large-scale cars with up to 3 servos. Its low current draw when switched off allows it to remain connected to the receiver battery for longer periods. For example, a fully charged 1600 mAh battery would last about 950 days.

Highlights

• Sealed against dust and water
• Programmable for 2S LiPo, 2S LiFe and 5-cell NiMH batteries
• Charge-level indicator with 3 LEDs
• Detection of bad contacts and bad batteries
• Low internal resistance for minimal losses

Notes

• The Powerswitch is only a switch: when switched on, it forwards the input voltage directly to the output. With a 7.4 V LiPo battery, the receiver and servos must be able to handle that voltage.
