Sensor Hub X8

Our UAV's getting bigger and more and more people using several LiPo's in parallel to increase the flight time and/or reduce the current draw from the LiPo packs.

The Sensor Hub X8 was developed to connect up to 8 main batteries in parallel. Which would give an total current range of 8x 200A = 1600A !

If this is still not enough, then install 2x Hub X8 and combine them with an Hub X2, which gives you the possibility to connect up to 16 main batteries in parallel.

REM: You don't have to connect all 8 sensors. Any number from 1 to 8 is possible, as the Hub X8 checks during booting the connected sensors and deactivate any unused sensor input.

Detailed info can be found in the Hub X8 manual page. As well as in the X8 Product guide page.

Power-Cube 1, 2, 3 and 4

The Power-Cube series was developed to match the increasing power demand of bigger UAV’s together with the new Pixhawk 2.1. The installed equipment, such as… Heated IMU’s, Flow sensors, OSD, 2x GPS, Telemetry, Edison board, Gimbal, Camera, Landing gear, Parachute, Digital servos, LED’s, Raspberry Pi 3, Lidar… etc.

With all or some of this equipment the standard power modules are over loaded or at least operating at their upper limit, which means there is a big risk of failure and overheating of the system.

This new series will now take care of all the equipment. Each output is rated for continues current of 10A with max. current at 15A (current limit 20A).

The design is based on the reference design of the LM5116 from Texas Instruments. Without any costs cut, but even improved component selection, such as oversized FET’s, SPEC capacitors from Panasonic… etc.

Sensor Hub X2

This sensor hub is to connect two current sensors in parallel. The current of both sensors will be summarized and passed to the FC. The voltage measurement of the LiPo packs will be collected from both sensors and passed through the Hub to the FC.

The main purpose of this hub is to replace existing protection circuits (like an ideal diode) and to monitor, that both paralleled LiPo’s supply the same current to the system.

Since we monitor the current of both batteries, we will find out very early when a LiPo starts to fail… before it is too late.

If the difference in current is bigger than +/- 10%, the Hub will issue a warning to the pilot via a Power Led and/or buzzer (fast flashing) connected to the Alarm I/O.

If the difference in current is larger than +/- 20%, the Alarm output will be always ON to indicate the fault… the pilot should immediately land and check the batteries.

Additionally, there is a reserve relay contact (alarm) for the user to implement any desired function.

4-14S / 3A Hybrid BEC

It is an switching power supply and in series an linear LDO (LM1764A) to remove the ripple. Due to the component selection, this BEC get's only warm during operation (LDO only 0.35V dropout voltage).

Input and output is protected by Panasonic FM capacitors.
