Power Supply

With high performance and flexibility, this switching power supply is a wise choice for all your electronic power needs.

INTRO :

The Airbot Systems switching power supply is ideal for electronic projects, models, drones, robots and other electronic devices requiring quality power. This power module can be easily integrated into a variety of mounting configurations, providing great flexibility for projects development.

The module incorporates a voltage divider bridge which can be used to measure the input voltage.

INSTALLATION :

The Power supply can be used by two different ways :

STACKED The power supply can be directly integrated into another PCB used as motherboard. It reduces new electronics projects development timeline. Airbot Systems provides all necessary documents to facilitate the integration (3D file of the power supply, Eagle library, Kikad library and PDF). All these files are downloadable for free from our download section

WIRED The power supply can be used as traditional wired BEC by using the accessory PCB provided with each power module. The power supply should be first soldered on the accessory PCB, then you can easyly solder input and output wires from large pads on the accessory board bottom side.

Note : To avoid any damage on the power supplies and grant the reliability, we highly recommand to use anti-spark battery power connector on the power source ( like Amass XT90-S )

TECHNICAL SPECIFICATIONS :

– Supports up to 50.4V input (4S to 12S battery) – Provides up to 3A continuously, and supports momentary spikes up to 4A – User selectable output voltage: 5V, 5.3V or 12V – Optional PCB included for stack or wired use

Dimensions : Power module only : 24*23*6,15mm / 0,94*0,90*0,24in (without cable) Assembled with the optional PCB : 29*23*6,15mm / 1,14*0,90*0,24in (without cable)

5V3 Power Supply : If used to provide over 2A continuously, we highly recommend to use an active cooling in order to limit heat.

LABEL	FUNCTION
V-IN	Power source Input (max 50.4v)
GND	Ground
V-OUT	Power Out. (defined by user on the bottom side / max 3A continuous)
Opt-IN	Optional input which can be used to pass a signal or any other low intensity current (Typically current sensor) Connected to Opt-Out
Opt-Out	Connected to Opt-in
V-Prob	Divider bridge connected to V-IN. Can be used to measure the voltage from the power source. Voltage divider : 16

OUTPUT VOLTAGE SETUP

Output voltage can be defined by the user, and changed anytime to adapt users voltage needs. Solder bridges are present on the bottom face of the module. By default the 3 solder bridges are connected. To define the power supply output voltage, use a sharp tool to cut the layout tracks corresponding to the unwanted voltages (cutter or scalpel). Only the trace of the desired voltage must remain connected. Corresponding voltages are labeled next to each solder bridges TIP : Use a multimeter with continuity test mode to check if the tracks are correctly cut and no longer in contact. Voltage can be changed at anytime by cutting all the layout traces and solder bridge the desired one. Note : If the module is integrated on a mother board, keep an access window to the power module backside to maintain the voltage change possible.
