- 4-mm banana plugs for electrical connections.
- CV and CC modes for constant voltage or constant current operation.
This power supply is particularly suitable for RC chargers requiring an external DC power source, electronic speed controllers, motors, receivers, and compatible test equipment.
Note: The maximum available power depends on the mains voltage, the output settings, and the power consumed by other connected devices.
In addition to its DC output, the PSU650 features three USB-C ports compatible with major fast-charging protocols.
Each port can deliver up to 100W, depending on the needs and compatibility of the connected device.
- 3 USB-C ports: C1, C2, and C3
- Maximum power: 100W per port
- USB Power Delivery 3.0 (PD 3.0)
- Programmable Power Supply (PPS)
- Quick Charge 2.0 and 3.0
- Available profiles: 5V/3A, 9V/3A, 12V/3A, 15V/3A, and 20V/5A
These outputs can be used to power or charge compatible laptops, tablets, smartphones, and cameras.
The SkyRC PSU650 features an intelligent power distribution system between the DC output and the three USB-C ports.
The power allocated to the DC output is prioritized. The remaining power is then automatically distributed among the USB-C devices based on the order in which they were connected.
The first device connected receives the power it needs, within available limits. When a device is disconnected, the freed-up power is automatically redistributed.
This management system allows you to use multiple devices simultaneously without having to manually adjust each USB-C output.
The PSU650 features an LCD screen that makes it easy to monitor operating information.
- Display of total power consumption.
- Displays power consumption for each output: DC, C1, C2, and C3.
- Data updates in real time.
- Full-screen clock function, accessible via the Enter button.
- Power supply remains active while the clock is displayed.
Thanks to its Bluetooth connection, the power supply can also be controlled from a smartphone using the SkyRC app.
The app allows you to:
- Adjust the DC output voltage.
- Adjust the output current.
- Modify power settings.
- Save presets to quickly restore your configurations.
- Perform firmware updates.
GaN (gallium nitride) technology enables compact power electronics while optimizing efficiency and thermal management.
The PSU650 also offers two fan modes:
- Quiet Mode: Reduces fan speed by 50% to minimize noise.
- Performance Mode: Prioritizes cooling for applications requiring more power.
This design allows the power supply to adapt its operation to its environment, whether on a workbench or at a trade show booth.
