MATEK Mateksys SERVO PDB W/BEC User Manual

1. Nhanganyaya

The MATEK Mateksys SERVO PDB (Power Distribution Board) with BEC (Battery Eliminator Circuit) is designed to provide a stable and adjustable power supply for servos in RC (Radio Control) applications. It is particularly useful for flight controllers that lack a dedicated BEC for servos, or for large-scale RC airplanes where reducing circuit loss and voltage drop on servo power wires is critical. This manual provides detailed instructions for the proper installation, operation, and maintenance of your SVPDB-8S.

4. Setup uye Kuiswa

Careful installation is crucial for the proper functioning and longevity of your SERVO PDB. Please follow these steps:

4.2 Input Power Connection

Connect your main battery voltage (5.5V to 36V) to the Vbat IN uye G (Ground) pads on the PDB. Ensure correct polarity.
YAMBIRO: This board has no protection for reversed input polarity. Connecting the battery with reversed polarity will damage the board. Double-check your connections before applying power.

4.3 Servo Output Voltage Selection

The SERVO PDB allows you to select the output voltage for your servos (Vx). The default output voltage 5V. Kushandura goho voltage:

Locate the small solder pads labeled Vx, 5V, 6V, 7.2V,uye 8.2V on the board (refer to Figure 1).
To select a voltage, bridge the Vx pad to the desired voltage pad (e.g., bridge Vx to 7.2V for 7.2V output). Use a small amount of solder to create a clean bridge.
Ensure only one voltage option is bridged at a time. Bridging multiple options or leaving none bridged may result in incorrect or no output voltage.

4.4 Servo Connection

Connect your servos to the output pins. Each servo typically requires three connections: Power (Vx OUT), Ground (G), and Signal.

The Vx OUT pins provide the selected regulated voltage to your servos.
The G pins provide the common ground for your servos.
The numbered pins (1-6) are for the servo signal lines, typically connected to your flight controller or receiver.
Use Dupont 2.54mm pins (included in packing) for secure connections if needed.

5. Operating Instructions

Once properly installed and connected, the SERVO PDB operates automatically. It will regulate the input voltage down to the selected output voltage for your servos.

Ensure all connections are secure before powering on your RC system.
Monitor your servo performance. If servos are sluggish or unresponsive, check the voltage selection and input power.
The board is designed to handle continuous loads of 4A and burst loads of 7A. Do not exceed these limits to prevent damage.

6. Kuchengeta

The SERVO PDB is a robust electronic component, but proper care can extend its lifespan:

Keep the board clean and free from dust, dirt, and moisture.
Regularly inspect solder joints and wire connections for any signs of wear, corrosion, or looseness.
Avoid exposing the board to extreme temperatures or direct sunlight for prolonged periods.
Do not attempt to modify the board beyond the specified voltage selection. Unauthorized modifications can void warranty and cause damage.

7. Kugadzirisa matambudziko

If you encounter issues with your SERVO PDB, consider the following troubleshooting steps:

Hapana Simba rinobuda:
- Tarisa kupinza voltage (Vbat IN) to ensure it is within the 5.5V to 36V range.
- Verify input polarity. Remember, there is no reverse polarity protection.
- Ensure the Vx output voltage selection pads are correctly bridged (only one option bridged).
- Check for any short circuits on the output side. The board is short-circuit tolerant for 3 seconds, but prolonged shorts can cause damage.
Incorrect Output Voltage:
- Re-check the solder bridge for Vx output voltage selection. Ensure it is clean and only bridging the desired voltage.
Servos Behaving Erratically/Weakly:
- Ensure the selected output voltage is appropriate for your servos.
- Check if the total current draw of your servos exceeds the 4A continuous or 7A burst limit.
- Inspect all servo connections for looseness or poor contact.
