Included 16AWG DC Input Cable
The package includes a 16AWG DC input cable designed to simplify connections between the converter and a compatible DC power source.
Three Convenient Ways to Connect Input Power
The BX-DD90M2-12V offers several input connection options for different DC power systems.
1. Direct DC Barrel Connector Input
The converter has a 5.5 × 2.5mm female DC input jack that accepts a compatible 5.5 × 2.5mm male DC power connector.
The input voltage must be between 10V and 30V DC, with center-positive polarity.
2. Connect Using the Included Input Cable
The supplied input cable has 5.5 × 2.5mm male connectors at both ends. It can connect a compatible female DC power output to the converter's input port.
3. Connect Using Bare Wires
For custom installations, one end of the included input cable may be cut to expose the two conductors for connection to a compatible DC power source.
Before connecting the wires, identify the positive and negative conductors and verify polarity with a multimeter.
Important Input Connection Safety:
Use only a compatible 10V–30V DC power source. Verify connector size, voltage, and polarity before connecting power. Incorrect polarity or excessive voltage may damage the converter. Bare-wire installations should use proper insulation and appropriate circuit protection.
Ultra-Compact Size and High Conversion Efficiency
The BX-DD90M2-12V combines a small physical size with efficient DC voltage conversion.
- Dimensions: 2.5 × 1.9 × 0.7 inches (63.5 × 48.9 × 16.9mm)
- Weight: 2.54 oz (72g)
- Conversion efficiency: Up to 95%
- Input voltage: 10V–30V DC
- Main output: Constant 12V DC, up to 6A
Why High Efficiency Matters
Power conversion efficiency is particularly important when using rechargeable batteries because energy lost during conversion reduces available runtime.
For example, when delivering 60W to a connected device:
- At 85% efficiency, the converter draws approximately 70.6W from the input power source.
- At 95% efficiency, the converter draws approximately 63.2W from the input power source.
Under these example conditions, the higher-efficiency converter uses approximately 7.4W less input power to deliver the same output.
Actual efficiency depends on input voltage, output load, and operating conditions.
Constant 12V DC Output and USB Charging
The converter provides a constant 12V DC output through its interchangeable output cable system. The included 12V cable is designed for compatible equipment requiring up to 6A.
The converter also includes a USB output for powering or charging compatible USB devices.
Installing the 12V Output Cable
The output cable has a special three-hole connector that attaches to the converter's output port.
- Disconnect the input power source before installing the output cable.
- Locate the three-hole connector at the end of the 12V output cable.
- Position the small flat surface of the connector facing upward toward the top of the converter.
- Carefully insert the connector into the converter's output port.
- Connect the other end to a compatible 12V device.
- Reconnect input power and verify normal operation.
Output Cable Compatibility:
The main DC output voltage is determined by the installed output cable. Use the included 12V output cable for 12V devices. Always confirm voltage and polarity before connecting electronic equipment.
Additional USB Charging Output
The built-in USB port provides an additional power option for compatible USB-powered electronics.
Published USB output modes include:
- 5V DC, up to 3A
- 9V DC, up to 2A
- 12V DC, up to 1.5A
The actual USB output voltage and current depend on the connected device and supported charging protocol.
The maximum combined power available when using the main DC output and USB output simultaneously is not specified. Do not assume both outputs can operate at their individual maximum ratings at the same time.
