Wide 10V–30V DC Input
Unlike fixed-input DC adapters, the DD90X-TB accepts a wide
10V to 30V DC input range. This makes it useful with
many different DC power sources, including compatible battery packs and
12V, 16V, 19V, and 24V power systems.
elect the Output Voltage You Need
A voltage-selection switch on the converter allows you to select the
appropriate output voltage for your equipment. Available settings include
12V, 15V, 16V, 18.5V, 19.5V, 20V, and 24V.
Important — Set the Output Voltage Before Connecting Your Device
Select the correct output voltage before connecting the
converter to the input power source and your device. If you need to change
the output voltage, disconnect the converter from both the input power
source and output device first.
Do not change the voltage setting while the converter is connected
to a power source or powered device.
Always check the voltage requirement printed on your device or its original
power adapter before selecting the converter output voltage. Using an
incorrect voltage may damage your equipment.
Up to 90W DC Output
The DD90X-TB provides up to 90W maximum output power,
making it suitable for many laptops and other medium- to high-power
DC devices.
Built-In 5V USB Power Port
In addition to the selectable DC output, the DD90X-TB includes a
5V USB port for powering or charging compatible
USB devices. USB charging cable is not included.
Compact and Portable
The DD90X-TB measures approximately
4.5 × 2 × 1.2 inches and weighs approximately
0.55 lb (260 g). Its compact design makes it easy to
carry with a laptop, portable battery, mobile workstation, or other
DC-powered equipment.
Three Ways to Connect to Your DC Power Source
The DD90X-TB uses a 5.5 × 2.5mm female DC input.
The included input cable provides flexible connection options for
different DC power sources.
1. Direct DC Plug Connection
Connect a compatible 5.5 × 2.5mm male DC plug from
your DC power source directly to the converter's female input connector.
2. Male-to-Male DC Cable Connection
When your battery or power source has a 5.5 × 2.5mm female output port,
use a compatible 5.5 × 2.5mm male-to-male DC cable
to make the connection.
3. Direct-Wire Connection
For applications requiring a direct connection to a suitable DC power
source, the connector on one end of the input cable may be removed and
the wires connected directly to the power source.
Red wire = Positive (+)
Black wire = Negative (–) / Ground
IMPORTANT — Observe Correct Polarity
Positive (+) on the converter must connect to Positive (+) on the
power source.
Negative (–) on the converter must connect to Negative (–) on the
power source.
Reversing the polarity may damage the converter and/or connected equipment.
Important Information for High Output Power Use:
This converter accepts a wide input voltage range of 10V–30V DC, providing flexibility for use with a variety of DC power sources. For high-power applications that require high output power from the converter, it is recommended to use a higher-voltage input power source whenever possible. A lower input voltage requires higher input current to produce the same output power.
When using a lower-voltage power source, such as 12V, high-power output may require a very high input current, which can cause the input connector and connection point to become hot. Please monitor the input connection during high-power operation. If the input connector becomes excessively hot, stop using the device immediately.
Optional Connector Tips for More Devices
The standard DD90X-TB output cable uses a
5.5 × 2.5mm male barrel connector. For equipment
requiring a different DC connector size, an optional
12-piece connector-tip kit and other BiXPower
C-series connector tips are available.
