Many computing systems based on X86 PC consume large current of 12V, when using powerful graphics card or other periperals such as FPGA or 3D scanner. To meet the requirement on large current of 12V output, PicoBox designed the X500 (X7-ATX) which has two independent buck controllers to generate two separated 12V output rails. X500 accepts 16-28V wide-range DC input and provides a cool, silent 500 Watts of power for small size PC designs. The PSU is compatible with an entire range of mini-ITX motherboards as well as regular motherboards.
You have the following three options to use X500.
- Use two separate DC sources for each of the two inputs on board. The second DC source is used specifically for generating the second 12V output rail.
- Use one powerful DC source for both the two inputs on board. You can connect the two inputs on board together and connect it to your DC input source.
- Use one powerful DC source for the 1st input on board. Just ignore the second input. There is no voltage on the 2nd 12V output rail for this case.
|Minimum Input Voltage
|Maximum Input Voltage
||+28.00V (over-voltage protecting occurs at +28.00V)
|Input Current Limit
|Reverse Input Protection
The recommended input voltages are 19V, 19.5V, 20V and 24V.
Maximum Power Characteristics
Forced air ventilation is required for load larger than 180 Watts. For fanless or improper ventilation operation, de-rate the output current of each rails by at least 30%.
