DP100 Digital Power User Manual
Thank you for purchasing this product. We recommend that you spend some time
reading this user manual in order that you fully understand all the operational features
it offers.
Safety Instructions
1，The Type-C power supply range of DP100 is DC4.8V~36V. It will enter under voltage lockout
status and disable output when below 4.8V, and may be damaged when exceeds 36V ! It is
recommended to use 5V~32V power supply.
2，Ensure the input voltage is higher than output voltage, because DP100 working in Buck mode.
3，DC-TypeC cable is needed when use DC adapter for DP100. It is strongly recommended to
connect DC-TypeC cable to the DP100 first, then connect the DC adapter to DC-TypeC cable,
which can protect the Type-C interface and extend the service life of the interface.
4，When supplies power to inductive and capacitive loads, it is recommended to connect the load
first, and then turn on the DP100 output!
5，When the output is greater than 20V, please do not perform short-circuit test repeatedly,
otherwise the device may be damaged!
6，The negative terminal of the USB-A interface is GND, but the 4.0 banana plug output
negative terminal is not GND, so do not use it short-together.
7，When the output at high power mode, there will be a certain degree of heat, which is a normal
phenomenon. It is recommended to use it in a well-ventilated environment.
8，The Type-C power supply interface supports PD/QC protocol, and the default power supply
voltage is the highest voltage that the fast charger can supports.
9，Some PD fast charging heads have stricter requirements. If the input capacitor of DP100 is not
empty, it will causes a failure of protocol detection. In this case, unplug the power supply and
wait 3~5 min until the input capacitor of DP100 is fully discharged, then connecting it again.
10，When DP100 is used to charge batteries, it is strongly recommended to add an anti-backflow
module(eg. Schottky diode) at the output end to protect the device from damage!
