This device was ordered by a company that used industrial robots for their projects.

One of the problems they faced was that they could not buy spare parts for their old robots and if they could, the cost would be very much. So, we designed a new switching power supply for them which costs about a tenth of the original one with the same functionality and also good reliability.

Its input is 3-phase 220VAC/50Hz and the output is 300VDC with a maximum current of 5A. The device has many protections like over-loading and overtemperature for critical situations. It also has a fault input which can disconnect the output as soon as a fault occurs.

We have made 3 copies of this device and since then all of them working properly without any problem.
