Customer Question: I work in the robotics lab here at Stanford and have been using a few of your P1900 units on some of our robots to power PC''s from car batteries. They have worked flawlessly for over a year, so I''d like to
stick with your products.
I am building up a new robot that runs off a giant lithium battery pack. The pack discharges down to about 22 volts, and when sitting on the charger, the supply floats up to 36 volts. I would like to run a Mac Mini using one of your P2140 units. However, I saw that the upper voltage rating is 34 volts. Is there some margin in that rating, or is it a hard limit?
Answer: I would definitely drop the voltage. If you run the P2140 in over-voltage conditions (more than 26V) for longer than a short moment will probably case the P2140 to cut power to prevent any damage or fires.
