Hi All,
I am working on a home project that needs to supply a 24V power to a brushless motor controller. The motor draws 24V with current less then 3.0A and my 12 to 24V DC to DC power supply is rated 700W. But when I connect the things together, the power supply will shut it down. My guess is the motor controller draws a high current at a very short time that overwhelmed the power supply, since my current meter indicated only 3 A from the 12V side.
Can anyone give me a suggestion how to make my power supply work? Can I add a large capacitor at the power supply output? I also tried an other DC 2 DC (rated 4.5A output) power supply. The result is even worse. (It worked for a few seconds vs. minutes). My application is a mobile one and I can't use a desktop power supply. The power source is from 12V lead acid battery. Any solution to my problem?
Thanks in advance.
