Robust adjustable DC/DC converter

3 amp 12V to 9V DC/DC converter 5 Amp DC/DC step-down converters with the range of 3.5VDC to 35VDC input, user adjusable

These adjustable buck converters are regulated switching power converters (switchmode), designed to efficiently reduce the input voltage. They will take a wide range of input voltages, but the input voltage must be at least 0.6 volts higher than the output voltage. So you can output 12V, but the input voltage must be at least 12.6V.
The trim pot on the top surface is used to adjust the voltage, but specify what output voltage you want and we will adjust it before shipping.

Isolation

Common ground, the negative input is tied to the negative output. The frame is isolated.

Protection

Over temperature protection

If an extreme over temperature condition occurs the unit will shut down until the temperature is reduced.

Reverse polarity protection

Not reverse polarity protected

Overload protection 

If there is a short circuit connection or other overload connection is sensed, the unit will automatically limit the output current and, depending on severity, will go into a hiccup mode.
