SEPIC DC/DC Converter
12V DC to 9V-24V DC 100W
The Wondom PS-SP12159 is a SEPIC DC/DC converter (Single Ended Primary Inductor Converter), which converts a 12V DC DC voltage into an adjustable voltage via a DIP switch from 9V DC to 24VDC. To perform this conversion, this type of converter modifies the closing duty cycle of transistors.
The module is equipped with a status LED and has undervoltage and overload protection.
Voltage output selection
The module's DIP switch allows you to change the value of the output voltage from 9V to 24V DC. The table below details the different possible values and switch positions to be used. This table is also available on the back of the PCB.
