CMLV12S26-150 Wall Industries,Inc., CMLV12S26-150 Datasheet - Page 10

• Manufacturer Part Number: CMLV12S26-150
• Description: Low Voltage Dc-dc Chassis Mount Converter 10-36 Vdc Input 26vdc Output At 5.8a Half-brick Package
• Manufacturer: Wall Industries,Inc.

TEST SETUP:
The CMLV12S26-150 specifications are tested with the following configurations:
Regulation and Efficiency Setup
To ensure that accurate measurement are taken, the voltage measurements are taken directly at the terminal of the
module. This minimizes errors due to contact and trace lengths between the load and the output of the supply. The
following is a diagram of the test setup.
Output Ripple Voltage Setup
The module is tested with a 1µF ceramic capacitor in parallel with a 10µF tantalum capacitor across the output
terminals.
Input Reflected Ripple Current and Input Ripple Current Setup
The module is tested for input reflected ripple current (Irrc) and input ripple current (Irc). The input ripple voltage
is also measured at the pins with the following input filter. If there is a need to reduce input ripple current/voltage
then additional ceramic capacitors can be added to the input of the converter.
