FAVOTEK MV10H Wide Voltage Isolated DC/DC Converter

Introduction: When you encounter the replacement value of the discontinued DC/DC module - MV10H

In the maintenance and upgrade of industrial control systems, measuring instruments, wireless network equipment, and telecommunications infrastructure, one of the most common thorny issues that engineers face is the sudden announcement of the discontinuation (EOL) of a critical DC/DC power module. Especially for modules that use non-standard pin arrangements, special output voltages, or wide input ranges (such as Woodward's isolated power supply, Vicor or Murata's old models), once the power supply is cut off, the cost of retrofitting the entire system may sharply increase. At this point, finding a substitute with electrical parameter compatibility, packaging standards, stable supply, and complete protection functions has become the top priority for hardware engineers and maintenance teams.

The MV10H series 10W DC/DC converter launched by FAVOTEK is an ideal solution designed to meet such demands. It adopts industry standard DIP 2 "× 1" metal packaging, providing a 2:1 wide input voltage range (5V/12V/24V/48V nominal input), single or dual output (3.3V to ± 24V), and has 1.5kV DC isolation, remote switch control, output voltage fine-tuning, and comprehensive electrical protection functions. This article will provide an in-depth analysis of the technical specifications, application circuit design, EMC rectification methods, and how to seamlessly replace discontinued modules of the MV10H series from an engineering perspective.

Replacement reminder: When the output voltage or current of the original module (such as discontinued Woodhead, Lambda, RECOM, etc.) is similar, priority should be given to selecting models with equivalent capacitive load capacity in MV10H. If a large number of electrolytic capacitors (e.g.>500 µ F) have been connected in parallel at the output of the original system, it is necessary to reduce external capacitors or add soft start circuits.

In depth interpretation of electrical specifications - the top ten parameters that engineers are most concerned about

3.1 Input voltage surge and starting voltage

The input voltage surge allowed by MV10H (lasting ≤ 1 second) is much higher than the normal operating range:

5V input model: Maximum 16 VDC

12V input model: maximum 25 VDC

24V input model: maximum 50 VDC

48V input model: maximum 100 VDC

This provides valuable tolerance for industrial sites with power transients, such as contactor action and motor start stop. The starting voltage threshold has been carefully designed to avoid frequent on/off during slight voltage drops.

3.2 Output voltage accuracy and load adjustment

Accuracy: Under any load (0%~100%), the output voltage error is typically ± 1%, with a maximum of ± 3%. For analog circuits with strict requirements (such as supplying ± 15V to operational amplifiers), an initial accuracy of 1% is sufficient and does not require additional calibration.
