Early in 2018, the new cost-effective AC/DC power supply module LDExx-20Bxx and LHExx-20Bxx single-output series were launched, after only half a year, the feedback from the market was quite good. This series of multi-output products (positive and negative dual output LHExx-20Axx, isolated dual output LHExx-20Dxx) was launched this month.

The product advantages are as follows:

1) Cost-effective, High Quality and Affordable.
Material normalization, production automation, higher product consistency and reliability, better performance and better price.

2) Better working temperature, higher isolation withstand voltage.
The operating temperature range is extended as -40°C to 70°C, and the high&low temperature section is less derated; the isolation voltage is increased to 4000VAC, which effectively improves the product reliability so as to protects the safety of the system.

3) High reliability and complete protection functions.
The Mean Time Between Failures (MTBF) of this series is >300,000h, and it is with the functions of output short circuit, over current and over voltage protection. It can reduce the power failure rate of the power supply and greatly improve the safety performance of the power supply and its load when the module power supply is abnormal.
