Beijing Qizheng Design Technologies Co. Ltd's DIL series of dc/dc converters operates from an 18V to 36V or 36V to 72V input and delivers 5V or 12V output with an efficiency >75 percent, enabling it to be used in industrial control computers, meters, medical apparatus, and telecom equipment.

Output current is measured between 0.25A and 1A, while insulation voltage is 500Vdc between input and case or output and case. The converters also feature an n-type filter to reduce conduction noise and a sealed construction to reduce EMI and RFI.

The converters have a maximum insulation capacitance of 7nF and a switching frequency of 300kHz. They are rated for operation over the -550C to 850C temperature range.
