COSEL DC-DC Converter Distributor | CBS and ZUS Series
Genuine COSEL isolated DC-DC converters, the CBS open-frame and ZUS board-mount families, for telecom, industrial and distributed power designs.
COSEL DC-DC Converters Overview
BeiLuo supplies genuine COSEL DC-DC converters, the isolated modules that convert one DC rail into another for a distributed power system, a telecom board or an industrial instrument. A COSEL DC-DC converter provides an isolated, regulated output from a DC input, so it breaks ground loops, protects the load from the source and meets the isolation that a telecom or an industrial standard requires. The CBS series is an open-frame isolated converter in the tens of watts, and the ZUS series is a compact isolated converter in the single-digit watts for a board-mount design, so a designer can power a small load or a larger rail from the same supplier. The devices cover a range of input and output voltages, provide a regulated output with protection, and operate over an industrial temperature range, and the isolation separates the primary and the secondary for safety and noise immunity. Typical applications include telecom and datacom boards, industrial control, distributed power architecture, instrumentation and a DC-powered system. Every converter BeiLuo ships is factory-traceable and includes an import declaration, a certificate of origin and a RoHS compliance file. Our FAE team helps you choose the power, the input and output voltages and the isolation and plan the layout and the filtering.

Frequently Asked Questions
How do I read the COSEL DC-DC table?
Power sets the output wattage, Input the DC source, Output the regulated voltage, Isolation the separation and Package the mounting.
Match the input to your bus and size the power with margin.
When do I need a DC-DC converter?
Use a DC-DC converter to create an isolated or a different rail from an existing DC bus, such as a 5 V rail from a 24 V bus, or to break a ground loop in a telecom or an industrial board. The isolation protects the load and improves the noise immunity.
Our FAE team can help choose the converter.
How do I plan the input filtering?
A DC-DC converter reflects a ripple current onto the input, so keep the input capacitor close and add the recommended filter for the conducted emissions. Follow the datasheet application circuit and keep the switching loop small.
Our FAE team can review the layout.
Are the converters genuine and documented?
Every COSEL converter BeiLuo ships is factory-traceable and includes an import declaration, a certificate of origin and a RoHS compliance file. Mainstream models are held in regional warehouses.
