CBS1002405
COSEL CBS1002405 CBS series isolated DC-DC converter, about 100 W, 24 V DC input and a regulated 5 V DC isolated output in an open-frame package.
The CBS1002405 is a COSEL CBS series isolated DC-DC converter rated at about 100 W that converts a nominal 24 V DC input into a regulated 5 V DC output, in an open-frame package that mounts on a board or a chassis. It provides an isolated output, so it breaks the ground loop between the source and the load and protects the load from the source, which suits a distributed power architecture, a telecom board or an industrial instrument where a lower rail must be derived from a 24 V bus. The converter provides a regulated output with protection for over-current and over-voltage, and it operates over an industrial temperature range with a good efficiency, and the open-frame construction allows the heat to spread to the host board or the mounted surface. A DC-DC converter is the building block of a distributed power system, and the CBS series covers the tens of watts that a board-level rail needs, so a designer can power a 5 V logic load from a 24 V industrial or telecom bus with a single isolated part. Typical applications include telecom and datacom boards, industrial control, distributed power architecture and instrumentation. 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 and the isolation and plan the layout and the filtering.
FAE Professional Review
The CBS1002405 gives an isolated 5 V rail at about 100 W from a 24 V bus, which is a common distributed-power building block for a telecom or an industrial board. The open-frame body relies on the host board or the mounting surface for cooling, so provide a good thermal path. Keep the input capacitor close and follow the recommended input filter for the emissions.

Frequently Asked Questions
What projects suit the CBS1002405?
It suits a board or a system that must derive an isolated 5 V rail at about 100 W from a 24 V bus, such as a telecom board, an industrial control card or an instrument in a distributed power architecture.
Confirm the power and the isolation.
How do I cool an open-frame converter?
An open-frame converter spreads its heat into the host board or the mounted surface, so provide a good thermal path and enough copper area, and allow the air to move around it. Confirm the derating at the highest ambient.
Our FAE team can review the thermal design.
Is the converter genuine and documented?
BeiLuo supplies factory-traceable CBS1002405 converters with an import declaration, certificate of origin and RoHS file on every order. Stock is normally available and the datasheet downloads from this page.
