ZUS32405
COSEL ZUS32405 ZUS series isolated DC-DC converter, about 3 W, 24 V DC input and a regulated 5 V DC isolated output in a SIP board-mount package.
The ZUS32405 is a COSEL ZUS series isolated DC-DC converter rated at about 3 W that converts a nominal 24 V DC input into a regulated 5 V DC output, in a compact SIP package that mounts directly on the board. It provides an isolated output in a small footprint, so it suits a board that must derive an isolated low-power rail from a 24 V bus, such as a control interface, a sensor front end or a communication port, where the isolation protects the logic and breaks a ground loop. The converter provides a regulated output with protection and operates over an industrial temperature range, and the board-mount package keeps the design small. A small isolated converter is a common building block for a board-level rail, and the ZUS series covers the single-digit watts that an interface or a sensor needs, so a designer can add an isolated rail with a single part rather than a discrete design. Typical applications include industrial control, instrumentation, telecom and datacom boards, a distributed power system and a sensor or an interface that needs an isolated supply. 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.
FAE Professional Review
The ZUS32405 gives a small isolated 5 V rail at about 3 W from a 24 V bus, and its SIP package mounts directly on the board, so it suits a control interface, a sensor front end or a communication port that needs an isolated supply. Keep the input capacitor close and follow the recommended filter, and confirm the derating in a warm enclosure.

Frequently Asked Questions
What projects suit the ZUS32405?
It suits a board that must derive a small isolated 5 V rail at about 3 W from a 24 V bus, such as a control interface, a sensor front end or a communication port, where the isolation protects the logic and breaks a ground loop.
Confirm the power and the isolation.
How do I lay out a board-mount converter?
Keep the input capacitor close to the converter, follow the recommended input filter for the emissions and keep the switching loop small. Use a ground plane and keep the isolated output away from the input to preserve the isolation.
Our FAE team can review the layout.
Is the converter genuine and documented?
BeiLuo supplies factory-traceable ZUS32405 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.
