VRB0505S-5WR3
Mornsun VRB0505S-5WR3 isolated DC-DC converter, 5 W, 2:1 wide input, 5 V regulated output, 1500 VDC isolation in SIP.
The VRB0505S-5WR3 is a Mornsun VRB series isolated DC-DC converter module rated at 5 W with a 2:1 wide input range around a 5 V nominal input and a regulated 5 V output, in a compact SIP package. The wide input range lets the module accept a varying bus and still hold a regulated output, which suits battery-supplied, industrial and instrumentation designs where the rail is not tightly controlled. Galvanic isolation of 1500 VDC separates the input and output, which breaks ground loops and protects the control electronics, and the module includes input under-voltage and output short-circuit protection. The efficiency reaches about 72 percent with a low no-load power consumption, and the operating temperature range is -40 °C to +85 °C, which suits industrial equipment. The SIP package mounts directly on the printed circuit board, and the module meets the EN 62368-1 safety standard. Typical applications include industrial control, instrumentation, communication and medical equipment, and any design that needs an isolated regulated rail from a wide input. Every module 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 module, size the input and output capacitors and plan the EMC and thermal design.
FAE Professional Review
The VRB0505S-5WR3 is a good fit for a low-power isolated rail from a varying input, such as a battery or an industrial bus that is not tightly regulated. The 2:1 input range and the SIP package make it easy to design in, but keep the input and output capacitors close to the pins and follow the recommended filtering for EMC. It is one of the most frequently specified modules in our catalog.

Frequently Asked Questions
What projects suit the VRB0505S-5WR3?
It suits low-power designs that need an isolated regulated 5 V rail from a varying input, such as industrial control and instrumentation, battery-supplied systems and communication equipment. The 2:1 input range keeps the output regulated across the input swing.
For more power, use the 6 W URB module.
How do I handle EMC and filtering?
Keep the input and output capacitors close to the pins, add the recommended input filter for conducted emissions, and use a low-ESR capacitor where the ripple matters. The datasheet application circuit shows the recommended components.
Our FAE team can review your filtering.
