1W to 3W Regulated DC-DCs with 1500Vdc Isolation

Mornsun launched the WRB dc-dc converter series, which features a 2:1 input range and has an operating temperature range of -40℃ to +85℃. It also offers a 1500Vdc isolation voltage. Mornsun contends that the dc-dc converter series is 40% smaller than general products.

With their compact size, the devices are suitable for communications, instrumentation, and industrial electronics applications.

WRB series converters also feature continuous short circuit protection that can ensure the safety performance of back-end circuits.

The converters have input voltages of 9V to 18V or 18V to36V. They have a Vout of 3.3V, 5V, 12V, 15V, and 24V depending on the model.

SMD and DIP packages are available. The SMD packages measure 14mm x 14mm x 9mm and the DIP package versions measure 15mm x 14mm x 9.1mm.
