The Recom R1DX dual-output,isolated DC/DC converters are available from Dengrove Electronics Components

The open-frame, surface-mount power modules offer a choice of ±5.0, ±9.0, ±12 or ±15V bipolar outputs.

They are compact, measuring just 15.2 x 10.7mm and 8.0mm high. They are capable of driving capacitive loads of up to 1000µF, for applications such as RS-232 bus isolation, and for providing bipolar power to isolated DACs, sensors, op-amps, and general industrial automation, control, and test and measurement equipment.

They are energy-efficient and easy to design-in, claims Dengrove. With no minimum-load requirement, the converters consume less than 150mW quiescent power and operate over a temperature range of -40 to 100°C at full load without derating.

The modules are certified in accordance with the latest safety standard, IEC/UL/EN 62368-1, as well as the one it will supersede, 60950-1. This helps OEMs transition products to the new standard. Built-in isolation is rated at 1kVDC/1s, and the alternative /H version provides even higher isolation of 3kVDC/1s.

For EMC compliance, adding only an input capacitor satisfies Class A requirements or a simple low-cost LC filter for Class-B equipment.
