30W DC/DC converter is in a low profile, small footprint package
The 25.4 x 25.4mm (1.0 x 1.0 inch) low-profile DC/DC converter has two wide input ranges of 9.0 to 36V and 18 to 75V DC. Efficiency peaks at over 90%. The converter has 2kV/1 min isolation and requires no minimum load. A range of fully regulated single and dual outputs are available: 3.3V, 5.0V, 12V, 15V, 25V, ±12V, and ±15V DC.

The thermal and circuit design enable the parts operate to high ambient temperatures, for example to 80°C with no derating for the REC30E-4812SZ model. With derating and/or airflow, temperatures up to the case limit of 105°C are possible. High efficiency is maintained down to light loads for low standby losses. A shutdown control is included as well as a ±10% trim pin for single outputs.

Full protection is provided against over-temperature along with output short circuits, over-current, and over-voltage while the inputs are surge-rated to 50V and 100V for the two ranges.

Safety certifications are to IEC/EN 62368-1 and the converters comply with EMC standard EN 55032 class A without additional components and to class B with a simple external filter network. Reliability is typically over 500khrs according to MIL-HDBK 217F, GB at 25°C.

The REC30E-Z range with through-hole PCB mounting has a rugged metal casing and is encapsulated for use in Pollution Degree 2 harsh environments.

The converters are covered by a three-year warranty, and samples and OEM pricing are available from all authorised distributors or directly from Recom.
