The open frame VMS‑300A and metal enclosed VMS‑300A‑CNF series carry UL/cUL and TUV 60601-1 safety marks while meeting EN 55022 Class B and FCC Class B limits for radiated emissions. The series features a wide universal input voltage range of 90 to 264 Vac with output voltage options of 12, 24, 36, and 48 Vdc. All models also offer 4000 Vac input-to-output isolation and 1500 Vac output-to-ground isolation. Additional features include power factor correction, remote voltage sense, a 5 V standby, and remote on/off control as well as over voltage, over current, over temperature, and short circuit protections.

The open frame version of the VMS‑300A series measures 3.00 x 5.00 x 1.38 in (76.2 x 127 x 35.1 mm) and provides an operating temperature range at full load from -40 up to +50°C with forced air cooling, derating to 60% load at +70°C. Dimensions for the metal enclosed package measure slightly larger at 3.46 x 5.35 x 1.59 in (88 x 136 x 40.4 mm), while carrying an operating temperature range at full load from -40 up to +60°C with forced air cooling, derating to 60% load at +80°C.
