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 90-264VAC with output voltage options of 12, 24, 36, and 48VDC. All models also offer 4,000VAC input-to-output isolation and 1,500VAC output-to-ground isolation. Additional features include power factor correction, remote voltage sense, a 5V 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 76.2x127x35.1mm (3.00×5.00×1.38″) and provides an operating temperature range at full load from -40 to 50°C with forced air cooling, derating to 60% load at 70°C. Dimensions for the metal enclosed package measure slightly larger at 88x136x40.4mm (3.46×5.35×1.59″), while carrying an operating temperature range at full load from -40 to 60°C with forced air cooling, derating to 60% load at 80°C.
