## Long description

MPM-65-12ST is a compact AC/DC PCB-mount medical-grade power adapter delivering 65 W with a 12 V output and universal input range of 80–264 VAC. The supply is designed for installation in devices where small size and reliable low-voltage power are required; it meets medical safety standards with 2 x MOPP isolation and low leakage current, and its high efficiency and low no-load consumption support energy-efficient operation.
Advantages
The adapter offers high efficiency up to 93%, very low no-load power consumption (\<0.1 W) and full-range input for global use. Its compact, high-density design (approx. 87 x 52 x 29.5 mm per model specification) and robust dissipation enable space-saving integration. It provides reinforced isolation (4 kVAC) and medical-level safety (IEC EN60601-1 / ANSI/AAMI ES60601-1, 2 x MOPP), plus strong EMC performance and anti-vibration resistance.
Suitable for
 Low-voltage medical equipment requiring BF (patient contact) classification
 Compact medical devices and diagnostic instruments
 Industrial or laboratory electronics needing a stable 12 V, 65 W supply
