The AMEL20-277HAVZ series is an efficient 20W AC-DC power supply module. Offering a commercial input voltage range of 85-305VAC, output voltage ranges from 3.3-24V, low power consumption, high efficiency, high reliability and safer isolation. 

This new series offers great operating temperatures, from -40°C to 85°C with full power up to 50°C and features an isolation of 4000VAC with OVC III for improved reliability and system safety. Furthermore, a high MTBF of 285,000h, output short circuit protection (OSCP), output over-current protection (OCP) and an output over-voltage protection (OVP) come standard with the series. 

The AMEL20-277HAVZ is suitable for grid power, industrial instrumentation and controls, communication, and civil applications.
