The AMESP350U-277JZ series is an efficient, enclosed, fan less, and semi-potted 350W ACDC power supply module. Offering a wide commercial input voltage range of 85-305VAC, output voltage ranges from 5-48V, 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 improved reliability and system safety. Additionally, it has operating altitude of 5000m. Furthermore, a high MTBF of 300,000h, output short circuit protection (OSCP), output over-current protection (OCP) and an output over-voltage protection (OVP) come standard with the series.

The AMESP350U-277JZ is great for street lighting controls, grid power, instrumentation, industrial controls, communication, and civil applications.
