The AMES50-NZ is an AC/DC converter that offers much greater cost effectiveness due to material normalization and production automation also leading to improved reliability and performance. Offering a commercial input voltage range of 85-264VAC and an output voltage range from 5-24V, this series will offer many benefits to your new system design. This series offers great operating temperatures, from -30 ℃ to 70 ℃ and also features an isolation of 4000VAC for improved reliability and system safety. 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. **==> picture [124 x 18] intentionally omitted <==** **----- Start of picture text -----**
