mains conditions. These PCB-mount power supplies are rated to OVC III and/or PD3 conditions from
100-480VAC nominal input lines with phase-to-phase or single phase operation in class II installations
by just adding a single fuse externally. The modules support an operating temperature range from -40°C Single Output
to +80°C and come with fully protected outputs as well as EMC Class B compliance in floating output
connections. All these features make them an ideal fit for integration into smart grid, renewable energy,
smart metering and IoT applications.
