It features an ultra-wide wide, 85-305VAC input range accepting either AC or DC voltage, high reliability and low power consumption. All models are particularly suitable for industrial controls, electric power, instrumentation, smart home applications and other applications requiring UL/CE certifications and that have low EMC requirements. We recommend using external components as shown in the recommended application circuit for enhanced EMC performance in harsh environmental conditions. **==> picture [100 x 18] intentionally omitted <==** **----- Start of picture text -----**
