The Emerson/Astec SA202-3530 is a 200-watt power supply designed for industrial applications. It features an auto-ranging AC input that accepts 90-135 VAC or 180-265 VAC at 47-63 Hz. The unit is equipped with multiple outputs and offers protection against overvoltage and short circuits. Its design includes a self-contained fan for cooling and operates within an ambient temperature range of 0°C to +50°C, with a storage temperature range of -40°C to +70°C. The power supply boasts a high Mean Time Between Failures (MTBF) of over 100,000 hours at 75% load and 25°C ambient conditions. It complies with EMI/RFI standards such as FCC Part 15, Subpart B Class B and CISPR 22.
