This power supply from IEI Electronics has an input of 90 to 130 V a.c. or 180 to 260 V a.c. (selectable), with maximum output power of 230 W at 30°C. It also has a power fault warning in that should one power module fail, a buzzer and LED will operate. After pushing the reset button, the buzzer stops and the LED will remain lighted until the failed power module is fixed.
The peak to peak ripple and noise for +5 V output is less than 50 mV, for ±12 V and -5 V output is less than 100 mV. Line regulation for each output is less ±1% while measuring at rated load and ±10% or 115 V a.c. or 230 V a.c. input voltage changing. The output voltage load regulation is less than the following values by changing each output and ±40% from 60% rated load, while keeping all other outputs at 60% rated load: +5 V, ±4%; +12 V, ±5%; -12 V, ±2%; -5 V, ±2%.
Efficiency is 70% typical and operating temperature is 0-50°C.
