Consuming less than 0.21 Watt when no load is connected, AJM90 Series meets DOE's Level VI no load/standby power and active mode efficiency specification. AC-DC power supplies come in 3 models with outputs of 12, 18, and 24 Vdc and provide average efficiency of 89%, measured at 25, 50, 75, and 100% load. Sealed in IP32-rated enclosure measuring 0.86 x 5.5 x 2.7 in., 90 Watt power supplies operate in environments from 0–60°C with output power derating to 50% at 60°C.
