* Read instruction manual carefully , before using the power supply unit.
= NOTES=
* 1 : At Maximum Output Power, nominal input voltage, Ta = 25°C.
* 2 : For cases where conformance to various safety specs ( UL, CSA ) are required, to be described as 100 - 240VAC, 50 / 60Hz on name plate.
* 3 : Not applicable for the in-rush current to Noise Filter for less than 0.2mS.
* 4 : Ripple & noise are measured at 20MHz by using a 300mm twisted pair of load wires terminated with a 0.1uF film capacitor and a 47uF electrolytic capacitor.
* 5 : Measure line & load regulation at output terminal M3.5 tapped point.
* 6 : 88 - 264VAC, constant load.
* 7 : No load - Full load (Maximum power ), constant input voltage.
* 8 : Current limit with automatic recovery.
Avoid to operate at overload or dead short for more than 30 seconds.
* 9 : OVP circuit will shutdown output, manual reset (Re-power on).
* 10:
Measured by each measuring method of UL (at 60Hz), Ta=25°C.
* 11:
Refer to Output Derating Curve (PA583-01-02_) for details of output derating versus ambient temperature.
* 12:
All parameters NOT specifically mentioned are measured at 230VAC input, rated load and Ta = 25
