* Read instruction manual carefully , before using the power supply unit.
* 1 : At maximum output power, nominal input voltage, Ta = 25°C.
* 2 : For cases where conformance to various safety specs ( UL, CSA, EN ) are required, to be described as 100 - 240VAC, 50 / 60Hz on name plate.
* 3 : Please refer to Output Derating Curve for input voltage less than 100VAC (next page).
* 4 : Not applicable for the in-rush current to Noise Filter for less than 0.2ms.
* 5 : Please refer to Fig A for measurement of line & load regulation, ripple and noise voltage.
* 6 : 85 - 265VAC, constant load.
* 7 : No load - Full load(Maximum power), constant input voltage.
* 8 : Current limiting with automatic recovery.
* 9 : OVP circuit will shutdown output, manual reset (Re power on).
*10: Measured by each measuring method of UL, CSA, EN.
*11: Refer to Output Derating Curve (CA729-01-02_) for details of output derating

Ripple and Noise
Ripple & noise are measured at 20MHz by using a 12'' twisted pair terminated with a 0.1uF and 47uF capacitor.
Avoid to operate at overload or dead short for more than 30seconds.
