*Read instruction manual carefully, before using the power supply unit.
NOTES :
* 1 : At 100VAC and Maximum Output Power, Ta = 25°C.
* 2 : For cases where conformance to various safety specs (UL, CSA & TUV) are required, to be described
as 100 - 240VAC, 50 / 60Hz on name plate.
* 3 : Please refer to Fig. A for measurement determination of line & load regulation and output ripple & noise voltage.
* 4 : From 85 - 265VAC, constant load.
* 5 : From Min load - Full load (Maximum power), constant input voltage.
* 6 : From 0 - +50°C, constant input voltage and load.
* 7 : Current limiting with automatic recovery. Avoid to operate over load or dead short for more than 30 seconds.
* 8 : Over Voltage Clamping by Zener Diode (on CH2 only).
* 9 : VDE class B with external capacitor. Measurement point for
output ripple & noise
