*Read instruction manual carefully, before using the power supply unit. Derating Curve
=NOTES=
*1. At 100VAC/200VAC and maximum output power.
(Baseplate Temperature = +25°C.)
*2. For cases where conformance to various safety specs
(UL, CSA, EN) are required, input voltage range
will be 100 - 240VAC(50 - 60Hz).
*3. Ratings - refer to Derating Curve on the right.
*4. Heatsink has to be chosen according to Instruction manual.
*5. External components are needed for operation.
(Refer to basic connection and instruction manual.)
*6. First inrush current. Not applicable for the inrush current to
Noise Filter for less than 0.2ms.
*7. Refer to Instruction manual.
*8. Ambient Temperature min=-40°C.
*9. Start-up at Vin=83VAC guaranteed.

==NOTES==
*1. Use an external fuse of fast blow type for each unit.
*2. The allowable ripple current of capacitor must be more than 3A(rms).
*3. Put this capacitor near the terminal as close as possible.
*4. The maximum capacitance that can be used is less than 1200uF(Rated capacitance).
Avoid the connection of capacitance which is more than above, else it will lead to
module to damage.
*5. The inrush current at AC throw in can be suppressed by the external Resistor
(Built-in thermal fuse) connected between the R and +BC terminals.
*6. If the ambient temperature is less than -20°C, use twice the recommended capacitor above.
*7. Refer to instruction manual for further details.
