4 Input Voltage/

Current Range

¡

If you use a non-regulated power source for input, please check

and make sure that its voltage fluctuation range and ripple voltage

do not exceed the input voltage range shown in specifications.

¡

Please select an input power source with enough capacity, taking

into consideration of the start-up current (Ip), which flows when a

DC-DC converter starts up. Ip changes depending on the slope of

input voltage, load factor and the external capacitor. Please con-

tact us for details.

5 Cleaning

(except SUCOOC-C)

¡

If you need to clean the unit, please clean it under the following

conditions.

Cleaning Method: Immersion, Ultrasonic or Vapor Cleaning

Cleaning agent: IPA (Solvent type)

Cleaning Time: Within total 2 minutes for immersion, ultrasonic

and vapor cleaning

¡

Please dry the unit sufficiently after cleaning.

¡

If you do ultrasonic cleaning, please keep the ultrasonic output at

15W/ or below.

6 Safety Standards

¡

To apply for a safety standard approval using the power supply,

please meet the following conditions. Please contact us for de-

tails.

¿Please use the unit as a component of an end device.

¿The area between the input and the output of the unit is isolated

functionally. Depending upon the input voltage, basic insulation,

dual insulation or enhanced insulation may be needed. In such

case, please take care of it within the structure of your end-device.

Please contact us for details.

¡

Please use the following model names when you apply for a safe-

ty standard approval.
