Output specification
The following notes are applicable for the
power outputs.
1. Nominal current absorption is defining the nominal worst-case unit operating temperature. The nominal current absorption defines the maximum allowed component temperature for compliance according the safety requirements.
2. The tolerances include line and load regulations.
The ripple is a peak-to-peak value measured in
a bandwidth from 0 to 20 MHz.1. Nominal current absorption is defining the nominal worst-case unit operating temperature. The nominal current absorption defines the maximum allowed component temperature for compliance according the safety requirements.
2. The tolerances include line and load regulations.
The noise is a peak-to-peak value measured above 20 MHz.
3. Tested by dc loading side parallel with a 10 µF Electrolytic Capacitor and a 0.1 µF Ceramic Capacitor.
Power for Vamb only available when no power is requested on the Vbolton.
4. The input power will be less than 1 W at 230 Va c in this situation.
5. The maximum current is allowed for a period of 300 sec. The nominal current shall be the average current over any period of 3600 sec.

Power Down Signal (POWER_DOWN)
The unit will generate a POWER_DOWN signal when the mains input is removed. POWER_DOWN will go from high to low at least 15 ms before any of the output
voltages starts collapsing.
