DTEPU40A-102-104 are required to use AWG#14/4FT output cable.
DTEPU40A-105-110 are required to use AWG#18/4FT output cable.
DTEPU40A-111 is required to use AWG#20/4FT output cable.
The electrical characteristics will be changed by modified output cable.
The DTEPU40A-102 is available on NRCan mark
Output can provide up to peak load when the power supply starts up. Staying in more than rated load continuously is not allowed.
Each output is checked to be within voltage accuracy in 60% rated load condition.
Line regulation is defined by changing ±10% of input voltage from nominal line at rated load.
Load regulation is defined by changing ±40% of measured output load from 60% rated load.
Ripple & Noise is measured by using 20MHz bandwidth limited oscilloscope and terminated each output with a 0.47uF capacitor at rated load and
nominal line.
Hold up time is measured from end of the last charging pulse to the time which the main output drops down to low limit of main output at rated
load and nominal line.
Efficiency measured at rated load and nominal line.
