Description

These digital power supplies are available in a range of output voltage 12V and 24V, continuous 24Watts output capability. They are packaged in an EI-57 standard UL 94V-0 plastic enclosure; plug is 3 prong US type. The AD24-12 & AD24-24 module are a series of isolated, Fly-back digital power supply that operate from a input range 85 to 265VAC (47~63Hz). Standard features include over current and short circuit protection. The efficiency is 80% minimum under 25% to 100% load condition. Typical applications include IT peripheral, home security data access system and other computing and communications equipment.

Part Number Selection

Absolute Maximum Ratings^*1

Note: 

*1. Use beyond the maximum rating may cause a reliability degradation of the power supply or may permanently damage the unit.

*2. Above humidity range to be defined under Non-condensing status

Input Specifications

Note:

*3. The inrush current is measured under normal input voltage (115/230VAC), cold start, 25^oC & full load condition

Output Specifications

Note:

*4 All specifications are defined under nominal input (120/230VAC), full load at 25 ^oC unless otherwise specified.

*5 Load regulation: by change the output load from 10% to 100% of rated load carries out the measurement.

*6 Line regulation: by change the line input from specified range, carries out the output measurement. With fixed rated load. 

*7 The ripple & noise is measured using 0-20MHz band width oscilloscope & terminated output a 10u/35V tantalum or MLCC X5R capacitor.

*8 di/dt = 0.5A/uS, Ta = 25 ^oC. with 10u/35V tantalum or MLCC X5R capacitor on output. 

General Specifications

*9. The efficiency η is average efficiency value where η=(η1+η2+η3+η4)/4, η1~η4 means the efficiency value under 25%,50%,75% & 100% load & normal input condition. 

*10. When short circuit or over current is activated, the power supply will go into Hiccup mode against short circuit or overload conditions and will recover once fault condition removed. 

*11. T ambient at 25^oC, rated load condition
