AHE28XXS Series
Specifications
T
CASE
= -55°C to +85°C, V
IN
= +28V
±
5% unless otherwise specified
Input Voltage
Power Output Internally limited, 17.5W typical for AHE2805S, 22.5W typical for AHE2812S and AHE2815S
Soldering 300°C for 10 seconds
Temperature Range
Storage -65°C to +135°C
Notes to Specifications
1. Above +85
°
C case temperature, derate output power linearly to 0 and maximum input voltage linearly to 42V at 115
°
C case.
2. Recovery time is measured from the initiation of the transient to where V
OUT
has returned to within
±
1% of V
OUT
at 50% load.
See typical waveforms.
3. Turn-on delay time measurement is for either an application of power at the input or a signal at the shutdown pin.
4. For operation at 16VDC, derate output power by 33%.
