Circuit Topology: 330K Hz. Forward Circuit.  
Transient Response: Peak transient 150mV and recovers  
within 2mS after 25% load-change.  
Operating Temperature: -40 to +100°C (base plate)  
Power derating details please refer to the Derating Chart.  
Storage Temperature: -55 to +125 °C.  
Temperature Coefficient: ± 0.02%/°C.  
Humidity: Up to 95% RH, Non-Condensing.  
Cooling: At least 100LFM moving air is recommended for full  
load > +25°C room temperature in a confined area.  
Air flow vs. Power derating details, please refer to the  
Derating Chart.  
Safety Standard: IEC60950 Class II.  
Case: Aluminum base plate with metal standoffs.  
Power Density: 29-66 Watts / Cubic inch typical.  
Industrial Grade.  
NOTE: (1) All measurements are at nominal input, full load, and +25°C unless otherwise spec.  
(2) Line Regulation measured from High to Low Lines at full load.  
(3) Load Regulation measured from Full-Load (F-L) to Half-Load(H-L)at nominal input.  
(4) Correct fuse size by calculating the max. DC current drain at low Line input & adding 20-25% for desired fuse size.  
Due to requests in market and advances in technology, specifications subject to change without notice.
