INPUT CHARACTERISTICS  
DESCRIPTIONS  
Unit/Comments  
Min Typ Max  
The 1200H series 12 watts, low noise high density DC/DC  
converters offer a wide variety of input voltages in 5, 12, 18,  
24, 28 and 48 VDC with high performance output characteris-  
tics. The low profile modular case (2.0” X 2.0” X 0.4”) makes  
the 1200H series attractive for printed circuit board mounting  
applications for I/O computer subsystems, instruments,  
telecommunication equipment, medical and analog  
networks where low noise output and excellent line and load  
regulation is required.
