1200H series
Dual Output
DC/DC Converter
FEATURES
• Low Output Ripple and Noise
• 6 sided Continuous Shielding
• -40^oC to +75^oC Operating Temperature Range
• ±0.03% Line/Load Regulation
• Short Circuit Protection
• >1,000,000 Hours MTBF
DESCRIPTIONS
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.
