Descripon: 
The PM1100 series of AC-DC switching power supplies in a package of 5.91 x 9.25 x 2.4 inches are capable of delivering 1100 was of 
connuous power. The units are constructed on a printed circuit board with an enclosed format for mechanical support and heat sinking. 
They are designed for medical applicaons including those needing BF rated insulaon and/ or an  operaon altude up to 5000 meters.  
 
Features: 
•  BF Class insulaon   
•  Operaon altude up to 5000 meters  
•  Compact size 5.91” x 9.25” x 2.4”  
•  Less than 300 μA leakage current 
•  EN55011 Class B conducted emissions  
•  Inhibit– TTL low to disable output  
•  Standard PS O and DC OK signals  
•  High Eciency 89% typical 
•  Compliant with RoHS requirements  
•  Standby output 5 VDC at 200 Ma 
•  Variable speed internal fan 
•  Overvoltage protecon  
•  Overcurrent Protec��on  
•  Thermal protecon

NOTES: 
1.  Peak current and power possible at 170-260 VAC input, 10 seconds, 35% duty cycle. 
2.  Ripple and noise is maximum peak-to-peak voltage value measured at output within 20 MHz bandwidth, at rated line voltage and 
output load ranges, and with a 10 μF tantalum capacitor in parallel with a 0.1 μF ceramic capacitor across the output.
