DC input voltage ranges

 

Input voltage ranges on DC-DC converters

Polyamp DC/DC converters use both very wide input as well as optimized for a specific input voltage (usually nominal battery voltage). In general a more optimized input voltage range result in higher power efficiency. Wide input ranges can be used in case the application has different input voltages to have less inventory. Another reason is that the application produces Cranking or Surges that must be handled e.g. vehicle applications, military, railway, especialy Diesel locos.

 

12 V

12 V input voltages

Is used mainly in car related applications or small mobile systems or in back-up systems. 12 V input voltage is handled by the A input voltage range 10-30 V or an input range coded 12 (11-16V).

Input range Family code
A = 10 - 30 Vd.c. PM50 PSE100 PSC150 PM150  PU300
12 = 11 - 16Vd.c.(*)

PM250 PU300 12/27


Polyamp guarantee full performance within the specified input range, which means 105% load capacity, 110% output voltage level at max rated operational temperature. 
A common question is if we can handle cranking down to 6 V. In general the converter switch off before 9 V, however will restart in a controlled manner.

Applications around 12V car systems are drowned by cheap and dirty converters as it is directed to consumers that usually do not use sensitive applications. A cigarette outlet supplied converter from good brand laptop manufacturer can kill a whole Police or Ambulance EMC environment. 

Polyamp deliver to Police and Ambulances, modified vehicles used aroud Swedish UN troops worlwide.
