RPA100H-RUW
Description
The half-brick RPA100H series DC/DC converter is designed for railway rolling stock and high voltage
battery applications. It has a 10:1 input voltage range to cover all input voltages from nominal 24VDC
up to 110VDC in a single product (including EN50155 transients) and offers isolated and regulated
12V, 15V, 24V or 48VDC outputs. The converter has a consistently high efficiency over the entire
input voltage range and comes with a metal baseplate to permit a wide operating temperature range
from -40°C to +97°C (when baseplate cooled). The case is fitted with threaded inserts to allow
secure mounting to the PCB or bulkhead for use in high shock and vibration environments.
The converter is certified to UL/IEC/EN60950 and comes with a three year warranty.

Input Voltage Range
The RPA100H series has an adjustable under voltage lockout which will shut down the
converter according to following settings.
Continuous full power operation is rated between 16.5V and 140V,
including full load start-up.
Once running, the converter will operate for short periods of time over
an extended input voltage range down to 14.4V and up to 156V, thus
covering all EN50155 under-voltage and over-voltage transient
conditions.

Output Voltage Trimming
RPA100H-RUW converters offer the feature of trimming the output voltage over a certain range around the nominal value by using external trim resistors.
The values for trim resistors shown in trim tables below are according to standard E96 values; therefore, the specified voltage may slightly vary; they also
can be calculated with below shown equation.
Practical Example RPA100H-12SRUW trim up +10% Practical Example RPA100H-12SRUW trim down -8%
Calculation:
Rdown =Vref - R1
