With the ability to operate over a wide input voltage range of 18 to 36 and 33 to 75 volts, these modules are ideal for use in battery backup applications common in today’s telecommunication and electronic data processing applications. The output is fully isolated from the input, allowing for a variety of polarity and grounding configurations. The VKA100xSC’s proprietary control circuitry responds to 50-100% load steps in 100mSeconds to within 1% nominal Vout. The patented fixed frequency architecture combined with surface mount technology results in a compact, efficient and reliable solution to DC/ DC conversion requirements.

TORQUE, 8 IN/LBS 2.28 [57.91] MAX OUTPUT ADJUST VOLTAGE OVP NOTE This feature allows the user to accurately adjust the module’s output voltage set point to a specified level. This is achieved by connecting a resistor or potentiometer from the TRIM terminal to either the +Vout terminal (for increased Vout) or the -Vout terminal (for decreased Vout). The formulae below describe the trim resistor value to obtain a Vout change of Δ%. VO is output voltage prior to adjustment (3.3V, 5V, 12V, 15V, or 24V). Radj - up = ( Radj - down = Vo(100 + Δ%) 1.225Δ% _ (100 + 2Δ%) Δ% Special attention should be given to the peak voltage deviation during a dynamic load step when trimming the output above the original set point to avoid tripping the overvoltage protection circuit. Should an OVP condition occur, the converter will go into a latch condition and must be externally reset before it will return to normal operation. ) kΩ (100Δ%- 2) kΩ Murata Power Solutions, Inc. 11 Cabot Boulevard, Mansfield, MA 02048-1151 U.S.A.
