| V VKA150MS24-205C OBSOLETE PRODUCTle Output Half Brick DC/DC Converter 150 Watt Sing O Watt Single g Contact Factory for Replacement Model RoHS Compliant 33 - 75V Input Range High Efficiency: 90% Typical 100S Transient Response 50 - 100% Load Step 420 kHz Fixed-Frequency Operation Remote Sense UL/CUL 1950, VDE EN60950 Operation to +100C Baseplate Temperature Primary Remote On/Off, Negative Logic Output Voltage Trim Continuout Short-Circuit Protection Thermal Shutdown Case Ground Pin The VKA150MS24-205C DC/DC converter presents an economical and practical solution for distributed power system architectures which require high power density and efficiency while maintaining system modularity and upgradeability. With the ability to operate over a wide input voltage range of 33 to 75 volts, this module is ideal for use in battery backup applications common in todays' telecommunication and electronic data processing applications. The output is fully isolated from the input, allowing for a variety of polarity and grounding configurations. The VKA150MS24-205's proprietary control circuitry responds to 50-100% load steps in 100Seconds 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. Safety approvals per UL/CUL 1950, EN 60950.

TORQUE, 8 IN/LBS 2.28 [57.91] MAX OUTPUT ADJUST VOLTAGE 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 %. VO is output voltage prior to adjustment. Radj - up = OVP NOTE 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. ( Vo(100 + %) 1.225% _ (100 + 2%) % ) THROUGH-HOLE SOLDERING INFORMATION These devices are intended for wave soldering or manual soldering. They are not intended to be subject to surface mount processes under any circumstances. The normal wave soldering process can be used with these devices where the device is subjected to a maximum wave temperature of 260C for a period of no more than 10 seconds. Within this time and temperature range, the integrity of the device's plastic body will not be compromised and internal temperatures within the converter will not exceed 175C. Care should be taken to control manual soldering limits identical to that of wave soldering.
