Transient recovery time is measured to within 1% error band for a step change in output load of 50% to 100% These power converters require a minimum output loading to maintain specified regulation, operation under no-load conditions will not damage these modules; however they may not meet all specifications listed. We recommend to protect the converter by a slow blow fuse in the input supply line. Other input and output voltage may be available, please contact factory. That “natural convection” is about 20LFM but is not equal to still air (0 LFM). Specifications are subject to change without notice.

Capacitor Cin, offsets possible battery impedance. Current ripple is measured at the input terminals of the module, measurement bandwidth is 0-500 KHz.

Copper Strip -Vin -Out Scope Cout Resistive Load Cout Scope Copper Strip Technical Notes Overcurrent Protection To provide protection in a fault (output overload) condition, the unit is equipped with internal current limiting circuitry and can endure current limiting for an unlimited duration. At the point of current-limit inception, the unit shifts from voltage control to current control. The unit operates normally once the output current is brought back into its specified range. Input Source Impedance The power module should be connected to a low ac-impedance input source. Highly inductive source impedances can affect the stability of the power module. In applications where power is supplied over long lines and output loading is high, it may be necessary to use a capacitor at the input to ensure startup. Capacitor mounted close to the power module helps ensure stability of the unit, it is recommended to use a good quality low Equivalent Series Resistance (ESR < 1.0 Ω at 100 KHz) capacitor of a 15μF for the 12V input devices and a 4.7μF for the 24V and 48V devices. + DC Power Source +Vin + +Out DC / DC Converter Load Cin - -Vin -Out Output Ripple Reduction A good quality low ESR capacitor placed as close as practicable across the load will give the best ripple and noise performance. To reduce output ripple, it is recommended to use 3.9μF capacitors at the output. + +Vin DC Power Source - +Out Single Output DC / DC Converter -Vin + Cout Load -Out +Vin DC Power Source - +Out Dual Output DC / DC Com. Converter -Vin -Out Cout Load Load Cout Maximum Capacitive Load The MKW1000 series has limitation of maximum connected capacitance at the output. The power module may be operated in current limiting mode during start-up, affecting the ramp-up and the startup time. For optimum performance we recommend 470μF maximum capacitive load for dual outputs and 2200μF capacitive load for single outputs. The maximum capacitance can be found in the data sheet. Thermal Considerations Many conditions affect the thermal performance of the power module, such as orientation, airflow over the module and board spacing. To avoid exceeding the maximum temperature rating of the components inside the power module, the case temperature must be kept below 90℃. The derating curves are determined from measurements obtained in a test setup.
