Scope measurement should be made by using a BNC socket, measurement bandwidth is 0-20MHz. Position the load between 50mm and 75mm from the DC/DC converter. +Out -Out +Vin -Vin Resistive Load Scope Copper Strip Cout Copper Strip Single Output DC/DC Converter +Out -Out +Vin -Vin Resistive Load Scope Copper Strip Cout Com. Scope Cout Copper Strip Copper Strip Dual Output DC/DC Converter TEST SETUP 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 < 1.0Ω at 100 KHz) capacitor of 2.2µF for the 5V input devices and a 1.0µF for the 12V input devices. + +Out -Out +Vin -Vin DC/DC Converter Load DC Power Source + - Cin Output Ripple Reduction A good quality low ESR capacitor placed as close as possible across the load will give the best ripple and noise performance. To reduce output ripple, it is recommended to use 1.5µF capacitors at the output. +Out -Out +Vin -Vin Load DC Power Source + - Cout Single Output DC/DC Converter +Out -Out +Vin -Vin Load DC Power Source + - Cout Com. Load Cout Dual Output DC/DC Converter Maximum Capacitive Load The LANE-6KV series has a limitation of maximum connected capacitance on the output. The power module may be operated in current limiting mode during start-up, affecting the ramp-up and the start-up time. For optimum performance we recommend 220µF maximum capacitive load for dual outputs and 680µF capacitive load for single outputs. The maximum capacitance can be found in the Model Selection Table. 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°C. The derating curves are determined from measurements obtained in a test setup. DUT Position of air velocity probe and thermocouple 50mm / 2in Air Flow 15mm / 0.6in |
