Using remote sense with long wires may cause output voltage to become unstable. Consult us if long sensing wiring is necessary. 2. Sense tracks or wires should be as short as possible. If using wires, it should not use twisted-pair or shielded wires. 3. Please use wide PCB tracks or a thick wires between the power supply module and the load, the line voltage drop should be kept less than 0.3V. Make sure the power supply module's output voltage remains within the specified range. 4. The impedance of wires may cause the output voltage oscillation or a greater ripple, please take adequate assessments before using. Design Reference 1. Typical application If not using Momsun's recommended cicuit, please ensure an 220F electrolytic capacitors in parallel with the input, which used to suppress the surge voltage come from the iuput terminal. All the DC/DC converters of this series are tested according to the recommended circuit (see Fig. 1) before delivery. If it is required to further reduce input&output ripple, properly increase the input & output of additional capacitors Cin and Cout or select capacitors of low equivalent impedance,provided that the capacitance is no larger than the max. capacitive load of the product.
