Oscilloscope Lin Cin Lin(4.7H) Current Probe DC DC Load Cin(220F, ESR < 1.0 at 100 KHz) DESIGN CONSIDERATIONS 1) Requirement on output load To ensure this module can operate efficiently and reliably, During operation, the minimum output load could not be less than 5% of the full load. otherwise ripple maybe increase dramatically. If the actual output power is very small, please connect a resistor with proper resistance at the output end in parallel to increase the load, suppose to use the resistance of 5% rated power, or use our company's products with a lower rated output power. 2) Recommended circuit All the WRA_ZP-3WR2 & WRB_ZP-3WR2 Series have been tested according to the following recommended testing circuit before leaving factory (see Figure 5). If you want to further decrease the input/output ripple, you can increase a capacitance properly or choose capacitors with low ESR. However, the capacitance of the output filter capacitor must be proper. If the capacitance is too big, a startup problem might arise. For every channel of output, provided the safe and reliable operation is ensured, the greatest capacitance of its filter capacitor must less than the Max. Capacitive Load.

Input current of power supply should afford the flash startup current of this kind of DC/DC module (Figure 6).
