Make sure the specified range of input voltage is not exceeded, the minimum output load no less than 10% load. If the actual load is less than the specified minimum load, the output ripple may increase sharply while its efficiency and reliability will reduce greatly. If the actual output power is very small, please add an appropriate resistor as extra loading, or contact our company for other lower output power products. Recommended Circuit All the WRA_ZP-6W&WRB_ZP-6W Series have been tested according to the following recommended testing circuit before leaving factory. This series should be tested under load. Never be tested under no load (see Figure 1). DC DC Vin GND +Vout 0V C in Vin GND +Vout 0V Cin DC DC -Vout Dual Output Single Output (Figure 1) If you want to further decrease the input/output ripple, you can increase 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 sees (Table 1).

Input current of power supply should afford the startup current of this kind of DC/DC module (See figure 2), General: Ip ≤1.4*Iin-max Input Voltage (V) Input Voltage Range Ip No parallel connection or plug and play. |
