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, or use our company ’s products with a lower rated output power. Recommended testing and application circuit If you want to further decrease the input/output ripple, an “LC” filtering network may be connected to the input and output ends of the DC/DC converter, see (Figure 1). Vin GND +Vo 0V DC Cin L L DC L Cout Cout -Vo L Vin GND +Vo 0V DC Cin L DC Cout Dual Output Sigle Output (Figure 1) It should also be noted that the inductance and the frequency of the “LC” filtering network should be staggered with the DC/DC frequency to avoid mutual interference. 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). EXTERNAL CAPACITOR TABLE (Table 1) Vin (VDC) Cin (uF) Single Vout (VDC) Cout (uF) Dual Vout (VDC) Cout (uF) 5 4.7 5 10 ±5 4.7 12 2.2 9 4.7 ±9 2.2 24 1 12 2.2 ±12 1 - - 15 1 ±15 1 It ’s not recommend to connect any external capacitor in the application field with less than 0.5 watt output. Output Voltage Regulation and Over-voltage Protection Circuit The simplest device for output voltage regulation, over-voltage and over-current protection is a linear voltage regulator with overheat protection that is connected to the input or output end in series (Figure 2). Vin GND 0V +Vout DC DC -Vout REG REG REG Dual Output Single Output Vin GND 0V +Vout DC DC REG REG (Figure 2) Overload Protection Under normal operating conditions, the output circuit of these products has no protection against overload. The simplest method is to connect a self-recovery fuse in series at the input end or add a circuit breaker to the circuit. No parallel connection or plug and play Note: 1.All specifications measured at Ta=25 °C, humidity<75%, nominal input voltage and rated output load unless otherwise specified. 2.Only typical models listed, other models may be different, please contact our technical person for more details. 3.Operation under minimum load will not damage the converter; However, they may not meet all specification listed. |
