Oscilloscope Lin Cin Lin(4.7µH) Current Probe DC DC Load Cin(220µF, ESR < 1.0Ω 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 is not less than 10% of the full load. 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. 2) Overload Protection Under normal operating conditions, the output circuit of these products has no protection against overload. The simplest method is to add a circuit breaker to the circuit.

It should also be noted that the capacitance of 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 recommended capacitance of its filter capacitor sees (Table 1).

It’s not recommended to connect any external capacitor in the application field with less than 0.5 watt output. 4) The input and the output of the product are recommended to be connected to ceramic capacitor or electrolytic capacitor. Using tantalum capacitor may cause risk of failure 5) It is not recommended to increase the output power capability by connecting two or more converters in parallel. The product is not hot-swappable Note: 1. Operation under minimum load will not damage the converter; However, they may not meet all specifications. 2. Max. Capacitive Load is tested at nominal input voltage and full load. 3. Unless otherwise noted, All specifications are measured at Ta=25°C, humidity<75%, nominal input voltage and rated output load. 4. In this datasheet, all test methods are based on our corporate standards. 5. All characteristics are for listed models, and non-standard models may perform differently.
