D-NXT-2W Series
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 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
products with a lower rated output power (D-NXT-2W).
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.
Input Fuse Selection Guide
3) Recommended circuit
If you want to further decrease the input/output ripple , a capacitor filtering network may be connected to the input and output ends of the DC/DC
converter, see (Figure 2).
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) Output Voltage Regulation and Over-voltage Protection Circuit
The simplest device for output voltage regulation, over-voltage and over-current protection is a linear regulator and an capacitor filtering network with
overheat protection that is connected to the input or output end in series (Figure 3), the recommended capacitance of its filter capacitor sees (Table 1), linear
regulator based on the actual voltage and current to required.
5) Cannot use in parallel and hot swap
Note:
1. Operation under minimum load will not damage the converter; However, they may not meet all specification listed.
2. Max. Capacitive Load tested at nominal input voltage, full load and constant resistive load.
3. All specifications measured at Ta=25℃, humidity<75%, nominal input voltage and rated output load unless otherwise specified.
4. In this datasheet, all the test methods of indications are based on our corporate standards.
5. All characteristics are for listed model only, non-standard models may perform differently, please contact our technical person for more detail.
6. Contact us for your specific requirement.
7. Specifications subject to change without prior notice.
