Note: The D_T-W2/W5 series also are available in our company. APPLICATIONS The D_T-1W series are specially designed for applications where a group of polar power supplies are isolated from the input power supply in a distributed power supply system on a circuit board. These products apply to: 1) Where the voltage of the input power supply is fixed (voltage variation ≤±10%); 2) Where isolation is necessary between input and output (isolation voltage ≤1000VDC); 3) Where the regulation of the output voltage and the output ripple and noise are not COMMON SPECIFICATIONS Item Test condition Min.

During operation, make sure the specified range of input voltage is not exceeded, the DC DC Vo2 GND 0V2 Vo1 REG Vin 0V1 DC DC Vo2 REG GND 0V2 minimum output load could not be less than 10% of the full load. If the actual output (Figure2) 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 (D_T –W2/W5). 2) Recommended testing 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 (Figure1). 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).

The simplest method is to connect a self-recovery fuse in series at the input end or add a circuit breaker to the circuit. 5) Cannot use in parallel and hot swap The copyright and authority for the interpretation of the products are reserved by MORNSUN Specifications subject to change without notice.
