APPLICATIONS

The B_(X)T-1W Series are specially designed for applications where a group of polar power supplies are isolated from the input power sup ply 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) Wh ere the regulation of the output voltage and the output ripple noise are not demanding. Such as: purely digital circuits, ordinary low frequency analog circuits, and IGBT power device driving circuits.

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. 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 (Figure 1). LSingle Output Vin GND +Vo DC Cin L DC Cout (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).

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 (Figure2). Vin GND Vin GND REG +Vout +Vout DC DC DCDC REG （Figure2） Overload Protection Under normal operating conditions, the output circuit of these products has no protection against over-current and short- circuits. 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.
