These products apply to: 1) Where the voltage of the input power supply is wide range (voltage range 4:1); 2) Where isolation is necessary between input and output(isolation1500VDC); 3) Where the regulation of the output voltage and the output ripple noise are demanded. * Input voltage over it may cause permanent damage to the device. Note: The load shouldn't be less than 10%, otherwise ripple will increase dramatically. Operation under 10% load will not damage the converter; However, they may not meet all specification listed.

If the capacitance is too big, a startup problem might arise. For every 100 channel of output, provided the safe and reliable operation is ensured, the greatest capacitance of its filter capacitor sees (Table 1).

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. TRL Terminal When open or high impedance, the converter work well; When this pin is `high'; the converter shutdown; It should be note that the input current should between 5-10mA,exceeding the maximum 20mA will cause permanence damage to the converter. The value of R can be derived as follows: Input Voltage Range Input Voltage (V) No parallel connection or plug and play.
