1. The CTRL pin voltage is referenced to GND.

Note:

Example:

1. Min. load shouldn‘t be less than 5%, otherwise ripple maybe increase

dramatically. Operation under minimum load will not damage the converter,

however, they may not meet all speciﬁcation listed.

50 = 50Watt; D = DIP; A = series; W = wide input (2:1); 24 = 18-36Vin;

15 = 15Vout; S = single output; 1.5 = 1500VDC isolation

2. Max. Capacitive Load tested at input voltage range and full load.

3. All speciﬁcations are measured at TA = 25°C, 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 corporate

standards.

5. All characteristics are for listed model, non-standard models may perform

diﬀerently, please contact our technical person for more detail.

If it is required to further reduce input and output ripple, properly incre-

ase the input & output of additional capacitors Cin and Cout or select

capacitors of low equivalent impedance provided that the capacitance

is no larger than the max. capacitive load of the product.
