Design & Feature Considerations
1. Input/Output Ripple Reduction
Reduce output ripple, it is recommended to use capacitors at the input/output.
It is recommended to use 10uF~100uF capacitors at the input; 47~220uF capacitors at the output.

2. Overload Protection
Tthe products provide protection against overload, the unit is equipped with internal current limiting circuitry .
3.Remote On/Off
To turn the power module off
Connect REM and -Vin,0V < Vrem < 1 v, Irem < 1mA;
To turn the power module on
1)Connect REM and +Vin,30V > Vrem > 5V;
2) REM pin is no connected.
4.Heat sinks
Make sure the products work well,recommend to use heat sinks.Products will not be suppliesd with heat sinks.
Note
1.All the specifications typical at Ta=+25 resistive load, nominal input voltage and rated output current unless otherwise noted.
2.Operation under no-load conditions will not damage these modules; however they may not meet all specifications listed.
3.Ripple & Noise measurement bandwidth is 0-20MHz.
3.Other input and output voltage may be available, please
4.All DC/DC converters should be externally fused at the front end for protection.
5.Specifications subject to change without notice
