Note: 1. *Under any conditions, the total power of the product should not exceed the rated power. When the output voltage is increased, the total output power cannot exceed the rated output  power, when the output  voltage is decreased, the output current cannot exceed the rated output current; 

2.  *When measuring the full load efficiency, the fan should be connected to an external power supply. Fan loss is not included in the input power. 

3.*MPOF Products with shell is also available. 

4. *25CFM refers the MPOF450-20BXX-C series external fan speed, forced air cooling 25CFM refers to the built-in fan speed, which automatically starts when the MPOF450-20BXX-CF series are turned on.

## **Note:** 

1. RS- and RS+ cannot be shorted or reversed, otherwise the power module will be damaged; 

2.  The remote compensation function can compensate the voltage drop on the output cable, which includes the sum of the cable drop connected to the output positive terminal and the output negative terminal; 

3. If you need to use remote compensation function, the signal pin needs to be connected with the load and with a twisted pair
