Explanations on Specifications

1. Input Voltage Range

Input voltage range is indicated below.

 

Take care not to apply input voltage which is above this specified 

range or under this specified range for more than 30 seconds. Nor should a DC input voltage be applied as 
this would result into power module damage.

Input Voltage Range : Single Phase 85 to 265VAC   Line Frequency Range : 47 to 63Hz

·

Basic Connection

Note)  To meet the surge immunity, evaluate the addition of the surge protection components.

Refer to separate document “PFE500F Series IEC Data”.
