4. Functional description 
4.1. Overview 
4.1.1. Input circuit 
The input circuit offers the following characteristics : 
• 
ac rectifying  
• 
EMI filtering 
• 
inrush current limiting, a walk-in circuit limits the output current 
rise to 25 A per second 
• 
low and high ac inhibit 
• 
power factor compensation 
• 
surge voltage protection 
• 
ac breaker for input protection 
For all input and output conditions specified in this manual, when the 
rectifier is turned on, the ac current will not exceed the maximum steady-
state value. 
4.1.2. Output circuit 
The output circuit offers the following characteristics : 
• 
shunt for output dc current sensing 
• 
225 A  dc circuit breaker for output protection
