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
