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
