ABB 3BSE002348R1 SB511 Power Supply

SB511 3BSE002348R1 is positioned in a controller subrack to interface with the backplane bus and the battery. Mains supply is connected via a module front connector.

The mains supply input provides fusing and other adequate protection. The input energy is converted and used for a 5 V internal unit supply and by a controlled current generator for battery charging. The current generator produces a current adapted to the mode of operation: recharging, which takes approximately 10 hours after power-up, battery replacement, or trickle charging. During recharging, an LED FC on the module front lights up.

Diagnostic functions continuously supervise the operation. Error and other statuses are indicated by the module front LEDs. The information is available on the backplane for further processing by the system status functions.

 

SB511 Features:

Automatic Switching: Equipped with an automatic switching mechanism, it seamlessly takes over when the main power supply fails or is interrupted, providing reliable emergency power.
