Brick  DC  Bus Power Supply

Brick  DC  Bus Power Supply

Most  smaller size(under 15A continuous current)  servoamplfiers require  DC BUS and 24V DC logic inputs. Machine builders
often  design their own.   Brick PS  eliminates this need and will save OEMs time and money, so engineers can  focus on more important tasks.

Brick PS is a multiaxis Power Supply module designed to deliver DC BUS and 24V DC logic to 1-4 servoamplifiers.
Low cost compact package, yet powerful module Brick conveniently delivers  DC BUS  power,  24V DC logic power and built in Shunt Regulator ( "Craw bar").

Features & Benefits

115/230V AC  Power input Single phase fuse protected
Four independent  170V DC DC BUS outputs, 20A total current
Four independent 24V DC outputs, 1A current
Shunt Regulator to absorb servomotor energy during regeneration, 300W
Convenient Phoenix connectors for each of the axis
Easy to see LEDs to indicate the mode of operations
Standard DIN rail mounting


Custom power rating and packaging per OEM specification
