Description
Krones BSAB3000-480T-300C
Technical Specifications Three-phase 480V AC input; regulated DC output; rated output power 3000W; built-in input surge suppression; overvoltage, overcurrent and overtemperature protection; internal cooling fan; operating ambient temperature 0°C to +45°C; IP20 protection rating; DC output monitoring contact signal.
Functional Features Rectify and regulate three-phase AC input voltage to produce stable DC output for machine servo drives and control peripherals. Suppress voltage surges and transient spikes from factory power networks. Activate protection shutdown and send fault status signal upon overcurrent, overvoltage or internal overtemperature. Maintain output voltage stability under load fluctuation of packaging machine cyclic operation. Provide power good status feedback signal to the machine PLC.
Application Scenarios Beverage bottle filling machines, bottle labeling stations, container conveyor systems, packaging material handling machinery, Krones modular bottling production lines.
Performance Parameters Low output voltage ripple; fast load transient response; high power conversion efficiency; reliable protection action during overload and short-circuit events.
Material Composition Main power circuit PCB uses high-current FR-4 substrate; power conversion semiconductors include IGBT and diode rectifier modules; internal power magnetics are laminated iron-core inductors and transformers; enclosure is welded sheet metal with powder coating; cooling fan assembly has plastic impeller and ball bearings; internal insulating components use flame-retardant composite material.
Structural Characteristics Rack-mount metal chassis. Front panel has power status LED, fault indicator and air intake grille for cooling airflow. Rear terminal area separates three-phase AC input terminals and DC output terminals. Internal airflow path directs cooling air across power semiconductor heat sinks. Side mounting brackets secure the unit inside Krones machine electrical cabinet.
Working Principle Three-phase AC mains enters the input filter and rectifier stage to generate DC link voltage. The power conversion circuit regulates the DC link and delivers stabilized DC output to machine loads. Internal sampling circuits continuously monitor output current, output voltage and heat sink temperature. When operating parameters cross protection thresholds, the control circuit disables power conversion to protect the unit and downstream machine components.
Installation Requirements Mount the power supply unit on the designated mounting rails inside the Krones machine control cabinet. Connect three-phase 480V AC mains to input terminals and connect DC output cables to machine drive and control loads. Verify correct phase sequence and terminal torque after wiring. Power the unit on and test output voltage and power-good signal before machine commissioning.
Precautions for Use Maintain unobstructed inlet and outlet airflow for cooling fans. Confirm cable ampacity matches rated output current. Allow sufficient capacitor discharge time after power disconnection before touching internal terminals. Clean cooling fan and heat sink dust accumulation during regular machine maintenance.
