General characteristics:
Depending on the current level, consists of a diode rectifier or of a half-controlled bridge, both in 6-pulse configuration.
A 12-pulse system can be configured by powering two SMB200s with parallel DC output via a transformer with two secondaries and 30° phase-shift.
For some lines or machines, the energy generated by motors powered by the DC Link system exceeds the level that the machine can reuse, and can be a high percentage of motorizing energy. In these applications, instead of using systems that dissipate energy to the resistance, it is more efficient to regenerate energy to the primary power supply. In this case, the SMB200 unidirectional power supply can be connected in parallel to an FFE200 regenerative power supply sized only for the regenerated power.
• Built-in fuses
• Selection of undervoltage limit via dip-switch based on line voltage
• Selection of line frequency: 50 or 60 Hz
• Selection of leveling capacitor precharge time via dip-switches.
