Attenuator Assembly for use with 8902-LS-00 only LA471892U001 for 890 AFE application.
The Line Synchronization Option allows the 890 Active Front-End (AFE) to monitor the threephase
supply voltage waveform and synchronize the IGBT firing to supply grid frequency and
phase rotation. Once synchronized, the AFE acts as a four-quadrant, sinusoidal, power factor
controlled power supply.
Part Number for the Attenuator module part
number is LA471892U001.
• The attenuator module provides a means to
drop the line voltage to SELV levels.
• Its output has two components, coding (supply
phase zero crossing) and rotation (supply phase
rotation), which are sent to the 8902-LS-00
• Enables the 890 AFE to execute power factor
and VAR control.
