The ABB 6644424A1 serves as a voltage bus monitor assembly within the Harmony Rack Power System (MPS3). This component monitors the voltage levels of +5VDC, +15VDC, -15VDC, and MCOM on the system bus bar. If any of these voltages fall out of tolerance, the monitor generates a low true signal called PF1. Notably, the 6644424A1 consumes low input current, drawing less than 50mA. It is housed in a compact enclosure suitable for easy DIN rail mounting.
