ABB IPSYS01 is a rack-mounted system power module for the Harmony Modular Power System II.
ABB IPSYS01 supplies 5 VDC, +15 VDC and -15 VDC operating voltages for rack I/O devices and 24 VDC field I/O power. It accepts 120 VAC, 240 VAC or 125 VDC input power.
The AC input stage uses active power-factor correction greater than 0.95, while current-sharing circuitry supports balanced operation of parallel system power modules. Verify input type, bus connections, cooling and current-sharing configuration before replacement.
