Use only the same capacity power module in the chassis. Do not mix different capacity power modules.
Note
High-Voltage AC / DC Power Supplies
HVAC/HVDC power modules operate in the input range of 180 VAC to 305 VAC (nominal input level of
200 to 240 VAC, 277 VAC) and 192 to 400 VDC (nominal 240 VDC, 380 VDC).
• PSU6.3KW-20A-HV: Each 6.3 KW, 20A power module can supply up to 6.3 KW to the power tray
when it’s supplied by two feeds (A and B). It can supply up to 3.15 KW with only one feed.
• PSU6.3KW-HV: Each 6.3 KW, 30A power module can supply up to 6.3 KW to the power tray when
it’s supplied by two feeds (A and B). It can supply up to 4.8 KW with only one feed.
