Modular 3-Phase UPS Cabinet

The CyberPower SM020KAMFA is a 20000 VA and 20000 W double-conversion online UPS designed for three-phase environments. It supports configurable N+X redundancy and accepts 208/120V or 220/127V input and output. The 11U rackmount cabinet houses hot-swappable power modules for scalable capacity from 10 to 20 kW.

Hardwire Terminal Block Output

The unit provides a single hardwire terminal block for permanent electrical installation rather than plug-in outlets. This connection method suits data centres and industrial facilities where loads are wired directly to distribution panels. The output voltage is configurable between 208/120V and 220/127V to match local three-phase distribution.

Sustained Overload Behaviour

Under continuous load the UPS tolerates 110% for 10 minutes, 125% for 1 minute and 150% for 30 seconds before protection activates. Loads above 150% are limited to 200 milliseconds. The sine-wave output maintains a 1.0 power factor throughout these ranges, delivering full rated watts without derating during extended overload events.

Questions about this item

What does the 20000 VA / 20000 W rating mean when the UPS is installed in a rack?

The unit delivers 20000 VA apparent power and 20000 W real power simultaneously because its power factor is 1.0, so the full VA capacity is usable for actual load.

What interface ports are built in and what management limits do they impose?

It provides RS232 and RS485 serial ports plus USB, Modbus, SNMP and EPO connections; PowerPanel Business software manages monitoring and shutdown across the network.

How much rack height and depth does the 11U cabinet need for mounting?

The chassis occupies 11 rack units and measures 23.9 inches wide, 19.1 inches deep and 30.5 inches high, weighing 133.8 lbs for structural planning.
