320AMX-320AMXT
NOTES:
1. Rated output power is based on a combination of nominal output voltage, rated current and load power factor. Values stated represent the maximum capabilities of a given model (maximum power in split phase (Form2) direct
coupled mode is 1.3 kVA). Consult factory for assistance in determining specific unit capabilities as they might apply to your application.
2. Unit is operable as single phase with dual range capability or 3 phase. Output voltage range and 1/2/3 conversions are selected by front panel or bus commands.
3. Vmax is output voltage with nominal input and full rated load applied.
4. Available current will vary with output voltage and power factor. Current shown is per phase.

Short term overloads to 150% are permitted. Operating time
before thermal shutdown or circuit breaker trip varies from
seconds to several minutes depending upon line and tempera-
ture conditions.
