AC Input Ratings
Voltage: Nominal 208/240 volts AC, single phase, 50/60 Hz, with an operating range
of 176 to 264 volts. Acceptable input frequency range is 45 to 65 Hz.
Safe Voltage: The system can tolerate 415 volts AC without damage.
Harmonic Content (THD): < 5% THD at 50% - 100% load. The voltage source
must have a voltage THD of < 1.1%.
The Rectifier complies with EN61000-3-2.
Inrush Current: Peak does not exceed 1.5 times the steady state peak value of the
input current at full load, nominal input voltage, and for any duration of AC input
interrupts. Under the above conditions, standard AC distribution circuit breakers will
not trip.
Typical Input Data (1R483200): 60 Hz input.
a) System output is initially adjusted to 54.48 volts DC as measured at the system
sense points at 50% of full load and nominal input. “Percent of Full Load” refers
to percent of 55 Amperes.
