Ac Input Ratings - Vertiv NetSure R48-2000 User Manual

• Regulation:
a) Static: Steady state regulation is ±0.5% as controlled within the rectifier for any and all combinations
of load from no load to full load, input voltage, and input frequency at a constant ambient
temperature. The associated system controller may provide increased regulation.
b) Dynamic: For any step load change within the range of 10% to 90% of full load within 50
microseconds, per Telcordia GR-947-CORE, the maximum voltage transient will not exceed 5% of
the initial steady state voltage within 50±10 microseconds. Recovery to within 1% of the initial
steady state voltage does not exceed 4 milliseconds.
• Filtering:
a) Voice Band Noise: Complies with Telcordia GR-947-CORE.
1. R48-2000 (1R482000) and R48-2000H (1R482000H): Output noise according to Telcordia
GR-947-CORE is <32 dBrnC at normal input and full load.
2. R48-2000e (1R482000e): Output noise according to Telcordia GR-947-CORE is <38 dBrnC
typical at normal input and 20% to 70% of rated load.
3. R48-2000 (1R482000) and R48-2000H (1R482000H): Psophometric noise is ≤1 mV at 5% to
100% of rated load.
4. R48-2000e (1R482000e): Psophometric noise is ≤2 mV typical at 20% to 70% of rated load.
b) Wide Band Noise: Complies with Telcordia GR-947-CORE.
1. Wideband noise emission is <250 mV peak to peak between 0 Hz – 100 MHz, and <100 mV rms
in any 3 kHz band 10 – 20 MHz.

AC Input Ratings

• Voltage: Nominal 120/208/240 volts AC, single phase, 3-wire, 50/60 Hz, with an operating range of 100
to 250 volts. Acceptable input frequency range is 45 to 65 Hz.
Permitted Variation: 85 to 300 VAC.
• Harmonic Content (THD): ≤5% from 50% to 100% of rated load. Meets EN61000-3-2.
• Inrush Current: Peak does not exceed 1.5 times of the peak value of the maximum steady-state 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.
