	I can't find a Dec std 9 listing for AS255, but the surge current should be below 70A max. For VRC21: AC power group A Nominal voltage: 100-240 Volts, single phase Voltage range: 88-256 Nominal frequency: 50-60 Hz Frequency range: 47-63 Hz Number of AC phases: 1 Input current: Typical Maximum Phase A: 1.5 Amps 2.4 Amps Phase B: 0.0 Amps 0.0 Amps Phase C: 0.0 Amps 0.0 Amps Neutral: 0.0 Amps 0.0 Amps Ground: 0.0 milliAmps 0.0 milliAmps Power consumption: 90 Watts 150 Watts Standby power consumption: 30 Watts Apparent power (maximum): 0 Volt-Amperes Inrush current: 70.0 Amps Start-up current: 70.0 Amps Start-up duration: 1.0 seconds Power factor: 0.45 Crest factor: 0.00 AC power group B Nominal voltage: 100-240 Volts, single phase Voltage range: 88-256 Nominal frequency: 50-60 Hz Frequency range: 47-63 Hz Number of AC phases: 1 Input current: Typical Maximum Phase A: 1.0 Amps 1.3 Amps Phase B: 0.0 Amps 0.0 Amps Phase C: 0.0 Amps 0.0 Amps Neutral: 0.0 Amps 0.0 Amps Ground: 0.0 milliAmps 0.0 milliAmps Power consumption: 90 Watts 150 Watts Standby power consumption: 30 Watts Apparent power (maximum): 0 Volt-Amperes Inrush current: 60.0 Amps Start-up current: 45.0 Amps Start-up duration: 1.0 seconds Power factor: 0.50 Crest factor: 0.00
