The AR-1230 is designed to provide a steady, stable 120 VAC output. It accepts input voltages from 97V to 141V and transforms them to a constant 120V, ±5V. Voltages beyond that range may also be converted to usable levels, depending on how far out of range they are. The AR-1230 can handle loads totaling up to 30 amps as long as the input voltage is above 124 volts. For voltages below that level, its capacity must be derated at approximately .15 ampere per volt.

Features:

• Delivers a stable 120 ±5 VAC whenever the input AC line voltage is between 97V and 141V
  
• Output capacity 30 amps
  
• One regulated, conditioned 30A twistlock outlet and six 15A outlets on the rear, plus two 15A outlets on the front
  
• Eight-tap toroidal autoformer
  
• 10-LED bargraph Input Voltage meter
  
• 10-LED bargraph Output Current meter
  
• Extreme overvoltage/undervoltage causes instant shutdown, protecting equipment
  
• Extreme Voltage Shutdown indicator LED
  
• Output In Regulation indicator
  
• Low stray magnetic field leakage
  
• Rear panel fan provides cooling for continuous operation
