The 15 Amp Furman P-1800 AR delivers a stable 120 volts of AC power to protect audio equipment from problems caused by AC line voltage irregularities such as sags, brownouts, or overvoltages-all of which can damage sensitive electronic equipment. The P-1800 AR accepts input voltages over a wide AC voltage range and transforms it to a constant output of 120V, ±5V. Voltages beyond that range may also be converted to usable levels, depending on the range variance.

Additionally, the P-1800 AR is a full-featured power conditioner that filters and purifies AC power, reducing line noise and ensuring optimum performance. Not only will your equipment perform better with Furman's Linear Filtering Technology (LiFT), but it will also be fully protected by their exclusive Series Multi-Stage Protection (SMP) and Extreme Voltage Shutdown (EVS) technologies. This circuitry provides an extremely high level of power protection.

  • Furman's exclusive SMP technology provides high level of surge & spike protection
  • LiFT offers AC power filtering to ensure clean power for audio & video clarity
  • Advanced EVS circuitry detects dangerous voltage irregularities and safely powers down itself and connected equipment in unsafe conditions
  • LED status indicators warn you when voltage is outside of nominal range or when protection has been compromised
  • Isolated outlet banks minimize inter-component interference and noise contamination
  • Large digital voltmeter/ammeter with discrete dimmer button displays incoming line voltage
  • Three widely spaced outlets accommodate bulky AC power transformers
  • 15 Amp rating featuring a high inrush magnetic circuit breaker for added protection
  • Nine total outlets (8 rear panel outlets and one front panel convenience outlet)
  • True RMS Voltage Regulation delivers a stable 120 volts of AC power to protect equipment from problems caused by AC lne voltage irregularities
  • Rear panel BNC connector powers any standard gooseneck lamp for rear rack illumination
  • Maximum Current: 15 amps @ 124 Volts
    Line Cord: Captive 3/14 AWG, 10 ft. black cord with NEMA 15 plug

    Comments about Furman P-1800 AR Voltage Regulator / Power Conditioner:

    I am a professional guitar tech for a touring band that uses very old and very sensitive vintage amplifiers, keyboards, and guitars. During a summer tour of various ampetheaters, I found that the stage power in various arenas / amphitheaters/ festival stages (be it Red Rocks, The Forum, Lollapalooza, or any given amphitheater) was very inconsistent with noise, ground hum, electrical issues. I would often have to lift one amp, both amps, a keyboard, all depending on where my drop was at whatever venue. This unit has not only helped keep the power feeding the amps consistent every time, but now pedalboards and keyboard power are all running from the same supply and extended upstage. This is a VERY reliable well built unit. I love that it's a single rack space and has a digital voltage read on the front. Even a usb outlet! A solid investment in not only the tone of your amplifier but also life and longevity of your electronics. It's not the most glamorous purchase, but I consider it to be the glue that binds a very temperamental rig together night after night. I get a little more sleep at night knowing our power issues are under control in any setting. Buy one. Now.

    Furman = Mr. Clean power!

    Comments about Furman P-1800 AR Voltage Regulator / Power Conditioner:

    I run stereo amps and also use effects for my guitar setup. I was having some serious ground loop issues and dirty power that I needed to attenuate for recording. I looked into Furman's products and stumbled across the P-1800AR. I decided to wing it and see what it could do. When it arrived, I powered it up right away and was blown away by how quite and clean my rig had become! It also protects my investments from any crazy power problems that could occur. This is the real deal and the Furman warranty is excellent! My only compliant is I wish the P-1800 AR had more isolated power banks for guitar amps. Very cool piece of gear though!
