The Canvas Power HP Plus is a perfect power solution for hybrid rigs running pedals, modelers, and/or multi-effect pedals allowing you to power the thirstiest of pedals with two, 3A (three Amp, or 3,000mA) outputs.

The HP Plus also has 7 isolated power outputs delivering up to 500mA of clean power at 9V and a 9/12/18V variable output. The 3A outputs can switch between 9V and 12V to power high-voltage pedals.

Canvas Power HP Plus brings simplicity and modularity to powering your modeler, multi-effect unit, or high-powered pedals. Boasting two ports delivering up to 3A each, and up to 500mA in seven ports of silent, isolated, and clean 9V power, the HP Plus is perfect for hybrid rigs using pedals and modelers like the Quad Cortex, HX Series, and many more. The Canvas Power series is built using modern switch mode supply architectures. This means each output is isolated, highly efficient, and heavily filtered ensuring they supply plenty of power with incredibly low noise.

The Power HP Plus is available for purchase as a standalone power supply or as a linkable unit to another supply via a 24V power link, allowing Canvas Power to grow with your power needs without adding another cable you need to plug into the wall.

The super slim 3 cm design allows Canvas Power Supplies to fit under nearly any pedalboard, and the included universal mounting brackets mean you don’t have to worry about your power supply staying put when you’re hustling to your next gig.

The onboard LED power meter lets you clearly see how much power is being consumed, and each output has its own LED indicator letting you know when it’s sending power.

Walrus Audio has developed custom 2.1mm barrel cables featuring a 90-degree plug on one end and a new ultra-short straight plug on the other, providing maximum flexibility for fitting the power supply into tight spaces. Of course, standard 2.1mm barrel cables are also compatible—but they’re not nearly as cool.

Features:  

  • Clean, multi-filtered, isolated power supply
  • Two 3A (3,000mA) outputs with selectable 9V or 12V
  • Powers most high-powered modelers and multi-effect units
  • Seven isolated 9V DC outputs delivering up to 500mA each
  • One variable output: 9V / 12V / 18V
  • One USB-C output
  • Modern switch-mode architecture for clean, quiet power
  • Optional linkable configuration via 24V power link
  • Expandable system via 24V link socket using any Canvas Power Link model
  • Slim 3cm design fits under most pedalboards, including Pedaltrain Nano and Metro series
  • Custom low-profile barrel cables included for 500mA ports
  • Includes various 2.1mm and 2.5mm reverse and standard polarity cables to support most modelers and multi-effect units
  • LED output indicators and onboard power meter
  • Mounting brackets included — no drilling required
