Palmer PWT 12 IEC

A Palmer Power Supply Designed for Modern Pedalboards

On a pedalboard, the power supply is often the number one source of unwanted noise, hum, and loss of definition, especially as pedals multiply. The Palmer PWT 12 IEC belongs to the brand's new generation of isolated power supplies: the goal is clear, to provide stable, clean, and usable current on stage as well as in the studio, even with demanding pedals. Thanks to its very low-noise isolated outputs, it targets guitarists and bassists who want a cleaner signal and a more reliable pedalboard on a daily basis.

Who Is It For and What Are Its Uses?

The PWT 12 IEC is aimed at musicians who use multiple effects pedals and want to avoid unwanted interactions between power supplies (noise, hiss, instabilities). It is particularly relevant if you play with overdrives, fuzz, modulations, and delays on the same board, or if you alternate between rehearsals, concerts, and recording sessions: an isolated and protected power supply saves time, peace of mind, and sonic consistency.

Its "IEC plug" format and universal power supply also make integration into a clean rig easier: you plug in, power up, and focus on playing rather than hunting down noise.

Isolated Outputs, Variable Voltages, and USB: A Power Supply Built for Flexibility

12 Isolated 9V Outputs: The Foundation of a Quiet Pedalboard

The strong point of the PWT 12 IEC is its 12 isolated 9V DC sockets, with center-negative polarity. Each output has its own regulation and isolated transformer: this architecture limits ground loops and reduces noise that appears when multiple pedals share the same power supply. The result: a cleaner sound and a more "pro" pedalboard, even in challenging electrical environments.

2 Variable Voltage Outputs 6 to 18 V: Headroom and Vintage Textures

The two variable voltage outputs (6 to 18 V) offer real flexibility. You can adjust the power supply according to a pedal's needs (or your taste), resulting in more headroom on some overdrives, or conversely, spongier and more compressed textures by lowering the voltage. It's a simple approach to evolving your tone without changing pedals.

USB-C + USB-A 18 W: Convenient for Accessories and Hybrid Setups

The PWT 12 IEC includes a USB-C and a USB-A output with 18 W. This is ideal for keeping a phone charged (setlists, metronome, recording) or powering compatible equipment, including some controllers or MIDI keyboards depending on their needs. A very practical detail when your pedalboard also becomes the center of your setup.

Output Protection and Included Accessories

Each socket benefits from short circuit and overload protection, securing the entire system: a faulty pedal or a problematic cable should not compromise your whole pedalboard. Finally, Palmer provides everything needed to start immediately, with DC cables and a power cable.
