A Palmer Powerbar Designed to Streamline Studio Power Management
Connecting effects units and organizing a patch bay opens the door to new sonic textures, but power supply can quickly become the weak point of a setup: scattered power strips, disparate adapters, tangled cables. The Palmer WT PB 40 RK addresses this need for order and reliability with a compact, universal solution designed to fit neatly into a 19-inch rack.
Its purpose is simple: to centralize the power supply for effects equipment in a rack format, keeping a clearer workspace and making daily maintenance easier.
Who Is It For and What Are Its Uses?
The WT PB 40 RK is aimed at musicians, home studio users, and studios employing multiple pedals or effects processors, as well as technicians who want a "ready-to-play" rack. It is especially useful if you want to stabilize the power supply of an effects chain, avoid multiple power adapters, and improve the ergonomics of a rack dedicated to processing (reverb, delay, modulation, multi-effects, etc.).
In recording environments, a better-organized power supply also helps reduce connection errors and maintain consistent cabling, especially when your setup changes frequently.
Output Isolation, Voltage Flexibility, and Built-in Protections
8 Isolated Outputs for Cleaner Power
This power supply offers eight separately isolated center-negative outputs. Isolating each output is an advantage when multiple devices share the same power source: it helps reduce unwanted noise and prevents certain artifacts (notably from digital circuits) from spreading throughout the rest of the setup.
Two Switchable 9V / 12V / 18V Outputs
To accommodate pedals or effects with different requirements, two outputs can be switched between 9V, 12V, or 18V. This flexibility is ideal if you alternate between several devices or integrate effects that require higher voltage reserves without needing to change external power supplies.
2,000 mA Total, LED Indicators, and Safety Features
With a total current of 2,000 mA, the Palmer WT PB 40 RK is designed to power multiple devices within the same rack. Safety is not overlooked: output protection against short circuits and overloads contributes to more reliable operation, while the built-in power and operation LEDs allow you to check the unit's status at a glance.

Questions frequently asked
Can the Palmer WT PB 40 RK power eight pedals or effects separately?
Eight centre-negative outputs are individually isolated. This isolation helps reduce the propagation of unwanted noise between connected devices.
What voltages are available on the switchable outputs?
Two outputs can be set to 9 V, 12 V, or 18 V. This configuration allows powering effects that require one of these three voltages.
What total current does this rack power supply provide?
The total capacity reaches 2,000 mA, or 2 A. This reserve is intended to power multiple effects devices in the same rack. The combined current draw of connected equipment must stay within this limit.
Is this power supply designed to be installed in a 19-inch rack?
The WT PB 40 RK is designed for clean integration into a 19-inch rack, especially to centralize power for an effects rack.
What protections and indicators are included?
The outputs have short-circuit and overload protection. Power and operation LEDs allow monitoring the unit’s status.
