Palmer PWT 05 MK2 professional pedalboard power supply with 5 individually ISOLATED outputs and IEC mains connection, in mint cosmetic condition and perfect working order.
Purchased new in November 2025, so it is still under warranty. The original purchase invoice will be provided to the buyer.
It has been very well looked after and works perfectly. I'm only selling because I've upgraded my pedalboard power supply.
The unit comes as a complete original set, including the original box, power and connection cables, Y-cables, daisy-chain cable, manual/documentation and all accessories originally supplied.
One of the main advantages of the PWT 05 MK2 is that its five 9V DC outputs are individually isolated.
Unlike basic daisy-chain power supplies, electrical isolation between the outputs helps eliminate ground loops and the associated hum and noise, making it particularly suitable for pedalboards combining analogue and digital effects.
Each isolated output provides a stable 9V DC / 250 mA, centre-negative.
Another particularly useful feature is the standard IEC mains input.
Rather than relying on an external wall-wart style power adapter, the PWT 05 MK2 connects directly to mains power using a standard IEC cable – a neat and practical solution for a permanently wired pedalboard and particularly convenient for rehearsals and live use.
The unit also features a mains On/Off switch and voltage selector.
The supplied Y-cables make the five isolated outputs particularly flexible:
5 × isolated 9V DC outputs, up to 250 mA each
500 mA @ 9V: two outputs can be combined using the supplied current-doubling Y-cable – useful for higher-current digital pedals
18V: two 9V outputs can be combined using the supplied voltage-doubling Y-cable for compatible 18V pedals
1-to-5 daisy-chain cable: allows multiple low-current pedals to share one output, provided their combined current draw remains within 250 mA
Typical analogue/digital pedalboard:
Use the five isolated outputs independently for a tuner, compressor, overdrive/distortion, modulation pedal and delay/reverb. Each receives its own isolated power supply, helping minimise unwanted noise and ground-loop hum.
Digital pedal + analogue pedals:
Combine two outputs to provide 9V / 500 mA for a more power-hungry digital pedal, while retaining three independent isolated outputs for your other pedals.
The included daisy-chain also gives you the option of powering several low-current pedals from one output when required.
