BOSS PSA-230S AC / DC power supply (PSU) 9v 500mA.
The new upgraded BOSS PSA-230S delivers 9v DC at up to 500mA (previous version PSA-240 was only 200mA). The upgrade to 500mA allows more than one Boss effects pedal to be connected and operated at the same time by using power supply link cables. You can also use the PSA-230S with just one single 200mA pedal and then the power supply delivers only 200mA as required by the pedal.
The BOSS PSA-230S AC/DC regulated power supply converter (PSU) converts UK mains voltage to DC 9v for most BOSS guitar and bass guitar effects pedals, stomp boxes and for some other Roland and BOSS products. The BOSS PSA230 power supply is a switch-mode DC regulated and smoothed for BOSS guitar effects pedals and other 9v equipment.
The voltage and current are constant which means no hum, which is essential for guitar effects pedals, especially distortion pedals. Humbucker guitar pick-ups reduce hum, hence the name, while single coil pick-ups are more prone to hum. To reduce hum, when using distortion pedals, switch to the humbucker pick-up if your guitar has one, or switch to two single coil pick-ups combined if your guitar has single coils. An example of a humbucker guitar is the Gibson Les Paul and a single coil guitar is the Fender Stratocaster.
Most BOSS guitar effects pedals only require a small current so several pedals can be connected to one single BOSS PSA-230S power supply unit (PSU) using a power supply splitter cable.
The BOSS PSA-230 regulated AC/DC power supply (PSU) specifications:
- Input voltage: 220-240v AC 50hz (This is the standard UK voltage)
- Output voltage: 9v DC 500mA regulated (old version 200mA)
- Output connector polarity: centre female socket negative (-) and outside positive (+)
The BOSS PSA-230 ES power adaptor has a built in output current protection circuit. Use of the adaptor with a device or devices with a current draw greater than 500mA will trigger the protection circuit. Power is cut off or intermittently supplied while the protection circuit is activated. Most guitar effects pedals draw less than 300mA so they will not trigger the circuit. To de-activate the current overload protection follow these steps:
- Turn off the power to the connected pedals or device
- Check that the total current consumed by the device is no more than 500mA
- If the device draws 500mA or less, then re-connect and turn the power back on
