BASEUS 9V AC adapter 1A 6 ft center-negative

SKU CH-JM8D-3ZG14

9V AC/DC adapter delivers 1 A output with centre-negative plug and 6 ft cable for Boss PSA-series pedals

  • TypeAC Adapters
  • Powers a wide range of Boss pedals with a single adapter
  • Delivers stable 9V 1A output for consistent performance
  • Built-in OVP OCP SCP protection safeguards connected gear
  • Six-foot cable gives flexible stage or studio placement
  • V-0 grade flame-retardant materials enhance safety during use

Purpose and fit

This 9V AC adapter delivers 1 A of centre-negative power for Boss PSA-series pedals. It replaces the PSA-120S and matches the full PSA-100 through PSA-240S lineup. The six-foot cable reaches pedalboards without strain. Musicians needing a direct replacement for the original supply will find the voltage and polarity identical.

Build integration

The unit accepts 100-240 V input at 50-60 Hz, so it works on global mains without a separate transformer. OVP, OCP and SCP protections guard connected pedals against voltage spikes, over-current and short circuits. A V-0 flame-retardant casing meets basic safety requirements. The fixed 6 ft cord removes the need for an extension lead on most boards.

Who should buy

Guitarists and keyboardists who own any listed Boss compact, multi-effects or loop-station pedal and need a new factory-spec power source. Players with pedals requiring centre-positive polarity, higher current than 1 A, or a different voltage should look elsewhere. Buyers needing isolated multi-output supplies for daisy-chain-free boards will not be served by this single-output design.

Highlights

  • Delivers stable 9V 1A output for consistent performance
  • Built-in OVP OCP SCP protection safeguards connected gear

Questions about this item

What is the output limit that appears first during continuous use?

The adapter is rated at 9 V and 1 A, so the 1 A current ceiling is the first limit reached under sustained load.

How much heat or noise does the unit produce when running all day?

The supply has no fan; it relies on passive cooling and V-0 grade flame-retardant housing, so it runs silently and stays warm but within safe limits.

Which pedals or devices must I already own for this adapter to work?

It fits Boss pedals that use a centre-negative 9 V DC jack, including the DS-1, RC-1, RC-3, TU-2, TU-3, SD-1, RV-5, RV-6, DD-3, DD-7, DD-20, ME-50, ME-80, GT-10, HM-2 and GT-1B.
