SKU CH-ZJR6-2J9HJ

A 10 ft replacement power supply delivering 9 V at 3 A with FCC, CE and RoHS certification and multiple safety protections

  • 10 ft cable reaches distant outlets
  • 9 V 3 A output powers BOSS Roland PSB-120 units

  • Over-current, over-voltage, short-circuit protection guards gear
  • FCC, CE, RoHS certified for safety compliance

Extra-long 10ft replacement adapter

This WAWEIS AC adapter replaces the BOSS Roland PSB-120 power supply with a 10ft cord for extended reach. It delivers 9V at 3A output and accepts 100-240VAC input at 50/60Hz for worldwide use. The unit is new and built with safety certifications including FCC, CE and RoHS. Musicians and keyboard players needing reliable power away from wall outlets will find it suitable.

Upgrade from short or damaged cords

The 10ft length replaces shorter factory cables that limit placement of keyboards or pedalboards on stage or in studios. Built-in over-current, over-voltage, short-circuit and total-power protection guards connected gear against mains irregularities. The jump is worth it when the original adapter is lost, frayed or too short for your setup. Buyers who need a different voltage or connector type cannot use this model.

Simple plug-and-play installation

Connect the adapter to mains power and the output plug to the device; no drivers or configuration are required. The smart chip provides overload, over-charge, over-discharge and overheating protection during operation. Anti-interference isolation materials reduce noise in audio applications. Ensure the 9V 3A specification matches the device label before connecting to avoid damage.
