Compatible 12V Adapter for Shure Wireless Systems

This 12V AC/DC adapter replaces the Shure PS21US supply for PGX4, SLX4, FP22 and FP33 mixer models. It accepts a worldwide 100-240VAC input at 50/60Hz for direct wall connection. The unit is built as a direct replacement for the original power supply cord. It suits users who need a new charger for these specific Shure wireless receivers.

Verify Connector and Voltage Before Ordering

Confirm that the Shure device requires a 12VDC input and matches the listed PS21US, PGX4, SLX4, FP22 or FP33 model numbers. The adapter provides a fixed 12V output with integrated safety protections including over-current, over-voltage and short-circuit safeguards. Ensure the barrel connector polarity and dimensions match the original equipment exactly. No other voltage or connector variations are supported by this unit.

Six-and-a-Half-Foot Cord and Certified Safety

A 6.5 Ft power cord allows flexible placement of the wireless receiver away from the wall outlet. The adapter carries FCC, CE and RoHS certifications confirming compliance with electromagnetic and hazardous-substance standards. Internal smart-chip circuitry adds overload, overheat and anti-interference protection during operation. These features replace the original supply without altering the receiver’s performance.
