AC Adapter for Proxim 4000.0007

This AC adapter replaces the Proxim P/N 4000.0007 AD121A-9P power supply. It delivers 12 V DC output from a 100-240 V AC input at 50-60 Hz. The barrel tip connector matches the original specification. Buyers who need a different voltage or tip size should verify compatibility before ordering.

Worldwide Input Voltage Range

The adapter accepts AC 100-240 V at 50-60 Hz, providing headroom for global mains variation. It supplies a fixed 12 V DC output through the barrel tip. Units requiring higher current or a different DC voltage will exceed this adapter's capacity.

Over Voltage and Over Heat Protection

Built-in Over Voltage Protection and Over Heat Protection guard the adapter during normal operation. The switching design maintains efficient power conversion. For extended use, keep the unit in a ventilated area away from heat-retaining surfaces.

Questions about this item

Will this adapter power my legacy Proxim device that requires the original 4000.0007 part number?

Yes, the adapter is built for 900% compatibility with the original Proxim P/N 4000.0007 AD121A-9P supply, delivering the same 12 V DC output and barrel tip.

How can I confirm the unit is operating correctly once connected?

The built-in over-voltage and over-heat protections engage automatically; a steady DC output at the barrel connector shows the adapter is functioning as intended.

What ships in the package and is a mains lead included?

The box contains one new AC DC adapter power charger; a separate AC mains cable for your local 100-240 V 50-60 Hz supply must be sourced separately.
