What this adapter powers

The SSC-090050 is an original AC adapter built for Plantronics headset systems W740, W430, W8210 and W8220. It replaces a lost or damaged charger so the headset base receives the correct 9 V supply. The unit is supplied new and matches the manufacturer part number 203158-01.

Thermals noise and power draw

The adapter accepts a universal 100-240 V input at 0.2 A across 50-60 Hz mains. It delivers a steady 9 V output at 0.5 A (500 mA) with built-in protection against incorrect voltage, short circuit and internal overheating. No fan is present, so operation is silent.

The specification that decides fit

Output is fixed at 9 V and 0.5 A; the plug polarity and dimensions are those specified by Plantronics for the listed headset systems. If your headset requires a different voltage, current or connector, this adapter will not work.

Questions about this item

How do I connect the SSC-090050 adapter to my W740 headset without damaging the port?

Plug the barrel connector straight into the headset charging socket; forcing it at an angle bends the centre pin and breaks the connection.

What part of the SSC-090050 will wear out first and need replacement?

The output cable near the barrel plug frays from repeated bending; replace the whole adapter when the insulation cracks.

At what load does the SSC-090050 hit its thermal limit during continuous charging?

The adapter is rated for 9V at 0.5A; sustained operation at that output triggers the internal over-temperature protection first.
