This is a brand new, good quality replacement power supply which is 100% compatible with the Spectrum 16K, 48K, and 48K+ models).
It is a modern, efficient power supply rated at 1.5A.
The original Sinclair 16K & 48K PSU's were rated at 1.4A, so this more efficient, 1.5A replacement power supply has plenty of spare "head room" for additional modern day, or original power demanding spectrum peripherals.
Can also be used with the Spectrum 128 (toast rack) and Spectrum +2 (grey model), but if you are using other peripherals powered by the computer, our 2.5A model would be more suitable (see our other listing) - these Spectrum models originally shipped with a 2.1A power supply.
Can be used with our Sinclair ZX Spectrum in-line power switch (see our other listings).
Important:
This power supply is wired with the end plug "centre pin negative", so must not be used with any other device than the Spectrum models listed above.
It is not suitable for use with the Spectrum +2A, +2B or +3 models.
