This is a brand new, replacement switching power supply which is 100% compatible with the Spectrum 16K, 48K, 48K+, 128 and +2 (grey models.
A modern, efficient regulated power supply PSU rated at 2A (the original Sinclair 16K & 48K PSU's were rated at 1.4A) giving plenty of "head room" for additional peripherals.
This new power supply is a regulated, high efficiency unit which means that more power is actually available than supplied by the original unregulated 2.1A PSU's shipped with the spectrum 128 and +2 grey model. This makes it a perfect replacement for those models too.
Can be used with our Sinclair ZX Spectrum in-line power switch (see our other listing).
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.
