Introduction

These three “retro” power supplies are intended for general laboratory use and have some

features in common with the original UNILAB power supplies:

 All have a locking mechanism, that can limit or preset the voltage available to

students in specific experiments.

 All have 4mm output socket/terminals, for connection of bare wires as necessary

 All have a thermal “trip”, which can be reset shortly after removal of the excess

load.

 All are robustly made, with captive mains lead and integral cable wraps on the back

panel.

 All are protected by a time delay mains fuse in the front panel.
