The most sophisticated of the Unilab Retro range, the Regulated Lockable Power Unit offers smooth, regulated d
c
at 2, 4, 6, 9 or 12 volts, at up to 4 amps
This unit is for quantitative circuit work, e.g.Ohm's law or where a constant voltage is required under variable load
The voltage is selected using a five‐position switch, and can be locked either at a particular voltage, or within a range of voltages, by way of hex socket screws surrounding the selector switch
An Allen key is provided for the teacher or technician to set the desired locks
The power is output from shrouded 4mm sockets, and the shroud can be partially unscrewed for other types of connection, such as bare wires
The unit has two in‐built layers of protection
The first is a thermal trip on the secondary circuit, with a reset button for when the problem load has been disconnected
The second is a 1A mains fuse, accessed from the front panel, on the primary circuit
Locking mechanism to limit or pre‐set the voltage available to students in specific experiments.4mm output socket/terminals
Thermal ”trip”, which can be reset shortly after removal of the excess load
Robustly made with captive mains lead and integral cable wraps on the back panel
Protected by a time delay mains fuse in the front panel
Complies to EN61010 2010, certificate available on request
