Act 2
(1983)
Portable Lighting Control
Compact, rugged and
easy to use, Act 2 is the economical way to control up to four 650W lighting
loads from a mains supply of 13 Amps. The two dimmers are mastered by
independent faders, and each of the four output sockets can be switched
off, full on, or under control of a dimmer.
Act 2 is supplied
with 5 metres of mains cable and four output plugs, and the optional mounting
plate converts the unit into a wall or stand mounted dimmer.
Developed at the
request of agents for a basic two channel lighting control. Introduced
Autumn 1983.

Act 6
(1984) Economy priced portable dimmers
1984 - 5A, 15A, Schuko versions
The chassis design of Act 6 will permit a wide range of socket types to
be used for individual market areas. All types incorporate specially chosen
panel fuses which will survive the usual form of abuse that this type
of dimmer inevitably suffers - namely the removal and replacement of fuses
on load - and LED indication of fuse continuity and the status of the
power supply.
All the dimmer electronics are mounted on a single pcb which includes
the power intake terminals, and connections to the triacs, mounted on
the extruded aluminium heatsink case, and the connection to the control
panel pcb. Each dimmer circuit is rated at a full 10 Amps, and the total
continuous load is 45 Amps. If the pack is overloaded for any appreciable
time, an internal thermal safety trip will switch off power, and will
reset when the temperature reduces to within its normal operating range.
The circuit design
of Act 6 incorporates a low voltage power supply to supply a Tempus desk
which will plug directly into the local control panel of Act 6 when a
full manual remote control is required.
As mentioned above,
Act 6 is not intended to replace Tempus as it performs to a different
specification.
