Introduction
The JANDS HUB24 is a unique combination of dimmer channels, power distribution
and isolated DMX splitting, all in one compact and low noise package. The HUB24 is
specifically designed for demanding touring and theatre applications and is ideal for
shows where a mixture of conventional and automated lights are used.
Especially suitable for live shows, school auditoriums, trade shows and other similar
applications, the HUB24 eliminates the usual clutter associated with dimmer racks,
power distribution boxes and DMX splitters. The HUB24 also includes the ability to
record and playback snapshots and chases without a lighting console.
One HUB24 incorporates:
– 15 Dimmer outputs
– 9 Power Distribution outputs
– 1 in 2 out opto-isolated DMX splitter
HUB24 dimmers use a chokeless IGBT output topology for reduced weight and low
acoustic noise. The unit is primarily cooled by natural convection; small fans will turn
on only in extreme circumstances.
The unit monitors the supply current drawn on each phase. If more than a preset limit is
drawn from a phase, all the dimmer outputs on that phase are dimmed down until the
current is near to the limit. This ensures connector and upstream circuit breaker current
ratings are not exceeded for long periods of time.
The HUB24 features microprocessor-based digital control. A menu-driven user
interface, consisting of only two buttons, an encoder wheel and a large graphics LCD,
enables the user to easily monitor and select all the built-in functions.
The user has the ability to soft patch the channels out of sequence, test selected channels
while the remainder of the dimmer stays on-line, download custom dimming curves,
capture or build up to eight non-volatile snapshots and chases.
Other functions provided are dimmer “soft” start, bad (soft) neutral detection,
monitoring supply voltage, current and other working parameters of the unit.
Control signal connection to the HUB24 is via a standard DMX-512 socket located on
the front panel along with DMX through and two opto-isolated DMX outputs. Also
located on the front panel are the dimmer and distribution output sockets. The three
phase power entry and a cable tray are located on the rear panel.
The unit will “wake-up” in the mode it was last programmed to run - an ideal function
for stand alone applications. If no particular mode has been previously defined, the unit
looks for DMX control. The user has the ability to set how the HUB24 will respond if
DMX control is lost, but in all cases the dimmer outputs will turn off if the DMX signal
is not restored within 10 minutes.
The HUB24 range of dimmers have been designed to receive future optional software
upgrades to the operating system, without opening the unit.
The HUB24 is convenient to transport due to its solid carry handles, protective
transportation bag and built-in cable tray for storage of the three phase cable.
An optional wall bracket allows the HUB24 to be wall-mounted and optional hand-rail
mounting brackets allow the HUB24 to be mounted on a catwalk rail.
