Features
Isolation
•
Individual outlet protection
All ten outputs feature individual isolation and protection. This means that
if a fault occurs on a piece of equipment connected to one output, fixtures
on the other outputs are totally protected. In addition the input
connectors have their own protection, this gives a double barrier between
fixtures and the console and protects the console against a fault on the
mains supply to the buffer itself (i.e. if the buffer unit was inadvertently
connected across two phases).
•
1000 Volts optical isolation barrier
Each outlet has an optical isolator that is capable of withstanding voltages
of up to 1000V. Each isolator has its own power supply eliminating any
direct electrical connection between outputs.
Self-healing technology makes sure that the outlets can resist up to 530V
over its data pairs. This means that after such a fault the outlet works fine
again with normal DMX signals.
•
Short circuit protection
Each outlet is protected against short circuits, or incorrectly wired
connectors.
•
Modular isolation
All the components that provide the opto-isolation are built into a single
plug-in module for each channel making servicing ultra-simple. In addition
each module is completely interchangeable with other channels including
the input module.
•
Line voltage protection
Not only does the Hub protect your various pieces of equipment from
inadvertent DMX-to-mains connection it also protects itself. Each
individual output is protected so that no damage will occur to the buffer
even if they are connected directly to 230V by mistake.
Even a built-in rechargeable battery backups the complete isolation
functionality when a mains failure occurs (see “Power fail management”).
