Technical Features
::
Digital Dimmer Unit 12 channel DMX 512/1990 standard
with possibility of manual control of the 12 channels.
::
3 phases operation 380 Vac 50 Hz + NEUTRAL
Single phase operation 230 Vac 50 Hz
::
Dip-switch for digital address. (1/512).
::
Digital lamps pre-heat control adjustable
from 0% to 10% of the power
::
LC interference filters for don't generate any Audio noise
::
DMX-512 with 5 pin XLR male and female input/output.
::
Protection against short-circuiting:
Should a short-circuit occur, the DDP 1212 immediately
switches off the channel in question and then attempts
to switch it on slowly. If the short-circuit persists for three
times, DDP 1212 switches the channel off definitely.
::
Overload protection: The output is electronically limited
to a maximum of 12 A per channel,
no matter what load is applied
::
Protection against incorrect connections:
Through a fuse which blows to avoid overloading
damaging the unit's internal circuity.
::
Over-Heating protection: The maximum temperature
allowed is 90ºC and is measured on the cooling fin.
If this temperature is exceeded, the output is disabled
until temperature return in the limits
::
Forced ventilation: Use of the unit's fans does not in any
way compromise the possibility of using the dimmer
in locations in which noise has to be kept to a minimum
(theaters), DDP 1212 uses very low-noise fans which are
silent even when operating; their rotation speed is also
electronically controlled and directly proportional to the
dimmer's internal temperature.
::
power supply: Thanks to his detail planning, the power
supply of the logical part of the DDP 1212 is taken from all
the three phases. Without presence of one of the three
phases the channels powered with the others two phases
will work correctly too.
