DMR.732 & DMR.733 it is a single channel trailing edge
dimmer. The dimmer’s output is capable of supplying up
to 350VA of load max. DMR.732 & DMR.733 can be used
for different type of loads such LED, Incandescent and
Halogen 230VAC dimmable lamps. DMR.732 offers high
flexibility in terms of communication and can be
controlled through 1/10V, and Push button while
DMR.733 supports Bluetooth protocol and Push button.
Furthermore,
DMR.732
supports
“aller
retour”
configuration between 1/10V and Push button. Both
dimmers offer overtemperature protection and have been
designed for interior use only. Finally, DMR.732 &
DMR.733 can be power supplied directly with 230VAC
and with their polymer case they can be easily fastened
to DIN (EN 60715) RAIL.
General notes and precautions.
Please make sure that during the installation, DMR.732
& DMR.733 should not be supplied with 230VAC.
Designed only for indoor use.
Do not try to fix any damage or malfunction, by opening
the DMR.732 or DMR.733. There is a risk for an
electrical shock hazard and the materials and parts
used in the DMR.732 & DMR.733 cannot be replaced.
This must be done by an experienced and specialized
technician of your supplier.
When DMR.733 is installed inside metallic
distribution boards, its range might be reduced.
Disconnect the power supply for any service.
Caution: Make sure that the total current of the loads
that are going to be connected to the dimmer is not
higher than the output current capacity of the dimmer.
The current of the load can be higher if their power
factor is smaller than one. Please refer to the technical
specifications of the loads to learn more about the
current they consume.
Compatible loads.
Dimmer DMR.732 & DMR.733 are operating with Trailing
edge mode and therefore the loads should also operate with
the same way of regulation. If your loads don’t indicate the
dimming mode, contact your supplier to inform you on this.
The types of loads you can connect are the following:
Dimmable Lamps and luminaires with LED
and operating voltage at 230VAC.
Dimmable Fluorescent lamps CFL (Compact
Fluorescent Lamps), with operating voltage
at 230VAC.
1
Dimmable Electronic transformers for low
voltage lamps.
Incandescent and Halogen lamps at
230VAC.
1.
For CFL lamps start up, you may need to adjust the output
to full for 2-3 seconds.
Connecting power sypply and load.
DMR.732 & DMR.733 must be switched off at the mains
before connecting / replacing any type of lamp or load in
general.
It is important that the total amount of the load does not
exceed the dimmer’s rated output power.
Only 230VAC dimmable loads should be connected to
the dimmer’s output.
The dimmers have to be always supplied through a
Miniature Circuit Breaker (MCB) as the figure indicates.
Use always MCBs with the appropriate current capacity
according to the load.
Avoid to use MCBs with current capacity over 10A.
Connecting & controlling the output with
1/10V (DMR.732).
The 1/10V input can be adjusted by connecting at the screw
terminals (marked with a variable resistor
) either a 100K
log potentiometer or a sink current 1/10V controller. Note
that the sink current 1/10V controller has polarity thus, the
positive end from this device must be connected to the
dimmer’s positive 1/10V input (marked with “+”) and the
negative end to the dimmer’s negative 1/10V input (marked
with “-”). By turning the controller “clock wise” the dimmer’s
output level can be adjusted from 0% to 100%.
Caution: Connecting the controller in the opposite way
may damage the controller or the dimmer or even both.
