Can I use the DIMMAT LEDs to dim?
The dimability of LED lighting products depends among other things on the lamp ballast used. The lamp must always be dimmable according to the manufacturer, i.e. operating instructions or information from the manufacturer! Even if the LED lamp is dimmable, one must take into account that each 2-wire dimmer requires a base load to function securely, i.e. flicker free. With a “normal” phase control dimmer (Triac dimmer), dimmable LED-bulbs can usually be dimmed.
The base load specified for these dimmers can usually be reduced by a factor of 2-4, i.e. for a 40W base load, LED lamps from approx. 10W are also dimmable. This is not the case for phase angle control dimmers that require an operating voltage, such as the DIMMAT, in order to function, which has to react to the sensor surface being activated. For these dimmers, such “standby” power consumption can lead to the connected LED lamps flickering, which in turn depends on the structure of the ballast unit. There are ballasts that have so-called bleeder resistors built-in for this “purpose”, which is essentially supposed to ignore this “standby” power; however this is not always clear from the manufacturer.
Therefore the current recommendation is that (even dimmable) LED lamps should not be operated using the DIMMAT. Since the nature of the ballast of the LED-bulbs is not known to us, an eventual malfunction or possible defect cannot be excluded. The current limited by the fuse of a standard 400W dimmer can in any case be sufficient to destroy the LED lamp. In this respect, it must be stressed once again that the instructions of the LED lamp manufacturer must be strictly observed.
Can energy-saving lamps an 230V LEDs be dimmed?
In principle, only dimmable ESL and 230V – LEDs can bedimmed, i.e. it must be explicitly stated on the light sources. In most cases, you will find information on the lamp packaging about which dim procedures (phase angle control and/or trailing-edge phase dimmer) can be used to dim the lamp.
In view of the large number of different integrated ballasts, the lamps are usually made to be compatible with the commercially available dimmers by the lamp manufacturer. With the Kopp phase angle control dimmer (R and RL)[except dimmat] most dimmable ESL and 230V LEDs can be dimmed.
Which fine wires fuse is used in dimmat and dimmer?
For our phase control dimmer (dimmer/dimmat for conventional transformers), you need a time-lag 1.6A fine wire fuse. Our phase control dimmers (dimmers for electronic transformers) are equipped with an electronic fuse, which does not have to be replaced.
I would like to dim serveral lamps at a total of more than 500 Watt. Is this possible?
This is quite easy. Use two radio receivers with dimming functions to do so. Just be sure to note whether you have an electronic or a conventional ballast. Then programme your radio wall switch to both radio receivers.
For each dim operation, both radio receivers are controlled simultaneously by the radio wall switch and the lamps are dimmed at the same time. Furthermore: You can also programme multiple radio wall switches to the two radio dimmers. Then make it into a radio dimmer toggle switch
Why might the conventional transformer hum when dimming?
The steel core of the transformer consists of individual metal layers that may contain air inclusions. When dimming, a slight hum can be generated. If you therefore recommend an electronic transformer, pay attention to the VA power of the phase dimmer.
Which dimmer can be used for a fan?
A dimmer is generally not suitable for this application. This requires a special speed controller that we do not carry in our range.
What do "conventional transformer" and "electronic transformer" mean?
A conventional transformer has a steel core wrapped in copper and is therefore larger and heavier than an electronic transformer. An electronic transformer is smaller and lighter. A conventional transformer is required when dimming a phase control dimmer, an electronic transformer is required for a trailing-edge phase dimmer.
Is it possible to toggle switch with the dimmat
Yes, the dimmat combined with a button results in a toggle switch, which can even be dimmed using the button.
My dimmat is not working, even though it is connected correctly?
In order to protect the device itself, we have a time-lag 1.6A fuse (part number 3264 00087) upstream. Pull the fuse holder up and replace the fuse in place there
Why might the conventional dimmer hum when dimming?
This is due to physical reasons. The coil in the device may be producing an audible vibration when dimming.
Can energy-saving lamps, LEDs and fluorescent lamps be dimmed?
The dimmable energy saving lamps (e.g. Osram Dulux El Dim, Megaman) can be dimmed using our UP-dimmers for conventional transformers. Please note the information from the manufacturer of the energy-saving lamps. Non-dimmable energy saving lamps cannot be dimmed. Light-emitting diodes and fluorescent lamps currently cannot be dimmed either.
Is there also a dimmat as a trailing-edge phase dimmer?
No, the dimmat is suitable for incandescent and 230V halogen as well as low-voltage halogen lamps with conventional transformers 40-400VA
