3. Functions . CRD400 INS
3.1 Performance characteristics
The device can be controlled via the Casambi app, available for iOS and Android. Another optional operation ist given by the push
button input.
Casambi app automatically identifies the device and can be integrated into existing networks. All functions triggered by the buttons are
individually configurable.
As soon as the device is added to your network, it can be operated. Groups can be formed, scenes and timers can be created.
You can find all Casambi app related help on the official Casambi support sites at: .https://support.casambi.com
Product description
Digital leading- / trailing edge phase cutting dimmer with automatic load detection for a single dimmed phase. Equipped with an
additional push button input which extends the dimmer with a fast analogue control. Local control is so much easier.

3.2 Sicherheitsfunktionen
Derating
The maximum dimmer load is possible up to an ambient temperature of 50 ° C. Between 50 and 70 ° C
(ta) (ta max allowed = t critical = ) tc
the maximum power decreases to 0 Watt.
The specified max. power rating applies to installation in a sufficiently ventilated location. In case of lower heat dissipation, e.g. in
cavity walls, flush-mounted/ junction boxes, as well as in case of mutual heating of several devices, the max. power rating is reduced
accordingly.
In case of overtemperature automaticly derating takes place, which means the power will reduced depending on the temperature.
Status-LED is indicating over temperature and the brightness of the lamps decreases.
Fig.: Derating curve of the CRD400 INS
Temperatures higher than 50°C are not specified in the approved ambient temperature.
However, the dimmer does not switch off hard and continues to adjust downwards even at higher temperatures.

5. Installation . CRD400 INS
5.1 Considerations and planning
A Casambi network is a mesh network and every participant (dimmer, switches, etc.) extend the reach of the network.
Casambi is based on the energy-saving Bluetooth 4.0 standard. If a module is nearby, all luminaires within range of this module can be
controlled.
Bluetooth has a range of up to 20 m. Plan your network in such a way that the radio coverage of the modules is guaranteed with each
other and no dead spots arise.
If there are gaps in the network or modules are positioned at the limit of the radio coverage, strange errors can sometimes occur.
Before putting the device into operation, make sure that the correct power supply and power class is selected.
Dimmer for brightness control of illuminants such as incandescent lamps, high-voltage halogen lamps, dimmable LED lamps for 230 V.

Power calculation depending of the used lighting source
Load type cutting method Percentual rated output power
Ohmic trailing edge  100 %
LED trailing edge approx. 80 %
copper transformer leading edge*approx. 20 %
* leading edge is (only) for copper transformersmandatory
Example:
A rule of thumb calculation for LEDs with internal power supply:
-Given is trailing edge as cutting method
- 20x LED 7.5 watts = 150 watts (nominal power of the LEDs)
- plus additional charge 20% (for capacitive parts of the LED load characteristic)
Result: 180 watts as total power is required.
