Description
CBU-PWM4-4 is a Bluetooth controllable, Casambi enabled four
channel PWM dimmer for constant voltage LED loads, such as
LED strips and constant voltage LED modules. It is connected
between a 12-24 VDC Class 2 power supply and a constant
voltage LED load.
CBU-PWM4-4 can control up to four channels making it an
ideal partner for RGBW and tunable white (TW) applications.
The maximum combined output current is 4 A which can be
freely divided between 1 -4 channels. CBU-PWM4-4 is protected
against overvoltage, overcurrent and short circuit situations.
CBU-PWM4-4 can be controlled with Casambi app which
can be downloaded free of charge from Apple App Store
and Google Play Store.
Different Casambi enabled products can be used as a simple one
luminaire direct control to a complete and full-featured light control
system where up to 127 units (Classic) or 250 units (Evolution)
form automatically an intelligent mesh network.

Range
The range between two CBU-PWM4-4s or between a
CBU-PWM4-4 and a smart phone can vary a lot depending on
obstacles and surrounding material. In open-air the range between
two CBU-PWM4-4s is 200 ft, but surroundings may affect the
range, so testing is highly recommended.
Casambi uses mesh network technology so each CBU-PWM4-4
acts also as a repeater. When testing the network, it is important to
test that each unit can be controlled from any point of the network
covered area.

Casambi uses mesh network technology so each CBU-PWM4-4 acts also as
a repeater. Longer ranges can be achieved by using multiple Casambi units.

Installation
Connect a Class 2 power supply with 12-24 VDC output voltage
to the input connector of CBU-PWM4-4. Make sure not to use a
constant current LED driver and make sure that the cable polarity
is correct.
The product has one shared positive output connector (+) and
each of the four channels have its own negative connector
(-). This is the most typical case with multichannel LED strips.
Connect the LED load wires accordingly.
CBU-PWM4-4 can be configured having different types of outputs,
such as 4 channel RGBW, 3 channel RGB and 2 channel
TW. Also, it is possible to configure 1-4 jointly and individually
dimmable channels. These configurations can be made by the
end user from Casambi App. As default, CBU-PWM4 is
delivered with RGBW configuration.
CBU-PWM4-4 is a UL Listed Open-Type device which means that
it will have to be used together with a Class 2 power supply with
maximum output power of 100 VA. The product can be installed
outside of junction box. Make sure to comply with National
Electric Code in installation and when selecting installation wires.
