PRODUCT DESCRIPTION

• CBU-PWM4-4-LR 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 power supply and the constant voltage LED load.
• CBU-PWM4-4-LR 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 all output channels. CBU-PWM4-4-LR is protected against overvoltage, overcurrent and short-circuit situations.
• CBU-PWM4-4-LR can be controlled with the Casambi App, available for iOS and Android devices, as well as with traditional wall switches. The Casambi App can be downloaded free of charge from the Apple App Store and Google Play Store.
• Different Casambi-enabled products can be used from a simple one-luminaire direct control setup to a complete and full-featured lighting control system, in which up to 250 units automatically form an intelligent mesh network.

RANGE

The range between two CBU-PWM4-4-LR units or between a CBU-PWM4-4-LR and a smartphone can vary a lot depending on the design of a product in which the antennas are housed and on the environment in which they operate. Long-range capabilities can reach approximately 650 feet (200 meters) with a good line of sight connection between nodes. However, if the unit is encapsulated in a metal structure, the range can be only a few feet. Therefore, thorough testing is highly recommended.

Casambi uses mesh network technology, which means that each CBU-PWM4-4-LR also acts as a repeater. When testing the network, it is important to test that each unit can be controlled from any point in the network-covered area.

*The wireless range of a Casambi unit is dependent on several factors; how it has been integrated into a luminaire, where it has been installed; taking into consideration surrounding obstacles such as walls and other building materials that may block signals.

COMPATIBLE DEVICES

Compatible devices

• Android and iOS Operating Systems.

We support the latest OS versions for Android and iOS, and their last two major versions respectively.

CASAMBI MESH NETWORK COMPATIBILITY

There are different radio modes that can be selected when creating a network in the Casambi App: ‘Balanced’, ‘Better Performance’ and now ‘Long Range’ options. The CBU-PWM4-4-LR enables long-range capabilities only when the long-range radio mode has been selected and all the other devices within the network are long-range capable. It will revert to the shorter, standard range when deployed in networks set to ‘Balanced’ or ‘Better Performance’ modes.

INSTALLATION

• Make sure that the power supply voltage is switched off before making any connections.
• Connect a constant voltage 12-24 VDC Class 2 power supply to the input connector. Make sure not to use a constant current LED driver and make sure that the cable polarity is correct.
• The product features one shared positive output connector (+), with each of the four channels having its own negative connector (-). This configuration is standard for multichannel LED strips. Connect the LED load wires accordingly.
• Use 14-22 AWG solid or stranded conductor electrical wires. Strip the wire 1/4” from the end. Open the screw connector on top of the dimmer case and insert the wires into the corresponding terminals, tighten the screws. Overtightening the screws may damage the device. Make sure to connect the input and output correctly. If you install the dimmer in a heat-sensitive environment (e.g. inside a luminaire or in a ceiling outlet box above a luminaire), make sure that the ambient temperature does not exceed the specified maximum value. Using the dimmer in a heat-sensitive environment may limit the maximum output power.
• The proper operation of CBU-PWM4-LR requires a carefully calculated total power consumption, the correct choice of a constant voltage power supply, and a suitable cross-section of the wires used in installation.
• Taking into account power derating is critical for stable operation over the designated temperature range. ‘Derating’ refers to the reduction of the output power depending on the ambient conditions.
• 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.

Warning!

• Using CBU-PWM4-4-LR with maximum load will make it hot. Make sure to place the product in well-ventilated space and away from any flammable material.
