ROAL LED-Drivers

Roal is developing a new family of LED Drivers to power General Lighting LED fixtures.

Roal is developing a new family of LED Driver suitable for General Lighting, Wide Area Lighting, Architectural Lighting.
The family of LED Drivers consists of 8 different models.
Each device is designed to be configurable from 1 to 4 constant current outputs, and it is also suitable for R,G,B,W (Red, Green, Blue, White) color mixing applications.
The Input Voltage can be AC or DC. The output Voltage can be 24Vdc or 48Vdc allowing a wide LEDs choice. Each constant current output can deliver up to 2A.
Digital Control Versions use RDM (Remote Device Management) and allow the use with the DMX512 protocol.
Digital Control versions come fully equipped with LED temperature compensation.
Analog Control Versions allow the use with an existing traditional Dimmer (0-10Vdc)
These LED Drivers are robust, very flexible and easy to install and use.

Configurable 60W LED Driver

This family of LED Driver is fully compatible with a wide variety of LED Lighting systems.
Each device is designed to be configurable from 1 to 4 constant current outputs, and it is also suitable for R,G,B,W (Red, Green, Blue, White) color mixing applications.

With NO minimum load requirement, each Output Channel can deliver from 0 to 2A output current, according to the limit of the Total Maximum Output Power (60W).

Example of final Application: pendant Luminaire

AC Input Versions (ACxx-y) accept a wide range input voltages (115Vac, 230Vac, 277Vac), allowing world wide installations.
DC Input Versions (DCxx-y) accept 26Vdc or 50Vdc input from a suitable galvanically isolated source.

The entire family can deliver a constant current output with voltages from 12Vdc to 50Vdc.

LED Driver Output Connector

Versions with Digital Control (xxyy-D) use RDM (Remote Device Management). The RDM permits addressing for each output channel and is fully compatible with DMX-512. Digital Control versions come fully equipped with LED temperature compensation.
Versions with Analog Control (xxyy-A) allow their use with existing traditional Dimmer (0-10V), performing a smooth dimming control of each output channel.

These LED Drivers are robust, flexible and easy to use.

Roal is developing the following Models and the products release is expected by the end of the 2008.
