The Orcave 303-111 LampDriver is a small plastic box with cable grommets on the longer sides. Under the grommets, there are elongated "ears" on the box with holes for attaching screws or facets, for example, to the terminal board in the column. The box is made of black ABS with an information label on the face, and the electronics inside are covered with a waterproof material.
The source is designed to power and control lights that work with a DALI ballast. Examples can be Miracle lamps in the Advanced design or quite common lamps from other manufacturers on the market. The main benefit of this power supply lies in the ability to communicate with the switchboard (application) through the power line. The control of the appliances is therefore not dependent on a wireless solution, which is inappropriate for the critical infrastructure of the city.
The electronics of the source in its standard design can control not only lights with DALI, but also with an analog communication solution of the 0 - 10V type or the less frequently used phase communication of the PWM type.
The capabilities of the source are expanded by the possibility of detecting an analog signal in the range of 0 to 20V, or a universal input/output digital port 0 - 15V.
Usually, the source is installed at the terminal block at the foot of the column (it fits even in narrow sockets), which is advantageous during installation and possible service. However, it is also possible to build it directly into the light fixture, if the design of the light fixture allows it. This solution is interesting, for example, for lighting fixtures that are installed on concrete columns.
