Direct Current Regulator (DCR)

The DCR (Direct Current Regulator) Lighting Controller powers the VISTA system, delivering a 1.4A current.

There are various options that can be pre-programmed inclusding the radio control pack that can be operated from the aircraft, please ask for more details.

Since the LED is a low current device there is no need for 6.6A circuits that should be converted to much lower amperage for LED usage. Moreover, the LED being a direct current device, the power distribution circuit is greatly simplified using a DC constant current power supply. To cope with this new requirement, and following their policy of constant innovation, ALS have developed a new concept based on a Constant Current DC Power Supply unit delivering a 1,4 Amps instead of the traditional 6.6 Amps. The 1,4 Amps value is the best suited for LED lighting engines eliminating the need for sophisticated and fragile electronics inside the light fitting. This concept also eliminates the need for series circuit transformers with their losses and expense, a specific device ensuring the continuity of the circuit upon failure of any single light unit is provided.
