Candle-Power CP12

DISCONTINUED. This product has been superseded by candlePower octo.

Candle-Power constant current LED driver:

  • Fitted with 4 RGB modules (12 channels of dimming)
  • Current rating of 350mA or 700mA
  • Alternatively, buy the product with no modules fitted (then purchase modules separately to customize Candle-Power as desired)

Candle-Power™ CP12 is a constant current LED dimmer designed to control high power LED devices such as those available from Lumileds and Cree. The product is presented in a DIN rail case that allows rail or surface mounting; it is powered via an external power supply unit (15-48 VDC). We recommend the PSU-48-10-DR.

The standard Candle-Power CP12 is available with a choice of two current ratings: 350 mA and 700 mA. (1W LEDs are normally driven at 350mA and 3W LEDs are normally driven at 700mA). The product is fitted with 4 modules, each of which can control an RGB circuit. This gives a total of 12 channels of constant current dimming. Each of the 12 outputs can drive up to 12 high power LEDs in series, giving a total load capability of 144 LEDs.

Candle-Power can also be purchased with no modules fitted (product code CP12-0). The purpose of this is to allow customers to tailor the product for their needs, as the modules can be purchased separately (see CPM). For example, if you only need 3 channels of dimming, then one module fitted to a CP12-0 will suffice.

The control interface is DMX512 and RDM. All parameters (including start address) are set using RDM.  This can be done using an RDM programmer, such as Jump-Start.
