LED Drivers

Doric programmable LED Drivers are available in one-, two-, and four-channel versions. When connected to an LED module having an eprom memory, the LED Driver recognizes the module wavelength and automatically sets the maximum current value to avoid accidental overdriving.

Doric programmable LED Drivers are available in one-, two-, and four-channel versions. When connected to an LED module having an eprom memory, the LED Driver recognizes the module wavelength and automatically sets the maximum current value to avoid accidental overdriving.

In stand-alone mode, all LED Drivers allow cw operation, external TTL and external analog modulation through an input BNC connector for each channel. There is also a current monitoring BNC output for each channel allowing data acquisition or triggering of other devices. When using Doric Neuroscience Studio Software, more advanced operating modes are available such as: TTL modulation and software defined illumination sequences. In low-duty cycle pulsed mode, the software allows to overdrive the LED sources if a higher power is needed. For multiple channel driver versions, each channel is controlled independently. Although not mandatory for LED sources, our LED Drivers come with a safety interlock connector and a main key switch. These eye safety features are of interest for UV and near infrared LEDs.

Note: The renewed line of Doric LED Drivers has a new connector pinout that does not include pins for fan power. It is thus essential to use a Fan Power Adapter (FPA) when using Connectorized Multi LEDs or Multi LEDs + Fiber-optic Rotary Joints. This power adapter is suitable for up to 4 channels and is sold with corresponding M8 cables.

    One way of getting around connection losses is to integrate the LED or LEDs in the fiber-optic rotary joint, thus eliminating one fiber patch cord all-together. That is exactly what we did by joining a fiber-optic rotary joint and an individual LED or cluster of LEDs.
