In addition to a maximum current, these drivers also have a corresponding maximum voltage that they are capable of supporting, so both specifications must be taken into account when determining driver compatibility with a given LED. Preset current ranges and the associated maximum available forward voltage are given in the table to the right. LEDs with a forward voltage smaller than the stated maximum voltage for the drive current are compatible.

Therefore, the Therefore, the 5. In actuality, the maximum possible forward voltage will scale inversely with the amount of current supplied by the driver: higher currents result in lower maximum forward voltage values that the driver can support before being damaged.

The three graphs below provide examples of the actual measured maximum voltage provided by a DC driver for three of the preset current ranges on the LED1 terminal: 2 A, 4 A, and 10 A. The exact performance will show some variation between drivers, but will always be within the specifications stated above. The DC20 is a basic option that allows users to control the intensity of their LED using a control knob on the top or via an external TTL signal for modulation.

For more advanced applications, our DC drivers provides a touchscreen interface that allows users to control the LED current, select internal or external modulation modes, and more. The table below provides a comparison of key controller features. The connector is a standard M8x1 sensor circular connector. Pins 1 and 2 are the connection to the LED.

Pulse Mode This mode operates using rectangular pulses to modulate the drive current, but allows the user to set the LED parameters in a different way. Internal Modulation Mode For applications requiring more than simply switching the LED on and off, this mode allows the LED current to be modulated using either a sine, square, or triangle waveform. External Modulation Mode For more demanding applications, an external modulation signal can be applied via the SMA connector on the rear panel of the driver, which accepts input from 0 to 5 V.

The DC is a DC current source similar to usual laser diode drivers. Laser diode drivers usually have less noise on the current, especially those designed for lower current levels. But theoretically the DC can also be used to drive laser diodes.

The DC is however designed for the operation of LEDs and therefore might not have all the necessary laser safety features to comply with the regulations in your country. Therefore I would definitely recommend to get the approval of the laser safety officer in your facility before using it to drive laser diodes.

I will also contact you directly to provide further assistance. What are the rise and decay time of the LED when using the pulse mode? Thank you very much for your inquiry. However, it always depends on the settings used, the modulation mode and the current. I have contacted you directly to discuss further details. Hello I got a DC power supply loaned. I want to test it for my application.

I connect an output load of 8. My problem is that the max forward voltage is reached for a current value lower than mA.
