• The
Interlock Connector Plug
(Fig.
) allows the user to connect the driver to an interlock system. It is recom-
mended to connect the interlock plug to a laboratory interlock system. This is critical when using LEDs in the UV
or Infrared spectrum, as they are invisible to the naked eye.
• The
Input BNC
allows the control of the LED driving current of the corresponding source with an analog or TTL
signal.
• The
Output BNC
are used to monitor the driving current of the corresponding light source.
• The
12 VDC power input
connects the driver to its 12 VDC power supply.
• The
USB-B Connector
allows the driver to be connected to a computer using a USB-A/USB-B cable.
• The
On/Off switch
