MADE IN USA.
The 3 amp selectable test load may be used to test a diode driver for proper current output and waveform before being attached to an LED or laser diode. The test load simulates the voltage drop (Vf) of a diode at a given current (A). Voltage drops of 1.4 to 8.5 volts may be achieved using a jumper setting of 2 to 10 diodes. This range is sufficient to cover all normally used optical diodes. Note: This product is fully assembled, not a kit.
The selectable test load is shown in the photos in a suggested setup with a digital oscilloscope (optional). Click here
