General Description

The PP860 current controller provides repeatable intensity control of LED

lighting for machine vision applications. It includes the power supply, intensity

control, timing and triggering functions required for machine vision systems.

LED lighting needs a constant current supply as small variations in voltage can

cause large variations in light output. Currents can be specified in 0.1A steps.

Two modes of operation are provided separately for each channel:

Continuous:

In continuous mode the output is a continuous current.

Strobed:

In this mode output is pulsed once per trigger. One input is used as a

trigger. The pulse width can range from 0.1us to 2ms in 0.2us steps. The

delay can range from 5us to 2ms in 0.2us steps.

Triggers occur on the leading edge of the input, that is on the transition from a

logic 0 to logic 1. Output 1 is triggered from INPUT 1, output 2 from INPUT 2,

etc.

Configurations can be saved in non-volatile memory so that the PP860 will

resume operation after a power cycle.

The pushbutton on the side of the unit is currently unused.
