The PP610 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
0.25mA steps below 1A and in 1mA steps above 1A.
Three modes of operation are provided separately for each channel:
Continuous:
In continuous mode the output is a continuous current.
Selected Continuous:
In selected continuous mode one or both inputs can be used to select an
output current. For each state of the inputs, the output current is fixed.
Strobed:
In this mode output is pulsed once per trigger. One input is used as a
trigger. The delay and pulse duration can range from 20µs to 1 second in
20µs or 2ms steps.
The PP610 can be set up using four push buttons and a four digit seven-
segment display (see
). The PP610 can also be set up
using commands sent over its RS232 connection (see
).
Configurations are saved in non-volatile memory so that the PP610 will
resume operation after a power cycle.
