PP520 LED lighting controllers - User Manual
8.1
Triggers
The PP520 triggers are opto-coupled as shown in the circuit below. A
V
TRIG
voltage between 4.5V to 24V provides a logic 1 and any V
TRIG
voltage below 1V, a logic 0. Typically the value of V
F
is 1.5V.
8.2
Ethernet
The RJ45 connector fitted to the PP520 requires a straight through cable
to connect to a network switch, hub, or router. It runs at 10Mbits per
second.
8.3
Wiring
Refer to
(or
, or
) for important guidance on wiring up your PP520.
Ensure that the wire gauge used for these connections is appropriate for
the current to be drawn. Ideally, wires should be double crimped or
independently secured to ensure they cannot come loose. Route low
voltage and mains wiring separately. If they must be loomed together
ensure that low voltage insulation rating is sufficient or that supplementary
insulation is used.
Note:
The case of the PP520 is not connected to the GND supply
connection.
8.4
Power supply
Refer to
(or
, or
) for important guidance on selecting a power supply for your
PP520
Power supplies should be regulated with SELV compliant outputs (fault
tolerant). Consideration should be given to fusing. The fuse value can be
based on the average current output.
Note:
In Europe, fuses are designed to pass at their rated current, while in
the USA fuses are designed to blow at their rated current.
