Reference information
10.1 Timings
Switched mode:
The maximum delay from a trigger input changing to the
output current being turned on or off is 10μs.
Pulse Mode:
For the PP500F the minimum pulse delay is about 4μs.
10.2 Specifications
Parameter
Value
Notes
Digital supply voltage
(PSU+)
12 - 48VDC
regulated
Must be at least 1V greater than the load
potential difference at maximum current.
Quiescent current
150mA
This is when using a 12V supply; the
current is lower at 24V.
Input enable level
From 3V to 24V
This is the voltage applied between
+ and − of each input.
Input disable level
< 1V
See above.
Typical trigger input
current
3mA at 3V to
24V
Max output current per
channel
2A continuous,
10A pulsed
Maximum total average
output current
2A
The average current for all channels
added together must not exceed this.
Ambient temperature
during operation
5°C to 40°C
The ambient temperature may need to be
lower if the PP500 is dissipating a lot of
heat.
Total allowed power
dissipation without heat
sinking (P
D
)
8W maximum

PP500 LED lighting controllers - User Manual
10.3 Error codes
Error
number
Reason
PO
Internal power dissipation is too high. Output turned
off.
OP
Output current to lighting is too low.
OP
There is not enough supply voltage for the requested
output current.
SH
The output is short circuit.
HI
The voltage required for the lighting has increased too
much. Check for ageing of the lighting or a failed LED.
LO
The voltage required for the lighting has decreased
too much. Check for ageing of the lighting or a failed
LED.
FAt
Fatal:
The PP500 is too hot. The PP500 is fitted with a
thermal cut-out. If the internal temperature reaches
62°C (corresponding to a case temperature of 70°C),
the outputs are turned off. This message is displayed
until the PP500 has cooled down to below 62°C.
FAC
Fatal:
One channel is producing more output current
than expected.
