Reference information
13.1
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 PP520F the minimum pulse delay is about 4μs.

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 4.5V to
24V
This is the voltage applied between
+ and − of each input.
Input disable level
< 1V
See above.
Typical trigger input
current
3mA at 4.5V
22mA at 24V
Max output current per
channel
2A continuous,
10A pulsed
Ambient temperature
during operation
5°C to 40°C
The ambient temperature may need to be
lower if the PP520 is dissipating a lot of
heat.
