2.2 Power Supply connections
The 'ISPnano Series 3 ATE' programmer requires a separate +12V power supply to power the
RELAY coils.
Programmer Power Supply
+9.0V to +24.0V @ 150mA

Instructions:
Connect a +9.0V to +24.0V power supply to the 'DC IN' connector.
•
Connect a +12.0V regulated power supply to the 'DC EXT' connector.

2.3 Programmer Power Supply recommendations
The 'DC-IN' connector is used to supply power to the internal programmer electronics. If the
programmer is not powering the Target System, then the programmer will only draw around 150mA
@ 9.0V. However, if the 'Programmer controlled Target Power Supply' is enabled, then the
programmer will also supply power to the Target System which could take a significant amount of
current. It is therefore recommended that a suitable power supply capable of supplying at least
500mA on load is used.
Although the 'DC-IN' connector is rated for any voltage from 9.0V to 24.0V, it is recommended where
possible to use 12.0V instead of 24.0V. In the event of a short circuit or other problem, the
programmer over-voltage protection will better protect the internal electronics if the supply voltage is
only 12.0V.
