3.4.3 Power Supply Guidance
The NV9 Spectral requires a stable 12 V DC / 3 A power supply. Check the power
requirements of the host machine and other peripherals to dimension a suitable
power environment for the machine setup.
Caution!
Power must always be connected.
TDK Lambda manufactures suitable power supplies. See table below for further
details.
