8. Power supply requirements
The driver requires a DC power supply with line regulation ± 1%. The power supply must be able
to cover the driver output power and losses. Nominal input voltage 12V. Recommended power supply:
Mean well HRP-450-12.
ATTENTION! Do not use any relay between power supply and driver. When using a relay, voltage surges
may occur and driver may fail.
