11. Power supply requirements
The driver requires a 5V DC power supply. The power supply must be able to cover the driver
and TEC output power and losses. The power supply must provide 20W or more (it depends on the
driver version) and line regulation ± 1%. Recommended power supply: Mean Well RS-35-5.
ATTENTION! Do not use any relay between power supply and driver. When using a relay, voltage
surges may occur and driver may fail.
