Description
The board is fitted into the NVR enclosure in place of the bundled power supply board, so the NVR can run from a low-voltage source. Without an installed jumper the device operating voltage range is 8–16 V⎓, with a turn-on threshold of 8 V⎓ and a turn-off threshold of 6.5 V⎓; with the jumper installed the figures are 12.1–16 V⎓, 12.1 V⎓ and 10.35 V⎓, and maximum current consumption is up to 4 A in both cases. The output is rated 12 V⎓ ± 3%, with a current consumption of 110 μA when shut down, 65 mA quiescent and 2 A maximum. Power is connected through a 0.26″ × 0.08″ connector slot and a 0.22″ × 0.08″ connector, for cable cross-sections of AWG 12–14. The board measures 4.64″ × 4.84″ × 0.67″ and weighs 1.80 oz, carries protection class IP20 and operates from 32 °F to 104 °F at up to 75% humidity.
