(*1) Onboard over-voltage protection scheme protects fill light, Wiegand power output against high-voltage faults. The lockout threshold varies from 12.4V to 12.8V as the temperature varies.
However, the main system still maintains normal operation in over-voltage condition.
Onboard surge protection device protects the system against surge damage from power supply.
DO NOT USE A POWER SUPPLY HIGHER THAN 16V OTHERWISE WILL CAUSE DAMAGED TO BOTH THE SYSTEM AND THE POWER SUPPLY.
(*2) A 3Amp fuse used as over-current protection.
(*3) The characteristic impedance of the data cable should be 120Ω according to the TIA/EIA-485 standard.
