Unlike other so-called fanless POS terminals, the KS Series does not use liquid cooling or heat pipes. Instead, the Fan-free KS Series has been designed and built from the start to provide the very best combination of cool running, high performance, low maintenance, and long life. Its patented heat dissipation design provides higher reliability, more user convenience, quieter operation, fewer service calls, and significantly less chance of “out of service” interruptions. And that translates into happier customers.FeaturesFan-free designSpill proof water resistant structureEasy maintenance constructionVertical type LCD panel with tilt angle adjustment from 15° to 70°High quality 15” TFT active matrix LCD panel with 1024x768 resolution (XGA),17” TFT active matrix LCD panel with 1280x1024 resolution (SXGA)Preprogrammed timer wake up functionCOM port MODEM ring up functionDurable resistive type or IR type touch sensor.Software control touch sound.Built-in UPS function(battery is option)Accidental power off protection and software managed power switch.LCD panel brightness also can be controlled by hardwareWall-mount option
