1. Technical data and requirements

Universal Trip C mputer (UTCOMP) developed and manufactured by REVELTRONICS is an on-board computer designed for wide range of

vehicles. It takes information from main sensors then process data and sends to LCD or OLED screen with user friendly interface.

Technical parameters

•power supply from 12V or 24V installation (safe range: +8… + 2V DC),

•power consumption in standby mode: 4-12mA@12V (typ. 8mA@12V),

•power consumption in idle mode: 40-500mA@12V (depends on used display, brightness, connected sensors etc.),

•operating temperature: -40C…+85C,

•LCD operating temperature: -20C...+70C (recommended +10C...+40C),

•OLED operating temperature: -40C...+85C,

•digital temperature sensors measurement range: -55C...+125C, accuracy 0,5C, resolution 0,1C,

•vehicle speed accuracy: +/- 1km/h or mph (calibration possible),

•acceleration measurement accuracy: +/- 0,1s (for VSS constant < 0.2 [m/imp]),

•fuel consumption accuracy: 1% for petrol engines, 2% for petrol + gas engines, 1- % for diesel engines (calibration possible),

•sampling time of real-time fuel consumption: average from 1s, 2s or s,

•sampling frequency from analog sensors (measurements and alerts): 50Hz,

•analog sensors measurement accuracy: +/- 0,05V for UTCOMP- and +/- 0,02V for UTCOMP-PRO [V],

•voltmeter accuracy: +/- 2% range +/- 0,05V (calibration possible),

•supported units: km, km/h, l/100km, l/h, km/l, mil, mph, mpg, Celsius, Farentheit, bar, psi, volt,

•communication with PC and Android devices via USB 2.0 (HID).
