Overview

The CH93 series CHRONOS Digital Clocks are a multifunction clock which displays volts, temperature, time, countdown time, and stopwatch, and also comes available with multiple USB charging options. The CH93 installs in to a 2-1/4 inch avionics panel cutout and power is drawn from the aircraft main bus to power the unit. The white, seven-segment LED clock can displays several modes: local time, universal time, flight timers, elapsed and countdown timers and optionally, bus voltage and up to two temperature inputs. The daylight readable display features two methods of brightness controls: automatically using the internal photocell or manually with external dimming bus voltage. An internal battery maintains clock time and flight timer memory when the aircraft is not in use.
