Overview
The CH93 series, part numbers 6420093-( ), is a multi-function digital
clock / chronometer / voltmeter / temperature unit with multiple options
for USB Charging Ports. The unit fits into a standard, rear-mounted,
2-¼” avionics panel cutout. Power is drawn from the aircraft main bus to
light a white, six digit, seven segment LED clock. The clock can
display several different modes: local time, universal time, flight
timers, elapsed and countdown timers and optionally, bus voltage and up
to two temperature inputs. The CH93 display is daylight readable with
two methods of brightness control. It can be controlled automatically
using the internal photocell or manually with an external dimming bus
voltage. The CH93 clock has an internal battery to maintain clock time
and flight timer memory when the aircraft is not in use.
The USB Charging Ports are designed as DCPs (Dedicated Charging Ports)
to industry-standard protocol per the USB Battery Charging 1.2
Compliance Plan. Some models also comply with the higher power
requirements of USB Power Delivery 2.0 and 3.0. Early-generation or
smaller consumer electronics typically accept one (1.0) amp during
charging. However, newer electronics, such as tablets and larger devices
can accept, and in some cases, require up to 3 amps to charge and
operate.
