Analog Clock - Electric
- Without backlight
I like the simple, elegant design of this analog clock. It fits into a standard 57 mm (2 1/4 in) instrument hole.
10 to 32 VDC power is required to keep it running. If you remove
your glider battery between flights, you'll need to reset the clock
before flight. But it is very easy to set. It requires only
3 mA of current. The back of
the unit states that it runs on voltage as low as 8 VDC.
Battery Tests
For use in a sailplane I was curious how long the unit would run with a
9V battery or 8 AA batteries. I bought a 9V battery connector at
Radio Shack. It ran continuously for 3+ weeks on a single 9V
alkaline battery. If you only connect the clock to the 9V battery
while flying, it should last through an entire soaring season easily.
I then tested it with a Radio Shack AA battery pack that holds
8 AA batteries (8 x 1.5V = 12V). It ran for more than 3 months.
