The devices below are a few of the products designed
and manufactured by Tri-L Electronics since it started in 1965. |
|
A Police and fire radio converter. Set it next to an
AM radio and receive police and fire calls. This converter was very popular
in the cities during the riots of the late 60’s. |
|
The 70’s we manufactured broadcast equipment, at the
right is a portable mixer amplifier used to mix microphones to a video
recorder and was carried by news crews. Radio broadcasters used this device
on phone lines for athletic events. We also built magnetic strip camera
recording amplifiers. Our amplifiers went with the news crews to cover
President Nixon’s trip to China. |
|
The device to the right is a shift control unit that connects to a computer and drives the shift motor on the assembly line for 4 wheel drive transfer cases. This product was designed in 1996
and is still in production. |
|
Above is the Travel Charge. This battery charger was
designed to charge handicap scooter batteries from a 12V automotive system. It converts
the 12 v system to a 24V battery charger with over charge protection and
automatic shut down when the vehicle is not running. It has potted
construction and will operate under water for out side of vehicle use if
needed. |
|
This unit is a vacuum alarm used with radon removal
equipment. We have built it since the early 1990’s and is still in
production. |
|
This is a carrier detect and delay to prevent the
911 systems from shutting down due to line glitches. Phone companies have ordered these since 1995 and
they are still in production. |

Tri-L Electronics wrights software for machine
control and other business applications. For example a Centrex billing system
for government and business, phone bill control. A bank deposit system to
replace the deposit book and store all credit card, checks, sales tax and
category of sales deposit data. This data is printed on an 8.5” X 11” page in
landscape format. The paper has a perforation down the left end so when
separated the small end is the same size as a deposit slip with the magnetic
ink account number. The deposit data is printed down the deposit slip and
repeated on the depositors portion just to the right of the perforation. The
check, credit card and category data is printed on the depositors portion.
This software has been very successful for Wisdom Dock since 2000. |
