Glossary
Capacitor
A component that stores electrical charge. Capacitance is measured in
Farads. Used to store energy to be discharged into the flash tube.
Choke / Inductor
A device consisting of a coil of wire. An inductor opposes the flow of AC
and variations in the flow of DC current. Used to protect flash tube.
Flash tube
Three terminal device which consists of a glass tube filled with xenon gas.
The tube contains two electrodes across which a voltage is applied and a
third electrode used to trigger the tube.
Fuse
A protective device for electric circuits containing a wire designed to melt
and open the circuit under abnormally high electric loads. Used for
incoming power, sidelights and PEC.
MOV
Metal Oxide Varistor. A device used to protect sensitive components from
voltage transients. Used throughout the equipment.
Relay
An electrically controlled mechanical device that opens and closes electrical
contacts when a voltage (or current) is applied to a coil. A relay provides
isolation of control signals from switched signals. Used to switch from day
to night mode, discharge capacitors, control transformer and provide alarm
contacts.
Resistor
An electronic component that opposes the flow of electrical current.
Resistance is measured in Ohms. Used in night circuit.
Terminal Block
An insulating base with binding posts to make connections where sets of
terminals are mounted. Use to connect flash head cable, power, sidelights
and PEC.
