About Ballasts

Ballasts are power supplies or transformers for fluorescent lamps, light sources that consist of a glass tube filled with argon, neon, or other inert gas. When ballasts supply electrical current, the resulting arc emits ultraviolet (UV) radiation that excites the phosphors inside the lamp wall, causing them to radiate visible light. Basic lighting ballasts can be as simple as a series of resistors – a common configuration in small neon lights. Other types of ballasts include electronic ballasts, magnetic ballasts, fluorescent ballasts, high intensity discharge (HID) ballasts, and metal halide ballasts. Ballast manufacturers are located across the United States and around the world. They adhere to a variety of standards, including guidelines from organizations such as the American National Standards Institute (ANSI).

Power Supplies

Power supplies are devices that produce AC or DC power. This grouping includes current sources, DC power supplies, AC-DC adapters, DC-DC converters, AC power sources, and DC-AC inverters.

Programmable Power Supplies

Programmable power supplies are digitally controlled power sources that provide accurate and adjustable levels of voltage, current, and frequency. They include a processor, voltage/current programming circuits, current shunt, and voltage/current read-back circuits.

Single Phase Uninterruptible Power Supplies (UPS)

Single phase uninterruptible power supplies (UPS) sit between an AC outlet and an electronic device to provide power conditioning, back-up protection, and distribution for electronic equipment loads. They also prevent power disturbances from affecting the performance and life of the electronic device and vital data.

Specialty Power Supplies

Specialty or proprietary products and accessories related to power supplies.

Three Phase Uninterruptible Power Supplies (UPS)

Three phase uninterruptible power supplies (UPS) operate in conjunction with existing electrical systems to provide power conditioning, back-up protection, and distribution for electronic equipment loads that use three-phase power.
