    1.2 Glossary of Terms Alternating Current (AC) - Current that reverses direction on a regular basis (usually 60 times per second in the United States). Measured in amps. AC Power Source - An instrument that takes one AC voltage and frequency level and converts it into another AC voltage and frequency level.

  • Page 7: Safety Symbols

    Safety Agency Listing - A safety mark given to a product that has met stringent benchmarks as classified by the autho- rized agency. Steady State Current - A term used to describe the current when the load is running nominally after the inrush current. Switching Power Source - A power source that uses switching technology (integrated circuits and components) in order to generate the AC voltage, current, frequency, and power.

    3.2 Output Power, Power Factor and Output Current Considerations The reactive output power specification of APT 8500 series, models 8505, 8512, and 8520 change depending on the power factor of the load. While the 8505, 8512 and 8520 are specified as 400VA, 800VA and 1.6kVA units respectively, they can actually output up to 25% more reactive power based on the power factor of the load, thus keeping the real power under the specified limit.
