PFC - Power Factor Correction is a method by which an inductance is inserted
into the input circuit of a power source to improve the power factor and overall
efficiency of the system.
Phase Angle - the degree of measurement that corresponds to an AC
waveform’s amplitude. Measured from 0 – 360 degrees.
PLC - Programmable Logic Control is an automation method using relay or
digital technology.
Polyphase Mode – the 400XAC AC power sources can be configured to provide
output voltages of up to 600VAC (output configured for 1Φ3W) or provide 3Φ
output power (output configured for 3Φ4W).
Power - A generic term used to describe electrical work being done. There are
many types of power, including real power, reactive power, apparent power, and
complex power.
Power factor - The ratio of real power (watts) to apparent power (VA). Based on
a scale from 0 to 1 to determine how reactive and resistive a load is.
Reactive Power – the power absorbed by capacitive or inductive elements in a
circuit. This power does no work. Measured in VAR (volt-amps reactive).
Real Power – the power that performs work in a circuit. Measured in watts.
Response Time - The time that is needed to regulate the voltage, current,
frequency, and power output when a load is added to the power source.
Safety Agency Listing - A safety mark given to a product that has met stringent
benchmarks as classified by the authorized agency.
SmartConfig – This feature allows the operator to change the output of AC
power source’s Polyphase (3Ø4W) mode to single phase (1Ø2W and 1Ø3W) or
DC mode with a simple button push. Changing the internal cables or dip switches
is not required.
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 output waveform.
