Setting Accuracy The ability to accurately set a knob, switch, or other adjustment to the time delay, or other monitored parameter.
Snubber Network A form of suppression network which consists of a series connected resistor and capacitor connected in
parallel with the output device. Helps to limit the maximum rate of rise of a voltage. Used to prevent false
turn-on of solid state outputs.
Snubber A resistance/capacitor or diode/resistor circuit used to dissipate transient energy peaks.
Transducer A device for converting an electrical signal into a useable direct current or voltage for measurement purposes.
RMS The effective value of alternating current or voltage. The RMS value equates an AC signal to a DC signal which
provides the same power transfer.
True RMS Amps The effective value of an AC signal. For an amp signal, true RMS is a precise method of stating the amp value
regardless of waveform distortion. An AC measurement which is equal in power transfer to a corresponding DC
current.
True RMS Volts The effective value of an AC signal. For a voltage signal, true RMS is a precise method of stating the voltage
value regardless of waveform distortion. An AC measurement which is equal in power transfer to a
corresponding DC voltage.
Unbalanced Loads Refers to an unequal loading of the phases in a 3 phase system (current and/or phase angle).
Watt Unit of electrical power. WATTS=E*I*PF
VA The product of the RMS voltage applied to a circuit and the RMS current, in amperes, flowing through it.
VAR(Volt-Amperes Reactive) The unit of reactive power as opposed to real power(watts).
