Dielectric: The insulating material between the plates of a capacitor.
Dielectric Constant (K):The property of the dielectric material that determines how much electric energy can be stored in a capacitor of a particular size by a value of applied voltage.
Dielectric Strength:The ability of a dielectric material of specified thickness to withstand high voltages without breaking down.
Diode:Any two-electrode device that conducts in only one direction.
Discharged:The removal of the charge in a capacitor by completing a circuit between the plates.
Displacement Current:The current flows in a circuit containing a capacitor whenever the capacitor charges or discharges.
Donor: A type of impurity that adds electrons to the atoms of a semiconductor substance.
Deep Cycle Battery: A battery designed to be routinely discharged to 20% of its maximum capacity without damage. These are the type of battery most commonly used with an inverter system.
Dip Switches: A series of small switches used for special programming of the Freedom Inverter/Chargers. These switches are located on the rear of the Freedom remote panel.
Direct Current (DC): Current that flows continuously in one direction such as that from batteries, photovoltaics, alternators, chargers and DC generators. The type of electricity stored in batteries that flows in one direction.
Depth of Discharge: The ampere-hours removed from a fully charged battery, expressed as percentage of rated capacity.
Digital Volt Meter (DVM): A voltmeter that incorporates an RMS (Root Means Square) converter to read true RMS for any waveform shape.
