Reactive power describes the portion of electrical power that circulates in the system as magnetic or electric field energy.Reactive power increases the current load in the network without providing usable work.
Reactive Resistance
The reactive resistance – also referred to as reactance – describes the frequency-dependent resistance component of a device that stores electrical energy in magnetic or electric fields.
Regenerativ
Regenerative – Describes a property of devices, systems, and processes that enable energy recovery, feedback to the grid, or sustainable renewal.
Regenerative DC Load
A regenerative DC load is an energy-recovering electronic DC load that applies a controlled load to a DC source such as a battery, power supply or fuel cell. The absorbed energy is not dissipated as heat but efficiently fed back into the power grid.
Remote Sense
What is Remote Sense?
Remote Sense is a function in power supplies and electronic loads that is used
to compensate for voltage drops in the connection leads.
Resistance
The electrical resistance indicates the extent to which the flow of current in a circuit is impeded. The greater the resistance, the lower the current flow at a constant voltage.
Ripple Test
What is a Ripple Test?A ripple test refers to the measurement of the residual ripple of voltage and current in direct current sources such as power supplies, batteries, PV strings, or DC-DC converters.
RMS (Root Mean Square)
RMS (Root Mean Square / Effective Value):
Key figure for alternating quantities such as current or voltage.
The RMS value – also called the effective value – indicates which DC quantity would produce the same heating effect in a resistor.
RS-232 (Recommended Standard 232)
RS-232 = Recommended Standard 232.
Standardized serial interface for data transmission between two devices.
