The condenser’s installation and operation are identical to large electric motors and generators (some generators are actually designed to be able to operate as synchronous condensers with the prime mover disconnected [2]). Increasing the device's field excitation results in its furnishing reactive power (measured in units of var) to the ...
AKG C451B small-diaphragm condenser microphone RF condenser microphones use a comparatively low RF voltage, generated by a low-noise oscillator. The signal from the oscillator may either be amplitude modulated by the capacitance changes produced by the sound waves moving the capsule diaphragm, or the capsule may be part of a resonant circuit ...
C535 - a high-quality condenser vocal microphone. AKG made a gold-plated one for Frank Sinatra. [25] D409; D5; C1000S microphone. C1000S - a small diaphragm condenser (four versions released from 1986 to 2012) C2000B - a side-address, small diaphragm condenser; C3000(B) - a large diaphragm condenser (five versions released from 1993 to 2012)
All microphones made by Schoeps employ traditional (i.e. externally polarized, not electret) condenser transducers, and use small-diaphragm, single-diaphragm capsules, even in microphones which offer two or three different directional patterns. All models introduced since 1973, as well as some models from even earlier, have featured ...
A thermal expansion valve is a key element to a heat pump; this is the cycle that makes air conditioning, or air cooling, possible.A basic refrigeration cycle consists of four major elements: a compressor, a condenser, a metering device and an evaporator.
It’s many years since ISIS, also known as Islamic State, held sway over much of Syria and northern Iraq a time when it spawned affiliates throughout Africa and Asia and organized a series of ...
In vector control, an AC induction or synchronous motor is controlled under all operating conditions like a separately excited DC motor. [21] That is, the AC motor behaves like a DC motor in which the field flux linkage and armature flux linkage created by the respective field and armature (or torque component) currents are orthogonally aligned such that, when torque is controlled, the field ...
