What is a load box? Private2 months ago - Real estate - Bāli - 20 views
The electronic term that describes the speaker cabinet with respect to the amplifier is the “load”: we say the cabinet “loads” the amplifier. The term “load box” fits any product that embeds an electronic load. The main parameter of the load box is its impedance, and that is rated in “Ohms”. An 8-Ohm load box must be plugged to the 8-Ohm speaker output of the amplifier.
When using a Torpedo load box, the power sent to the load is turned into heat, so please follow the cooling recommendation of the load box – failure to do so may cause overheating which can lead to damage, both to the load box and to the amplifier. The Torpedo Reload, Live, Studio, Captor and Captor X are load boxes. This term indicates that these products feature a load which can electrically replace the speaker cabinet while safely dissipating (transforming into heat) the power coming out of the amplifier.
High voltage test
The high voltage tester (also called dielectric strength test or hipot test) can be carried out using AC or DC. If the high voltage test is performed using DC, it is then combined with insulation; if the high voltage test is made using AC, this is more stressful for the sample and therefore carried out according to the sketch below.
Measurement of a high voltage test under alternating current is performed using an alternating voltage (50Hz) adjustable to an effective 50V to 1,500V. As is the case with direct current, the high voltage test detects any sudden rise of current up to a programmed threshold.
Signal generators are of five major types: oscillators, which generate sine waves useful in measuring the response of loudspeakers, amplifiers, microphones, transducers, and acoustic systems; standard signal generators, which generate sine waves over a wide range of output power and modulation, used, for example, to test radio receivers and measure gain, bandwidth, and signal-to-noise ratio; frequency synthesizers, which generate highly precise output frequencies over wide ranges; pulse generators, which produce pulsed signals at precise duration at precise frequencies; and random-noise generators, which produce a wideband noise for various types of electronic, mechanical, and psychological testing.
Power analyzer measurements
Power analyzers can make a variety of measurements dependent upon the manufacturer and the model, but typically power analyzers are likely to be able to measure parameters including: voltage; current; power; peak, mean and RMS parameters; harmonics; phase, and a variety of other parameters.
Some power analyzers are intended for high power measurements and may even have special high power sensors, whereas others may be intended for measuring the standby current parameters for various items of equipment.
