سؤال: What is the RMS power?

السؤال بواسطة pdsburg على 2021-10-25 05:28:50

thatslife78 seen on internet, first choice : Mean power, or root mean square (RMS) power handling, refers to how much continuous power the speaker can handle. ... For example, a speaker with a 30W RMS rating but a peak rating of 60W means that speaker can comfortably run with 30 watts of continuous power, with occasional bursts of up to 60W. SO : RMS is the continuous power affordable without burning anything . BUT ( to me, as far as i know) : for an AMPlifier, the affordable current REALLY dispatched in a speaker is : current divided by resisting power of speakers : 26 volts divided by a 4 ohms speaker means ...6.5 watts At first try to find a power supply : you may find 75 watts not 75x2 which is what you need for a stereo system.....

سؤال: the two phase means 0 and 180 phase angle output?

السؤال بواسطة pdsburg على 2021-02-24 01:29:38

canaverdejose Two phase means 2 coils on the stator. Coil A and coil B. A two phase bipolar motor has 2 groups of coils. A 4 phase unipolar motor has 4. A 2-phase bipolar motor will have 4 wires - 2 for each phase. Some motors come with flexible wiring that allows you to run the motor as either bipolar or unipolar. Bipolar motors have a single winding per phase. The current in a winding needs to be reversed in order to reverse a magnetic pole, so the driving circuit must be more complicated, typically with an H-bridge arrangement (however there are several off-the-shelf driver chips available to make this a simple affair). There are two leads per phase, none is common. A typical driving pattern for a two coil bipolar stepper motor would be: A+ B+ A− B−. I.e. drive coil A with positive current, then remove current from coil A; then drive coil B with positive current, then remove current from coil B; then drive coil A with negative current (flipping polarity by switching the wires e.g. with an H bridge), then remove current from coil A; then drive coil B with negative current (again flipping polarity same as coil A); the cycle is complete and begins anew.

BG101524152 Thereis only one channel - the generator chip can support balanced output and the board designers have taken advantage of this to provide two outputs. I haven't looked at using these as a balanced output - if you want to do this you need to use phase-matched (equal length) cables.

سؤال: Output impedence? what kind of speaker can it drive?

السؤال بواسطة pdsburg على 2021-01-21 08:19:38

pacoul The TDA2030 is a monolithic integrated circuit in the Pentawatt® package, intended for use as a low frequency class-AB amplifier. Typically it provides 14 W output power (d = 0.5%) at 14 V at 4 Ω. At ±14 V or 28 V, the guaranteed output power is 12 W on a 4 Ω load and 8 W on an 8 Ω (DIN45500). So, 4 to 8 ohms, probably more.

سؤال: What is the max current output?

السؤال بواسطة pdsburg على 2020-06-17 10:13:28

chadcoldfusion I wouldnt go over 0.089 Amps due to the internals mostly being ICs that are not replaceable and heat sink with a fan to cool off the loaded circuit. It's best to have an external driver circuit with a bnc female connection that's fairly isolated to drive any current and frequency to a circuit. If you need some wave output just use driver transistors rather than mosfets
