Under the situation of global energy shortage, greatly developing new forms of energy and energy savings is the effective means of increasing income and decreasing expenditure that we must take. Solar street light is to utilize the street lamp of solar energy photovoltaic power generation module as power supply, and it has directly utilized solar energy; And the LED luminous product as the 4th generation lighting source, its luminous efficiency is very high.So solar LED street lamp has been gathered both advantages, under the embarrassed shape of the present energy, very far-reaching development prospect is arranged. But in present practical application, it is low excessively then the solar LED street lamp charge efficiency to occur through regular meeting, and the life of storage battery is too short, and can not effective monitoring to the working condition of each street lamp, like operating time, degree of aging, operating current etc.This has increased the maintenance cost of street lamp greatly, also will reduce the municipal efficiency of management.
Some questions about power supply noise and transducer wiring
Your CM ground has an output impedance of 510 Ohms with the sensor being 1K but load current for the MEMs accelerometer "may" be fairly constant. (verify) Otherwise Load regulation of supply may affect noise floor, if important.CMRR depends on frequency of interference and impedance ratio of load to source for CM attenuation and balanced cable and Diff impedance help. Ferrite chokes and shunt caps will help with AM/SW interference on long cables. (AM Antenna effects).Is there a DC offset needed for gravity? or is this just for structural vibration?Supplies 20mA virtual centre V gnd to 10mA sensorFor apps needing more current using an Op Amp to drive the emitter follower pair with direct feedback and split rail RC on Vin works.Dual Batteries are good for lower ESR, high surge currents but also generate more thermal noise easily filtered for analog situations.
Changed out power supply but computer still immediately turns off after it is turned on, whats wrong?
Sounds like something on the motherboard is screwed up. I had a similar problem and ended up replacing just about everything
how to measure the characteristics of regulated power supply?
That is a good answer, except you need a variable or adjustable power resistors, so you can have 10 or 20 points on a graph, to show the load voltage (and ripple voltage) at various load currents
What does the US power supply waveform look like?
AC power is nominally a 60 Hz sine wave, but it may be somewhat distorted, depending on loading. We normally speak of the Root Mean Square (RMS) voltage of AC. The peak voltage is about 1.4 times the RMS value.Normal domestic power is single phase, but the overall power distribution system is three-phase.
will a 500w power supply be enough for my current computer setup/ rig?
1.) If your PC does not have enough power, it wo not hurt your hardware. 2.) The 450W minimum it determined with top of the line hardware (usually with a quad-core xeon processor). Even though you a running it a little bit close, I think that it should run it just fine. Besides, most people buy a PSU that much more powerful than what they need, and end up wasting money on unneeded watts.
Truck won't start again. It's gotta be a power supply issue1?
Truck & 365 days? what is the Voltage interpreting on the Battery? (could by ability of 11V to twelve.5V) Does the Engine Crank? Have the Alternator "Load examined" to be certain if it places Out the listed Amperage, Low Amps ability undesirable Diode(s) and it will Drain you battery
Are my power supplies compatible?
Desktop wise, if it fits in the case and the connectors fit, it will be fine. There are exceptions: Is if the computer seeking the power supply has a high power demand. This is usually only the case if powerful graphics cards are connected (they hook up directly to the power supply). Worse case scenario is that you could damage the power supply if you try to drag out too much power from it. Are ALL of the required connectors present? The motherboard connector can be 20 pin or 24 pin, but usually a 20 pin will work fine even in a 24 pin socket. You will also need a separate 4 pin connector that plugs in near the processor. You need enough connectors for your drives, including SATA power connectors if you have SATA drives. If you do not have the required connectors, they can be bought cheaply online. Hope this helps, Dave
