How many watts is a sump pump?
Sump pump motors come in various sizes. To give an answer, the HP or voltage and amperage of the motor must be given. You may find the following formula useful. Watts = Amps x Volts.
Why do you connect capacitor in MAX232?
The input to the max232 ic will be of Transistor Transistor Logic (TTL) and its voltage range will be of 5 volt. The output of the max 232 ic will be of Recomended Standard 232 Logic (RS232 logic) and its voltage range will be of 12 volt. The max 232 ic which is operating on 5 volt supply has to step up the 5 volt input to 12 volt. Hence a capacitor is used for pumping the voltage and called as pumping capacitor.
How can you implement darlington pair using mosfet?
its not too hard... darlington transistors are simply a pair of bipolar transistors which allow for control of a significantly greater current or voltage (or both) via a low power signal such as a microcontroller. Frequently Transistors that can control a larger current or voltage require a higher gate voltage (Vgs) to fully turn on the transistor than the microcontroller is able to deliver so a smaller transistor is used to boost the control signal. You can build your own darlington out of a pair of bipolars - one that runs at logic level and boosts the signal to control the second one that runs at the higher current & voltage of the end device. The same can be done with mosfets. There are a fair number of mosfets that can control a decent current and voltage but in many cases you'll need to use either discrete boost (charge pump) mosfets, or a control chip that has built in charge pump circuitry. This is a fairly common requirement in building motor controllers and amplifiers which are or can be controlled by PWM or some other form of logic level signal. The international rectifier IR2104 is a good example of logic level mosfet that can be paired with a more powerful mosfet such as IRF540N for the actual current control. As mentioned you can also use a driver circuit such as those found in the HIP408x series which will obviate the need for a boost mosfet - this configuration is found in a number of commercial motor controllers including those by numerous wheelchair manufacturers.
How many amps does a 1.5 hp water pump take to start up?
To answer this question the voltage of the motor must be stated. I = W/E. 1 HP equals 746 watts.
Is there such thing as a sump pump connected to a generator?
Yes, a sump pump can be connected to a generator to make it operate. Keep in mind that the starting current of the pump motor could be 300% of the running current and the sizing of the generator should take this into account. If you are looking for the sump pump using a mechanical connection it will connect to the engine and not to the generator.
How do you convert 200uV to 9V without using transformer?
If the 200μV is AC, you can use a charge-pump ladder. This consists of a network of capacitors and diodes that incrementally increase voltage with each stage. For DC, you would need to use an oscillator, either together with a charge-pump ladder or as part of a switch-mode power supply.
How the voltage is being stepped up in the case of mobile chargers?
If,for example, a 12 volt car battery is used to charge an 18volt mobile battery then an electronic oscillator stacking voltages on capacitors via diodes is used. This is called a 'charge pump' or 'Cockcroft and Walton' voltage multiplier.
1984 RX7 12a-Fuel pump does not work I have voltage on the two blackwhite wires going into sol no voltage coming out The wire coming out of sol Bluewhite is not the same color as wire on pump blackwhi?
so you have voltage going to the pump but none or minimal voltage on the other side of the pump? definate dead pump. if you able to see voltage do a continuity test between the power and ground pins on the pump, if theres no continuity then you will know that you will need a new pump. cheers.
Wire to electric fuel pump has low voltage?
if you have checked the voltage with a dvom then you need to verify that the power source at the fuel pump relay is correct, if it has the correct voltage pre-relay then your problem is post-relay. if the voltage is not correct pre-relay then simply trace and repair the power source. if the problem is post relay then check the output voltage directly at the relay, if voltage is good trace and repair line from relay to pump. if voltage is not correct then replace the fuel pump relay
Does a fuel pump relay change the voltage to a fuel pump?
No, the fuel pump relay engages and sends voltage to the fuel pump. The fuel pump requires 12 V DC to operate properly. A fuel pressure test will verify the condition of the fuel pump.
What is the voltage on fuel pump 2000 jeep?
The pump runs on 12 volts.
What size wire for 50 amp 3 wire pump 350 feet?
This is a voltage drop question. To answer this question the voltage of the pump must be stated
How many amps does a 2 hp pump draw?
To answer this question the pump's voltage is needed.
Why isn t the car starting after replacing the fuel pump?
Check your fuel pressure. No pressure means the pump is not running or defective. Check for voltage at the pump harness and pump relay. If you have voltage and fuel pressure to spec, then you have some other issue, and the fuel pump is not the problem.
How much voltage is required to turn on the fuel pump from the fuel pump relay?
12 volts.
Where is the fuel pump relay and what is the voltage at the pump on a 1987 B2600 with carburetor?
i think its underneath the engine
Will the fuel pump still work properly with the fuse removed?
No, it will not run at all as there will be no voltage applied to the pump.
