...should be applied separately for each winding and the following output voltages should be obtained: 1st output +12VDC1 28A ; 2nd output +12VDC2 28A; 3. output +3.3VDC 32A; 4. output +5VDC 28A; 5. output -12VDC 0.53A; The fan should have +12VDC 0.85A output. Since the voltages coming out from here will be irregular, voltage outputs should be fixed by giving a voltage regulator for each output. The 5 volt output also feeds the optocoupler and triggers a circuit element that will cut the transformer's power in case of failures where no 5v output is received. Thus, when the output voltage is not received, the input voltage 220V is cut off. There is also +5VDC 2.5A Standby voltage in the circuit. This voltage depends on the motherboard. Turns off power to the power supply when th...

Hie, I am working on a project related to management in an unbalanced power distribution system. For this we need to do the Volt-Var optimization (VVO) using PSO or any suitable optimization methods based upon the defined objective functions such as power loss. The proposed algorithm should determines control variable settings such as tap positions for voltage regulators and on line tap changer (OLTC), and the number of shunt capacitors to be switched for real power loss minimization in the distribution system. VVO: Volt/VAR optimization (VVO) is a process of optimally managing voltage levels and reactive power to achieve more efficient gird operation by reducing system losses, peak demand or energy consumption or a combination of the three. During the process, voltage contr...

Build it in to test and submit. See attached document with nice table showing all conditions. But I will try to write it out for you here: - 12 volt power supply must be used to power Arduino. (Make it simple and efficient for power) - There is momentary switch (normally open), On/Off switch, Buzzer and 2 LEDs. - Depending on the condition of the switches the buzzer and LED will sound and flash. For details about the timing and conditions see the attached document. I will email you a shared link where you can build it and test in my tinkercad. Check out and setup you own account so I can share a link if this project is awarded to you. Thank You! Jim

We supply alcohol interlocks to governing body contracts across Australia and require diagnostic plugs to test our installed wiring harnesses in the vehicle (150 in total). The device can be designed here and we can arrange for it to be made overseas or can be made local if price is competitive. The harness uses a parallel printer cable which plugs into the coresponding socket on our device. the goal is to have a small diagnostic box with LED lamps to indicate power connection. Ideally the diagnostic connector could be placed inline with our device and cable and have the additional function of only being used to identify faults within the wiring or cable.

I have a system with -48vdc batteries (max -60vdc) , where the positive voltage is grounded. The following link has a similar system: My problem is how to bring a negative voltage to the arduino Uno because we know that adruino only measures positive. From the equipment I have: - Adruino Uno R3 - LCD Keypad Shield Kit -Data loger shield arduino Uno - LM4040DIZ-4.1 Voltage Reference The Arduino Uno power supply is a Battery bank. The idea is to connect from the system -48vdc minus and plus pole to the arduino Uno and to measure the voltage for 30 minutes and every minute to record the voltage value on the SD card.
