I'm working on a mining application using a 50 HP AC motor (Baldor ECR9504T) that will be powered by a 116 kW 460V generator.
The generator can source up to 145 amps. The full load amps of the motor is 61 amps, but the starting current is listed at 394 amps. I will be using a VFD in PWM mode...
I have a 10-layer PCB design with a controlled impedance of 50 Ohm +/- 10% for all four internal signal planes. On one of the signal planes, I have a signal that carries a 25 MHz clock signal for an LCD. This signal appears to contain several other frequencies and is far from the intended square...
I am working on a project with a Freescale i.MX processor and mating power management IC (PMIC) using Linux as the OS. The PMIC provides several peripheral features to the i.MX including a 4-wire resistive controller which currently works fine. The issue I have come across is that the 4-wire...
Hello-
I need help selecting a SMPS to power a single known component. The power profile expected is attached.
Requirements:
-10 VDC to 30 VDC input
-5 VDC @ 2A output
-Vripple less than 40mVpp
-Voltage droop for "Function 1" in the attachment cannot be greater than 0.2 Volts
-Noise should be...
I'm using a "12V" lead acid battery to power a circuit of mine. When the battery is not connected to the circuit, the voltage I'm getting on a multimeter is about 11.7V. When the circuit is active and powered by the battery, it reads 10.8V.
Why is the battery losing almost a volt in potential...
I am working on developing a system including a RS485 network. All microcontroller-based devices will be powered by a 24VDC lead acid battery system. Each system will contain a RS485 driver powered by an a 5V DC-DC buck converter. The device in question will be added to the end of a network, so...
