31 maj 2022 · Synopsis: Build a powerful 1200W motor driver with Mark Harris in this open source H-Bridge project. Learn about H-Bridges, and designing high current circuit boards with this 100 amp demonstration board.
This Verified Design shows a low cost circuit to measure currents with very high common mode of up to 400V using an INA138. A DDZ12CSF-7 Zener Diode and STR2550 Transistor were used to create a simple floating power supply and biasing the INA138 directly from the high voltage source. The 400V in this design is an example. With different components
The principle aspect of this design uses a unidirectional circuit to monitor a system with Vcm = 400V by floating the supplies of the device across a Zener diode from the supply bus (Vcm). This cookbook is based on the High Voltage 12V – 400V DC Current Sense Reference Design. Rshunt 50m.
27 wrz 2020 · If you have 12V DC from your converter, you should be good, as long as it can provide sufficient current to power the coil. The coil of the 2449-A3M1CSQ12VDC2-ND requires about 150mA at 12V DC, so be sure the converter can provide that much current.
28 kwi 2017 · The simplest answer is two Schottky diodes. Put a diode in series with each source. The current will come from the source putting out the highest voltage. Here, I've just put generic high-current Schottky diodes in the schematic, but you can use cheaper ones depending on your requirements. simulate this circuit – Schematic created using ...
How to build Regulated 12 Volt Supply. Notes: This circuit above uses a 13 volt zener diode, D2 which provides the voltage regulation. Aprroximately 0.7 Volts are dropped across the transistors b-e junction, leaving a higher current 12.3 Volt output supply. This circuit can supply loads of up to 500 mA.
