Simple Low Voltage Cut OFF Circuit

Last Updated on January 10, 2018 by Admin 4 Comments

LOW VOLTAGE CUT-OUT
This particular circuit will probably identify once the voltage of a 12v battery extends to a minimal level. This is certainly to counteract deep-discharge or possibly in order to avoid an automobile battery getting discharged into a stage just where it will fail to start up a motor vehicle. This circuit differs from the others to everything formerly offered. It includes HYSTERESIS. Hysteresis is actually a characteristic in which the lower and upper detection-points are usually segregated with a distance.
Commonly, this low voltage cut off circuit will probably disconnect the relay once the voltage is 10v then when the load is taken out. The battery voltage may climb somewhat through less than 50mV and change the circuit ON yet again. This can be referred to as "Searching." The off/on delay continues to be decreased by including our 100u. But to avoid this absolutely from taking place, a 10R to 47R is scheduled in the emitter terminal. The circuit may shut off at 10v but actually will never turn back ON until eventually 10.6v each time a 33R is in the emitter.
The value of this particular resistor as well as the turn-on and turn-off voltages will in addition rely on the resistance of the relay coil.

कम वोल्टेज कट आउट
एक 12V बैटरी की वोल्टेज एक न्यूनतम स्तर तक फैली हुई है एक बार इस विशेष सर्किट शायद पहचान करेगा। यह यह एक मोटर वाहन को शुरू करने के लिए असफल हो जायेगी जहां सिर्फ एक चरण में छुट्टी दे दी हो रही एक ऑटोमोबाइल बैटरी से बचने के लिए संभवतः गहरे निर्वहन या प्रतिक्रिया करने के लिए निश्चित रूप से है। इस सर्किट में पूर्व में की पेशकश की है सब कुछ करने के लिए दूसरों से अलग है। यह हिस्टैरिसीस भी शामिल है। हिस्टैरिसीस वास्तव में निचले और ऊपरी पता लगाने अंक आमतौर पर एक दूरी से अलग कर रहे हैं, जिसमें एक विशेषता है।
लोड बाहर ले जाया जाता है जब वोल्टेज तो 10V है एक बार आमतौर पर, यह कम वोल्टेज काट सर्किट शायद रिले काटना होगा। बैटरी वोल्टेज 50mV से भी कम समय के माध्यम से कुछ हद तक चढ़ाई और एक बार फिर पर सर्किट बदल सकते हैं। इस रूप में भेजा जा सकता है "सर्च कर रहे हैं।" देरी पर बंद / हमारे 100U शामिल करके कम किया जाना जारी है। लेकिन पूरी तरह से जगह ले जाने से बचने के लिए, 47R के लिए एक 10R emitter टर्मिनल में निर्धारित है। सर्किट 10v में बंद हो सकती है, लेकिन अंत में एक 33R emitter में है हर बार 10.6v जब तक वास्तव में पर वापस बारी कभी नहीं होगा।
यह विशेष रूप से संघर्ष के मूल्य के रूप में अच्छी तरह से मोड़ पर और बारी-बंद voltages के अलावा रिले का तार के प्रतिरोध पर निर्भर करेगा।

About Admin

Hey friends, Thanks a bunch for stopping by this site! I am an engineer with a Bachelor of Engineering in Electronics and Telecommunication. One of my passions is gathering information from all sorts of electronics books and tutorials. I then take that information and compile it into a language that is super easy to understand. My goal is to make those complex electronics circuit concepts and technical terms much more accessible for all the new and budding electronics engineers out there. I can also design customized circuit diagrams as required by the users.
If you have any questions related to this field, please do not hesitate to drop a comment! I am always here and ready to help you out with any queries you might have. I cannot wait to hear from you!

Can this circuit handle up to 260 amp 24 volt charging current, and 3,000 watt load?

Yes, it can, if you select an appropriate relay with contact rating of over 300 amps.
