Uninterruptible Power Supply (UPS) Circuit Diagram

Uninterruptible Power Supply (UPS) Circuit Diagram 

The circuit drawn pertains to some regular industrial UPS (Uninterruptible Power Supply), which exhibits how the batteries get control throughout an outage in electrical provide or variation over and above the normal limits in the voltage line, without disruption around the operation offering a continual regulated output (5 Volts by LM7805) and an unregulated provide (12 Volts).



The input to the primary winding from the transformer (TR1) is 240V. The secondary winding may be raised up to 15 Volts in the event the value is at least 12 Volts operating two amp. The fuse (FS1) acts being a mini circuit breaker for protection in opposition to brief circuits, or perhaps a defective battery cell actually. The presence of electrical energy will trigger the LED 1 to light. The light of LED will set off upon power outage and the UPS battery will get above

The circuit was developed to offer you additional flexible pattern wherein it may be custom-made by working with various regulators and batteries to generate regulated and unregulated voltages. Utilizing two twelve Volt batteries in series as well as a constructive input 7815 regulator, can control a 15V supply.


Industrial UPS are generally categorized as:
Standby – battery backup and surge safety
Line Interactive – variable-voltage transformer and regulates the input AC voltage
On the net – materials all or at least a part from the output power
