Basic Uninterruptible Power Supply Diagram

The following circuit is the basic form of the commercial Uninterruptible Power Supply (UPS), the circuit gives a constant regulated 5 Volt output and an unregulated 12 Volt supply. Within the event of electrical supply line failure the battery pack takes over, with no spikes on the regulated supply. This circuit could be modified for […]

Simple Uninterruptible Power Supply (UPS)

This schematic is simply a basic system of UPS (uninteruptible power supply). The main schematic gives a continuous regulated 5 Volt result with an not regulated 12 Volt supply. Regarding electricity line fail the battery will take control, without any surges within the regulated supply. Notices: These schematic may possibly customized for the purpose of […]

220 watts Uninterruptible Power Supply

Uninterruptible power supply provides output power to 220 watts (load current up to 1A). In the mode switch SB1 12/220 – the battery voltage is applied to a given multivibrator Q3 Q4 50 Hz, which builds up powerful keys Q1, Q6, amplified and fed to transformer T1. With the secondary winding T1 voltage of 220 […]

600 Watt Uninterruptible Power Supply

The schematic in figur is the circuit of 600W UPS. Stay powered and radio during a power failure. Output frequency – 50 Hz, Power Consumption 600 Watts, the shape of the output signal – sinusoidal, the efficiency – 98%. The device contains an auto power off at the mains, followed by automatic switch-off with the […]

Mini UPS

Here the simple Mini UPS circuit diagram. This circuit can provide an uninterrupted power supply (UPS) to operate 12V, 9V and 5V DC-powered instruments at up to 1A current. The backup battery will take up the load with no spikes or delay when the mains electrical power gets interrupted. It could possibly also be utilized […]

Basic UPS Circuit

The above diagram is a basic Uninterupted Power Supply (UPS) circuit. This is a very simple and inexpensive circuit. This circuit can be adapted/modified for other regulated and unregulated voltages by using different regulators and batteries. For a 15 Volt regulated supply, you may apply two 12V batteries connected in series (it will become 24V) […]
