When people only have dc power, a single-phase sine wave frequency inverter power supply can be used to convert Direct Current (DC) into Alternating Current (AC) in order to power up some ac device. Our plan is to create a device that allows us to change the frequency and output voltage. So we use an inverter circuit to generate alternating current and a microcontroller to change its frequency. Eventually, this circuit will be able to generate 40-50Hz sin waves, which can be used to replace alternating current power in some situations.

Lento DSP Sine Wave Static UPS is developed with advanced technology to provide Pure Sine Wave output. Lento Inverters / UPS deliver best of the power supplies if compared with ordinary UPS and inverter systems. UPS of other brands delivers distorted output particularly on normally encountered loads like Compact Fluorescent Lamp (CFL), Tube Lights, Motors, Coolers, Computers, etc. Distorted waveform is harmful for almost all the home appliances. Lento Industries Private Limited delivers quality output in its Static UPS with reliable performance at a reasonable price.

Our Domestic Series of Inverters has become very popular among a number of customers. Our domestic inverters and UPS systems are designed for providing an even flow of power output for different home appliances. Lento Industries Private Limited is emerging as the leading manufacturer, supplier and exporter in the countries like South Africa, Tanzania, Mozambique, Uganda, Kenya, Ethiopia, Yemen, Saudi Arabia, Iraq, Iran, UAE, Senegal, Nigeria, Ghana, Nepal, Bangladesh, Vietnam etc.
