Lento 650VA DSP Sine wave Home Inverter 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 600VA Home Inverter 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.
