Lento Industries Pvt. Ltd products

Lento pioneered pure Sine wave technology in its inverters, UPS and power supplies. Our Sine wave inverters output stable frequency and voltage, mimicking mains power supply, making it perfectly suitable to power expensive equipments, especially inductive loads that do not work well on square waves.

Most appliances like CFL, fans, motor based equipments like air conditioners and pump sets are designed to work on 50 Hz sine wave. Running such equipments on unregulated quasi sine wave-square wave based inverters poses a risk as regards performance and durability. Lento DSP sine wave Static UPS and inverters are designed to provide stable 50 Hz sine wave irrespective of load and battery voltage, making them the most suitable for inductive, capacitive and non-resistive loads. Importantly, our inverters and UPS are designed to deliver instantaneous high current during start up, especially in case of air conditioners and refrigerators, with safety cut out when battery voltage goes lower than a specified point to avoid brownouts and burning of motors.

Lento DSP sine wave online UPS feature a wealth of advance features. Designed for use with expensive critical electronics instrumentation, these UPS systems have a host of safety controls to ensure your devices are always protected. Lento DSP online UPS performs very well in case of mains failure, sensing of voltage fluctuations and automatic switchover, lighting guard, electrostatic protection, overvoltage and overload protection, short circuit protection and low battery protection. Lento DSP UPS are configured to be always active when power fails. At the same time, the batteries are kept constantly charged through a monitoring circuit to ensure their longevity. DSP sine wave online UPS are preferred especially when they are Lento with guaranteed frequency and voltage control along with inbuilt protection features.

Monitoring of battery voltage, optimum charging of battery, state of battery charge monitor, low voltage and overload cut out.

Lento offers next generation smart MPPT based solar chargers for maximum efficiency and highest performance required in demanding situation. MPPT stands for maximum power point tracking and Lento’s smart MPPT solar chargers play a crucial, central role in stand alone and hybrid solar power installation. MPPT increases energy transfer efficiency by as much as 30% by calculating maximum voltage available from the SPV modules at which maximum power is available for charging and sets the charging current accordingly. Output from SPV modules can vary considerably according to changing weather conditions and incorporation of MPPT means the charging conditions are always optimized by covering extra voltage to amperes and thus speeding up the charging process. Lento uses high grade components to assure best performance and extended life of the unit.

Solar Hybrid Systems (PCU) are ideal in case of higher loads. The hybrid solar system features a bank of solar photovoltaic modules tied to a bank of batteries with a controlling interface. The controlling interface is the critical component here.

Lento solar street lights are the future of lighting up roads with ultra high efficiency, clean-green source of energy. Lento offers both CFL based and high lumen high efficiency LED based solar street lights. Lento solar street lights find applications for lighting roads inside villages, towns and cities, inside private domestic and commercial compounds, in hospitals and in remote areas where grid power is just not available. Lento solar street lights are designed with modular construction, easy to fit by anyone with minimum of training and low maintenance due to use of high quality components and rigid manufacturing processes.

Lento sealed maintenance-free batteries are the perfect solution when you want batteries that last for a long time and perform consistently throughout their life.

An automotive battery is a rechargeable battery that supplies electrical current to a motor vehicle. Its main purpose is to feed the starter, which starts the engine. Once the engine is running, power for the car’s electrical systems is supplied by the alternator. Typically, starting discharges less than three per cent of the battery capacity. SLI (Starting, Lighting and Ignition) batteries are designed to release a high burst of current and then be quickly recharged. They are not designed for deep discharge, and a full discharge can reduce the battery’s lifespan.
