Lento Industries Pvt. Ltd products

Lento’s advanced line of affordable solar chargers are compact, ruggedized for operation in extreme weather conditions and are designed for durability. This line of solar chargers are designed to work in standalone solar power systems where they form an essential link between the SPV modules and the battery. Our solar chargers play a crucial role in maintaining battery health, better efficiency and improved performance.

Lento solar panels are manufactured under controlled conditions with rigorous tests to ensure performance and rated performance over rated life. We use high efficiency polycrystalline silicon cells and the latest in bonding techniques to interconnect cells followed by vacuum sealing and affixing to frames resulting in compact construction, space savings with corresponding higher output of power. The result is a panel that withstands climatic conditions and performs efficiently over its rated life of 25 years with only a drop of 5 to 10%.

Lento’s portable, high efficiency solar lantern is the outcome of intensive research and development. The solar lantern conforms to and exceeds MNRE specifications. It has been built to be affordable but it is rugged, highly durable, requires minimum maintenance and has an extremely long life span.

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 LED bulbs and tube lights stand out in terms of design, high lumen output, pleasing color rendering quality and long life. We manufacture LED bulbs using SMD based LED lamps affixed to heatsinks for heat dissipation. This keeps LED cool and extends their useful life. Our LED bulbs also feature vents for easy air flow. Tied to perfectly designed and matching electronic controller circuitry, Lento LED bulbs give rated lumen output for the rated life and prove to be best value for money. Lento LED tubelights use the same SMD LEDs but arranged in a strip fashion with integrated controller circuitry and heat sinking but in a package similar to T8/T5 dimensions to provide a direct fit into existing fluorescent lamp fixtures.

Lento has engineering and design capabilities as well as wealth of knowledge when it comes to providing power and lighting solutions. Lento can design and deliver a variety of customized lighting solutions for specific applications.

High frequency technology is inherently more efficient and, in some cases, works better than the standard low frequency technology. Lento offers a range of high frequency series UPS specifically for use in such environments that requires high efficiency with high reliability and power factor controlled.

In industrial environments the power supply is quite noise due to a variety of loads. Operating critical, expensive and sensitive electronic devices in such environments put them at risk. Harmonics, voltage fluctuations, voltage peaks, mains failure, abrupt low voltages and blackouts are common in such environments. Lightning and electrostatic discharges are another threat to sensitive data equipped with CMOS chips. The solution is to use Lento DSP sine wave online UPS. Lento online UPS DSP power supplies incorporate inverters that draw power from the mains and deliver highly stabilized, noise-free supply for sensitive electronic equipments.

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.
