We modestly claim to be up there with the best, offering world class products and technologies as the outcome of our superior design capabilities 4) Renewable Enaray Management OUR INCLINATION TOWARDS GREEN TECHNOLOGIES ‘Square Wave: Very old style inverter. Ok for Bulb Loads. Not good for other appliances like Tube Lights, Fans, coolers and motors etc. + Quasi Sine Wave: In basic it is square wave inverter, but at low load conditions the circuit in this type of inverters cuts some part of the square wave, Good for Bulbs, Not good for other appliances like Tube light, LED Light, Fans, coolers and and motors ete. ‘+ Micro Controller Based Pure Sine Wave: Inverters are not pure sine wave a they claim itis. It gives low battery backup and itis very costly. Also these inverters create a very irritating high frequency noise which is very much disturbing. + DSP Based Pure Sine Wave : This is the world's latest technology Inverter manufactured by Lento. This inverter is havingaall the advantages of Sign wave Inverter with backup time equal to square wave inverters. It creates no sound in load and in inverter. This gives exact replica of AC mains which is best suited forall kind of electrical appliances as all appliances are design to operate on this. This increases the appliances life span in terms of operation life. ur units are flexible, modular and scalable allowing remote deployment with minimal physics intervention due toa high degree of electronic automated monitoring and controlling processes. Stand alone system, hybrid, home units or industrial, grid tied we have a solution for every situation, Being reliable and manufactured using military grade ‘components, oursolar systems perform day in, for years with minimal maintenance. LED is the light of the future and Lento has developed advanced LED lighting devices in the from of LED bulbs and LED tube lights with high lumen output, excellent reliability, durability, color rendering and affordable prices. For interior lighting we have affordable energy efficient LED light and streetlights we offer next generation high lumen high watt LED arrays in the range of 3W to 150W which includes LED bulbs, Tubelights & Street Light. Our LED lighting solutions ill save the nation a huge amount of energy and reduce green house gas emissions as well as the carbon footprint. BLOC motors are more versatile, mainly because of their savy in the speed and torque department. They also come in compact packages, making them viable for a variety of compact design. Typical apps include computer hard drives, mechanical-based media players, electronic-component cooling fans, cordiess power tools, HVAC and refrigeration, industrial and manufacturing systems, and direct-drive turntables. Another advantage of a BLDC motor is that it can be made smaller and lighter than a brush type with the same power output, making the former suitable for applications where space is light Because a BLDC motor dispenses with the brushes ~ instead employing an “electronic commutator” — the motor's reliability and efficiency is improved by eliminating this source of wear and power loss. In addition, BLOC motors boast a number of other advantage over brush DC motor and induction motor, including better speed versus torque characteristic; faster dynamic response; noiseless operation; and higher speed ranges. Traditionally ferrite magnets were used to make the permanent magnets, While these magnets are more expensive, they generate greater fluxdensity, allowing the ratorto be made smaller fora given torque, The use ofthese powerful magnetsia akey reason why BLDC motors deliver higher power han a brush-type DC motor of the same size. Moreover, the ratio of torque delivered relative to the motor's size is higher, making ita good choice forapplications such as washing machines and EV's where high powers needed but compactness and lightness are critical factors. (Grey Etconey Management Manufacturing Facility Lento boasts of state of art manufacturing facilities in a modular and well organized workflow environment. We have well organized sections segregated into. Input section where components are received and batch tested; * PCB design and manufacturing section where our engineers use CSD stations to design PCBs and these are later translated to PCBs. We use only glass epoxy boards for high reliability; ‘Assembly section with pick and place equipments for SMT and SMD, and wave soldering units in a highly automated, high speed process that gives us high production capabilities with consistencies and reliabilities into the process. This is the heart of our manufacturing unit producing populated PCBs for solar systems, for inverters, UPS, SMPS and LED lights. We have opted for SMT and SMD resistors, capacitors and chips for compact form factor, fast manufacturing and high reliability as cost efficiency. * Quality check division to check sup-assembly boards, * Sheet metal unit where outer cabinets are manufactured and powder coated forlong life * Final assembly and test section where each product undergoes 24 hour burn, overload, temperature and humidity tests according to international norms before being passed for dispatch, © State Of Art Manufacturing Facility Of LED Acid Tubular And SMF VRLA Batteries 6 Renewnbe Energy Management OTTEMi NA Colao Sourcing Quality Management “Quality is our Passion & Quality is our Business” Each of our products is made up of hundreds of components, majority of them sourced from reputed vendors. Still, we have our own stringent system of rigorous checks and instruments that will detect flaws in components. Our aim is to achieve zero defect and it starts with checking parts and components at source, not at the assembled stage. Here at Lento we are of the firm belief that if be take care of quality at the source, half of the work is done and that too in an easy manner since it is easy to check components before fitting into circuit board rather than try to identify faults afterwards. Hence, ourrigorous focus on checking each component at source to ensure fail safe performance. In-House Production Quality Our in-house production quality plan is simple and fool-proof because it is detailed and without compromises. We take lot-wise samples, check for all parameters and pass only assemblies that conform to specs. Only if samples pass stringent physical, electrical, mechanical and electronic tests are the final products approved for dispatch. In-Process Quality Management Production comprises number of stages. Only those components that are approved go into process. Here too, each sub-assembly is tested for all parameters using human intervention and specialized tools and equipments developed for that purpose. Only if a sub-assembly passes the tests is it approved for onward process. if faults are detected production people receive full report and our R&D is also involved in order to detect and root out such flaws forfuture batches. Final Product Quality Management The final product, whether it is a small inverter UY! ‘ora.complex, digital, microprocessor controlled ‘ UPS or power plant, undergoes the 24 hour bourn in test only once it passes the test forall parameters.
