LIFT UPS is an OFF LINE UPS which has 3 main parts namely – Charger, Inverter and Batteries. As majority of Elevators use three phase power supply, the UPS also is three phase input and three phase output type. It means, the LIFT UPS takes three phase supply and feeds to Elevator simultaneously charging the batteries. In case of a power cut, the inverter turns on battery mode and generates three phase output to feed the load. This transition takes place within a time period of 15-20 seconds depending upon the configuration of the variable frequency drive (VFD V3F) used by the elevator. (Renutron has recently developed a system such that the near zero transfer from utility to battery mode is possible for any type of VF drive) When the mains supply or utility gets restored, the elevator is transferred automatically to mains supply and battery charging starts. Depending upon the size and number of batteries the backup time can be extended from 2-3 Hours up to 8 Hours too.

While designing the Lift back up power solution various parameters such as normal power cut duration, type of Lift ( with or without VFD ), lift motor capacity, if the building is residential or commercial, number of floors & number of flats, usage of Lift and any other load such as staircase parking garden lights, water or fire-fighting pump CCTV or any other similar needs to be backed up are considered.

Renutron was one of the first few UPS manufacturing companies, which started exploring the idea of using Three phase UPS / Static Inverter for Elevator applications. Today we have over 3500 successful UPS installations across India, for almost 150 different top brands of elevators. Undoubtedly we are the most experienced and leading company in this elevator back up / Lift UPS segment.

RENUTRON make ON-LINE UPS are designed at our in house R&D Dept. for indigenous power conditions. It is especially suited for industrial and rural power conditions where heavy power fluctuations and prolonged power cuts are observed. Its wide input range prevents batteries from getting discharged frequently also makes it compatible for DG sets. It has a heavy duty charger for recharging the batteries in different modes (float, normal and boost). The user has option to connect the batteries of different capacities for different back up time requirements as desired.   RENUTRON uses latest technology dsPIC controllers. RENUTRON UPS are more safe, as it uses built in isolation transformers, unlike some of the MNC UPS. As a result it provides additional buffer by preventing leakage currents from utility/ distribution to reach the delicate load connected to UPS output. It also does NOT require any power conditioning device such as input cut out or isolation transformer / stabilizer or an additional battery charger.   All UPS systems manufactured by RENUTRON has minimum field proven design life of 20+ years with 98% uptime for 24x7x365 mission critical applications.   ON-LINE UPS is worldwide the most preferred choice, when it comes to protect any delicate electronic and electrical equipment or DATA, from power fluctuations and outages. It consists of three major components: Charger, Batteries and inverter. On line UPS is also known as double conversion UPS i.e. it takes raw utility AC power, converts it into clean DC power and further back into AC to feed the load un-interrupted & clean power. It uses battery as a standby source of power. In case of mains supply failure or fluctuations beyond some specified limits, the UPS switches over automatically onto BATTERY mode. As the utility supply restores normal, the UPS switches back to mains mode and starts recharging the batteries. Established in 1995, RENUTRON today has experience of 22 years in the field of power conditioning. Its time tested QMS results into consistent quality products, the ISO 9001 certification is since year 2000. Along with reliable, quality products, RENUTRON also provides prompt and efficient on-site service supports during and post warranty.
