Lift Inverter Manufacturer & Supplier in Pune

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 e-ARD – Emergency Auto Rescue Device

Normally if the DG set runs out of fuel the running lift may come to a standstill anywhere during the travel and the passengers inside the lift get locked inside the lift car till the time someone in the society performs the tedious manual rescue operation. This is especially dangerous for children, females and age old passengers or heart patients travelling inside the lift car.

e-ARD is a device which not only updates the passenger inside the car that the lift is provided with a back-up but also if the lift is on mains or battery mode , how long the battery back-up will last and also prevents persons using lift to get trapped inside the lift in case if the battery gets exhausted. The device fitted in the lift car, has digital display and voice messaging facility too.

SMS Alerts

For township projects with multiple lifts having centralised back up, Renutron has yet another innovative solution. GSM Modem fitted inside the UPS, sends on-line SMS updates of Lift UPS to cell phones of concerned persons of each wing such as if the lift is running on battery mode, the cause of the status such as power cut, high low mains voltages single phasing or phase reversal etc. The nearest electricity sub-station number or toll free number of utility supply provider, next UPS preventive date or warranty expiry updates etc. Simultaneously the Modem also communicates some important parameters to Renutron Service In-charge and also logs service calls if any. In some cases the DATA from GSM modem enables us to prevent probable service breakdown that may occur by timely corrective action from our customer care team.
