Lift Inverter/ ERD (50-200KVA)

Works Best with Lithium Ion and LiFePO4 Batteries

Su-vastika lifts inverter/lift UPS/ERD is compatible with all types of batteries viz Lead-acid and Lithium Ion batteries. Lithium-ion/LiFePO4 batteries are compact and have three times higher efficiency in handling Lifts’ mechanical load than Lead acid batteries. Since the discharge current is very high in the Lift Inverter/Lift UPS/ERD, the SMF Lead Acid or tubular batteries have a C20 rating, so the discharge current is too high for them to take. Since a Lithium battery comes with a C1 rating, this is the best battery for the Lift Inverter application as the life it will get is around 7 to 10 years compared to a Lead Acid battery which will last a maximum of 2 years.

The price of the Lift inverter or the price of lift UPS will be cheaper in the case of lead Acid battery, but in the long run, the Price Of Lift inverter or the price of Lift UPS will be more affordable with the Lithium battery pack. Also, the space taken by the Lead acid battery bank is another important parameter to consider, as the space in the lift room is very limited to install the Lift Inverter with such a heavy Lead Acid Battery Bank.

ERD Brings Tailor-made Solution

• ERD can be designed for small to big lifts up to 500 KVA load
• ERD can run on lead-Acid as well as lithium batteries
• Works on Bypass mode hence protects battery from continuous charging as in case of Online UPS
• Make to order for Regenerative lifts
• Does not require any air conditioner.

ERD Is Solar Enabled

ERD is a green & clean technology which can make it solar enabled system by adding a charge controller and solar panels, which can charge the ERD power bank through solar energy. We have developed a technology where solar can be added at any stage.

The extra electronic board of charge controller is inserted and that talks to the controller board of the ERD and these two work in a synchronized manner. As when solar is available the battery charging is happening through solar or if solar is less than the charging is happening through the sharing of solar and grid both. But the priority is always through the solar. When the batteries are charged and solar is available then the system switch off the mains and works on the solar and battery power to save the power bill completely. Since the battery is charged through the solar the battery life increases to 20 to 40 percent. Also, in this case, the generator may not be required at all because solar power takes care of a long backup time as well.

ERD Display / Electronic Control Unit

ECU as the name is Electronic Control Unit which is installed inside the lift which act as a Display and gives indication to the people traveling in the lift that lift is working on the Mains power or on the ERD power. Since there is no feeling comes to the passenger travelling in the lift of power outage so it’s important to give the idea to the passenger that lift is working on the emergency backup. So, this ECU has the announcement facility as well so there is a memory card inside the ECU which can be used as a recorder to record the announcement messages in different languages and that can be programmed on the site itself. In case of battery getting low or completely discharged it give the indication along with the announcements to the passenger travelling in the lift. It will save the space as well as cost and maintenance.

Central ERD System

Su-vastika has designed 10 KVA to 500 KVA ERD system which can run 4 to 20 lifts together of different capacities and can be placed in a ground position in the Area which can save the costing, space and maintenance cost. This central unit can be used as a back- up for common lights of the building as well. Since there are no switching time so common areas lights will also keep functioning without any flicker along with the continuous operation of lifts in case of power failure.

We have already completed a project of Chintels Paradiso where we have operated 18 lifts with one central ERD system. We have specially designed two ERD’s of 150 KVA & 200 KVA to run the 18 lifts of the capacity of 11.5 KV along with the 20 motors which are working in the complex situation for various other applications. These ERD’s have no switching time so the motors & other load connected to it has no inrush current requirements & every load is working without any switching time so people can’t feel any break in services.

Customised ERD for Regenerative Load

For conventional lifts, the power generated by the traction machine is dissipated as heat in the building, which wastes energy and creates unwanted heat in the machine rooms.

Lifts with a regenerative function obtain power from the electrical supply network; when it travels downwards with a heavy load or upwards with a light load, the traction machine will act as a power generator. These Regenerative Lifts, the new technology is, used to feedback this Regenerative energy coming from the lifts to the grid, and the grid reutilise this energy. Compared to conventional lifts, regenerative lifts are 20% to 30% more energy efficient.

Su-vastika also manufactures premium regenerative lift backup Lift Inverters/UPS/ERD. We at Su-vastika are continuously improving the technology so that we can improve our technology as per the lift manufacturers’ expectations.

Su-Vastika Bluetooth/WiFi Monitoring App

Su-vastika has developed Bluetooth and WiFi app for all its Inverters/UPS/Home UPS/ Solar Hybrid PCU/ERD/ESS that helps to monitor and control UPS through Mobile app or direct PC and loaded with the patented software.

This feature offers many advantages over regular Inverters/UPS.

• Ease of installation: Bluetooth and WiFi-enabled inverters can be installed without need for any extraordinary changes as Su-vastika all UPS have the USB port at the back to have Bluetooth/Wifi compatibility
• Remote monitoring: With Bluetooth and WiFi, you can monitor your inverter from anywhere worldwide, as long as you have an internet connection. This is ideal for homeowners who want to keep an eye on the power situation at home or office while they’re away.
• Real-time data: Bluetooth and WiFi-enabled inverters can provide real-time data on your Inverter/UPS system performance. This data can be used to optimise your system’s performance and troubleshoot any problems.
• Digital Warranty: The Digital Warranty gives you peace of mind as you don’t need to keep any documents, and it works inside the microprocessor. The warranty works with the usage of the Inverter/UPS and not from the day you purchase the product..
• Voltage and frequency: In case of low or high Voltage, one can have the data recorded for the high and low voltages.
• Shows charging percentage of the battery
