It’s an emergency lift operating system, which suits to use for building lifts in the event of power failure. It can give backup up to 6-8 hrs. It’s economical than diesel generator in running cost of fuel as well as lift inverters are totally reliable and highly durable.
The use of advanced technologies and superior engineering in its construction makes it ideal for operation in all weather conditions. These lift on inverters are available in models from 6 KVA to 100 KVA (Three Phase).
This inverter works in the way as below
DC input is converted to AC (actually chopped DC) and presented to a transformer. Turns on the transformer provide an AC input to an output rectifying bridge then filtered and regulated. Usually the chopped DC is at a relatively high frequency so that the transformer can be small. Many different schemes are used to regulate the output. In this inverter Pulse width modulation (PWM) scheme is used.
