The most frequently being used in Pakistan. It can charge batteries upto 165Ah. Just like the other it has same other features but has more backup time and output power as it handle large battery. Its true power is measured as 650W. It is the best choice for normal families. Its output just like other also matches our standard which is 220v-230v AC 50Hz.

The model 1kWs requires single battery 12v upto 200Ah, in order to get more power you can switch to the sub model 1kWsD that requires double battery. So, we can say that it operates at 24v coz battery needs to be connected in series. This kind of arrangement allowed to have more long backup.

Is it good buying this because market has a lot of more models, provide any good reason to buy it ?
First of all there is very less power consumption you save a lot of energy as compared to cheap Chinese inverter. The other locally made are real rough they don't deliver true power as they mention.

Its main part the transformer can last upto 10 years.

Phantom Powered Preamp

This is our project we did last year its a "Phantom Power Preamp with Balanced Input and Unbalanced Input". Below you can see the picture:
It is single channel balanced microphone pre-amplifier. Specially made for the condenser microphones. It can power all kinds of condenser microphones and amplify their low singals amplitudes and gives you analog output through the RCA Connectors. Above two RCA connectors are for the output while the other two below the line out are for the "Line Input". There is a separate volume control knob for the line input. The pre-amp volume can be adjusted with the other knob. 

It gives highest quality output for professional level recordings. Provides better response for your microphone. Gives 35v for the phantom power.
No additional hardware is required to power it. There is another unbalanced input for the instruments and some dynamic microphones through the TSR 6.5mm female jack. There is also the headphone output which is through 3.5mm female jack which can be used to either monitor the incoming audio from your microphone or line input or you can take line-out to other mixer.

Noiseless and high quality (Tube Preamp Equivalent) performance.  Its circuitry is complex and perfectly engineered for the high quality and noiseless performance. It is based on Opamps and these opamps are highly expensive. 

Requires 220v power cord cable, No adapter is required.

Project Code : STP-PPA-071
