How energy efficient is DOT?

So I have been using DOT for a year now and always have been keeping it on standby even the switch is next to it, sometimes I come home only to find the DOT has tripped due to voltage fluctuations (Even though it shouldn’t have because it has a PRCD)(Portable Residual Current Device) Its a device which works as the system detects the flow of current and detects a leak of more than 30ma through an unwanted path.

So Coming back to the question, all modern electronics or appliances come with an energy rating, (Not an energy star rating) Which defines how efficient the device is while working and while on standby.

Some of us might remember the early installers who came to install DOT might have mentioned to us that DOT consumes around 3.5 Amps on working and has very little stray residue on standby. This means 3.5 x 220 volts it’s 770 watts of power. but the output of Dot is 58.8v on 12a which means 705.6 watts. that means it has a loss of almost 65 watts in power conversion. While 65 watts might not sound huge but today’s 32" led TV work on 65 watts.

Maybe Ather can design the power factor correction and remove the stray components from the board of DOT and upgrade to more efficient latest microcontrollers.
