YOU THINK WE MAKE
Thodukonics Invented a new technique for wireless communication via 100~250 volt ac electric line in1990 and started marketing them in the brand name of Powerfone. The main advantage of this advanced intercommunication equipment, the Powerfone, is that this intercom requires no extra wiring as it can work through electric power supply wire. And it will be working any country which is AC voltage from 90V to 250V. You can get the best performance and long range, when the Powerfones are connected on the same power distribution transformer and same phase lines. You can also plug our intercom into "DUAL Phase" 220V AC outlet for avoiding phase problem (110V region). Conclusion: Normal Telephone working via Telephone line (wire) then our intercom working via 110V or 230V electric supply line. So that not required any additional wiring.  The use of high quality components, precisely tuned electronic oscillator circuits and the advanced FM technology in our systems, enable you to get the digital clarity  and long range, in comparison with the same kind of products available in the global market. The Strict quality control in the manufacturing process ensure durability and the best operational performance of these products. Actually there are no equivalent products in the market for some of our models.
