· It is a inverter which can change DC power to AC 220V/50Hz with advanced switching technology. The DC power is often from battery 12V, 24V, 48V ... There are two main product kinds with many capacities required by using:
- Stepped Sine Wave(modified sine wave): Modified sine wave inverter is small and cheap. It is usefull for devices as computers, compact lamp, TV, DVD, CD, MP3 ... However, it is not used for with these devices as the fan, motor ...
- True Sine Wave(Pure sine wave): The output wave form is completely power grid. This kind of product allows fine with all electrical devices. However, Its price is higher than stepped sine wave’s.
· Using for:
- On the ship, car, boat and others transportation.
- In rural areas, islands or where no electrical grid, but there has been a source chiêu from sources of natural energy (sun, wind, water ...).
- In the rural countries, iland or some places where hasn’t got grid but there is DC power from nature(solar/ wind power, hydro-elestricity…)
- In special requirements such as information system, control, the moderation center of the national power and ect.
· Particularly, AST receives to produce 3 phase DC-AC Inverter as required by customers
· Remarkable feature of the AST inverter:
- Integrated full feature flexibility and strict protection (overload, over temperature, short circuits ...).
- Automatic stop working when battery is empty(to protect the battery).
- High Performance.
- Booting (peak capacity) high.
- Stable Frequency 50Hz (± 0.5%).
- High stability of the high voltage 220V (± 7%).
- Show the full status of work on such as Batterry voltage, the using load, error ...
- Beautiful streamlined design and functional diversity. Especially, AST can design, produce all the needs of customers.
- The components are imported and selected carefully to help the product of AST performance, reliability and long life.
- Production line with modern standards of quality management ISO 9001:2000
- Ability to work in severe environment.
