Heritage Model - 500 VA
True Sinewave inverter card is an efficient and reliable system, which outputs a Pure Sinewave based on high frequency PWM,. The output has low distortion giving longer life to appliances and lower heat loss leading to an overall efficiency. The DSP based systems ensures lower component failure, hence higher reliability. The system is highly fault tolerant and no component failure has been observed under output short circuit, overload and output wrongly connected to phase. The SMPS Technology based Battery charging system ensures faster charging and safe charging. Because of the low ripple currents longer battery life is projected. Batteries are charged from an input mains voltage as low as 120v.
Key Features:
- Phase synchronous ultra fast transfer.
- Settable charging current, output voltage and battery boost voltage.
- Commonly available components.
- Affordable and appropriate technology.
- Better life of user equipment.
- Saving on technical manpower and costly equipment.
Charging control: This has a advanced charging system that employs the best of two worlds. A bulk charge state and a finishing charge state with tapered current control for low gassing. Battery will be charged under constant current. After the constant current phase is over than the charger will charge the battery till the set END - VOLTAGE with as a tapering current, at end of charge, the battery will float at 2.18v/cell. If mains supply is below 140vac charging current is limited to 5 amps for 500VA (this is to protect the transformer).
