Active Redundancy UPS Manufacturer

ZNER DSP based Compact Domestic Sinewave UPS-cum-Inverter with Charger ZNER Microcontroller based sine wave UPS/Inverter with charger Introduction ZNER has developed a new micro-controller based digital sine wave inverter using DSP (Digital Signal Processor) with full bridge configuration topology MOSFET switches.: Isolated sensing of Mains: This will ensure that even if Phase-Neutral connection is reversed at the input side there will not be any electric shock on the PCB or battery. Cycle-Cycle current Limiting: This is a enhanced protection method for the short circuit / heavy load condition. Low cost driver: The costly driver with TLP250 is replaced with discrete components on the PCB LED/7-segment/LCD display: The PCB is designed with provision for LED, 7-segment display or LCD display. This inverter is best suited for manufacturing for domestic applications as it is simple and easy. It consists only few components which are easily available, have only 3 smd components and with a single sided pcb. There are no windings which can possibly cause any error such as DC-CT or EE-16 transformers. Mounting of heatsink along with mosfets and soldering few components will complete this board. It consists of a LCD which will display all the parameters of the system and indicates any error during the functioning of the inverter. A low cost 16 character single line LCD will be of scrolling type, showing the status of the inverter such as batt voltage, mains voltage, inverter output voltage, inverter standby on/off, charger on/off, mains/ solar charging and many more. It is very simple to handle and very easy to set the values in the menu driven set-up mode. This inverter is a very robust design which will not fail in any extreme conditions. 1. If 440V is applied to the AC input, it will not fail. It will indicate high voltage cut-off and restart when voltage is normal. 2. If AC mains is given to the inverter output, it will not fail. It will indicate phase input output reverse and continue to work after it is rectified. 3. It has fold-back current limiting for short circuit and heavy loads. At short circuit or heavy loads, current limiting action will take place instead of tripping which will lead to more reliability. Features  LCD display for indicating various status of the system like inverter voltage, mains voltage, battery voltage, % of load, overload/short circuit status, battery low status, charger status etc.  LCD based Menu driven setup of various parameters like battery full charge voltage, battery low voltage, load condition, Inverter output voltage, charging current etc.  Protections against: Overload, short circuit, battery deep discharge, battery over charge, mains over voltage, reverse connection of phase in – phase out, reverse connection of phase and neutral of mains input. In all these error conditions will be shown in the LCD display.  Priority solar charging facility: When solar charger is connected mains charger will be in stand-by and priority will be for solar charger.  Delayed inverter cutoff for conditions like battery low, overload, short circuit etc. The system will automatically restart from cutoff after a few second buzzer beeps. The system will go to permanent cut-off if the error condition exists even after 4 restart
