Prostar standby home ups power backup 500VA – 3000VA inbuilt battery is the simplest and least expensive uninterruptible power supply system. Actually, some don’t even consider it as a UPS, because of the presence of a momentary break during transfer or switching. Due to that, an offline UPS is sometimes described as a standby power supply (SPS). Nonetheless, the design employed by the standby UPS is the one commonly available at retail stores for protection of desktop and other small computers.
Off line UPS passes the AC Mains Supply directly to the output load if the AC Mains Supply is present.Only in the case of power failure, it switches to inverter within few miliseconds to give power to load until mains supply returns.
When mains supply is present, Prostar standby home ups power backup 500VA – 3000VA is supplied via a built-in EMI/RFI filter which provides the load with protection from spikes and transients by clamping peak voltage to pre-defined levels.
When the mains supply fails or fluctuates outside of the UPS’s operating window, a relay connects the load to the inverter output (resulting in a 4-8ms transfer time). In normal operation, with mains supply present, both output voltage and frequency will track the input voltage and frequency respectively.
-1- Intelligent CPU control.
-2- Low power consumptions.
-3- High voltage protection.
-4- Automatic voltage regulation.
-5- Cold start capability allows the load to power on just on battery.
-6- Auto restart when mains is recovering.
-7- Low battery warning.
-8- Off-mode battery charging function.
-9- Compatible with low power loads e.g. wifi router, DSLmodem.
-10- Intelligent charging system for long battery life.
-11- Automatic Voltage Regulation (AVR) corrects incoming voltage.
-12- Built-in type and external battery models with different back-up times.
-13- Optional USB communication port and RS232/RJ-11/RJ-45 interface.
Built-in CC charger keep battery charged in Constant Current while charging. Power solution 2000VA UPS UPS power solution.
Built-in CV charger keep battery charged in Constant Voltage after fully charged to ensure battery power.
Offering completed power protection to guard the connected devices against from surge, over-voltage and under-voltage damage.
Supplies power long enough for equipment to properly shut down when utility power fails. Helps prevent loss of data and minimizes the component stress caused by a hard shutdown.
Diverts excess voltage away from sensitive electronic equipment during an AC power surge or power spike to prevent damage.
Uses pulse wave modulation to generate a stepped, approximated sine wave to supply cost-effective battery backup power for equipment that does not require sine wave output.
