Read Our FAQ.
An Automatic Voltage Regulator (AVR) is a device that can accept large voltage fluctuations (150 volts to 290 volts) and supply voltage to equipment that is within acceptable voltage tolerance parameters (190 volts to 242 volts) or better. It is important to note that an AVR does not provide backup in the event of a power failure.
There are many places in this world with bad electricity power supply conditions, many people are still experiencing constant surges and sags in voltage. Voltage Fluctuation is one of the main cause to the damage of home appliances. Every appliance has a certain input voltage range, if the input voltage drops below or surges higher that this range, it caused a definitely damage in the electricity. In some cases, the appliances just stop working. The Automatic Voltage Regulator is designed to solve such problems, it is designed to have a generally wider input voltage range than normally electrical appliances, and it boost up or suppress the input low and high voltage to the acceptable range.
AVR are mainly categorized into two types:
- Relay controlled tap changing type
- Servo Motor Type
The difference between Relay type and Servo Motor Type is that the Relay type responds more quickly than the Servo motor type. However, the Servo Motor regulates the output voltage more precisely: up to 3% tolerance in precision versus the 10% tolerance in the relay type.
An inverter is essentially a device that changes direct current (DC), which is current drawn from a battery to alternating current (AC) that is similar to the current that is drawn from the utility. Some inverters have built-in battery chargers and are plugged into the utility. Other inverters have solar panel (PV) inputs, whereby the batteries of the inverter are charged by solar power. There are also hybrid inverters that do both the above. Alpha Power supplies inverters that cater for all the above battery charging variations.
The Inverters can be categorized by wave form into:
Step wave inverter
Instead of the sine wave delivered by an electric utility, this inverter produces a square wave. Because current is a switched, or turned on and off, the generated current had very abrupt changes and over time looks like a wave with square corners
Modified Waveform inverter:
The shortcomings of the square-wave inverter become most evident when you try to use it to run a motor. Ac induction motors draw a substantial current surge on startup. They really prefer sine-waves to square-waves and may overheat on the latter. AC induction motors also store energy during a portion of each cycle, which will create problems if not returned to the battery or otherwise controlled.
Pure sine wave inverter
A few true sine wave inverters have appeared on the market, This kind of inverter will run motors cooler and may offer less interference with radio and TV. However, they are inherently more complex and less efficient, so they may not be justified in many installations.
It can also be categorized by application into:
- Isolation inverter (which is supposed to be used in a isolated place which have no AC power supply. The inverter simply convert the DC voltage sourced from the battery or solar panels to the AC voltage).
- Grid inverter( The inverter not only convert the DC voltage to AC, it also distribute the AC power into the utility power grid, meanwhile, the inverter can get the AC power from the grid to charge the batteries. It is more common that in this application, the inverter is being installed with a solar panel system nowadays).
