With the growing portfolio of electrical applications in modern buildings (like EVs, solar panels, home automation, ACs etc), many building owners are opting for 3-phase connection rather than single phase connection. However, the appliances in 3-phase buildings are subject to much more harsh electrical conditions than the ones in single phase buildings. Typical electrical problems in a 3-phase building are double phasing (which even many stabilizers don’t withstand), surges, voltage fluctuations, absense of phase line(s) etc.
APS is an advanced multifunction centralized voltage protection device for 3-phase buildings that provides comprehensive voltage protection for electrical appliances in the entire building. It is a state-of-the-art device with many other useful features. It reduces energy consumption and improves the lifespan of the appliances.
APS is designed, developed and manufactured in-house meeting the most stringent quality standards. It reaches our customers with the best in class guarantee and service support.

Smart Connectivity
APS completely eliminates the need for voltage stabilizers by managing voltage fluctuations centrally, protecting all your appliances (big or small). Your appliances can now be plugged in to any socket without bothering about cumbersome stabilizers.
The intelligent and automatic phase selection system is another key feature of APS. The computerized system inside APS analyses the quality of incoming phase lines in real time. It disconnects the unhealthy input phase(s) and allows only the healthy input phase(s) to the appliances.
APS has a built in surge arrester unit capable of protecting the home appliances from surges coming in through the phase lines. For example, a lightning hitting electrical lines results in a surge in all the buildings in that locality. This is a common reason for appliance damage.
The intelligent and computerized electronic system inside APS analyses the incoming phase lines. It detects any variation beyond the safe voltage operating range and cuts off the appliances in real time thus protecting them.
Double phasing is the most common reason for electrical appliance damage in 3-phase buildings. This fault occurs due to loose contacts (external to the building) on the neutral line while there is also a load imbalance in the 3 phase lines. With this fault, more than 350 V gets applied across your appliances resulting in heavy damages. This fault is often severe enough to burn the the conventional stabilizers and inverters. The intelligent system in APS protects the appliances by quickly disconnecting them.
In a building equipped with phase selector system, the fuse blown outs are not immediately noticed by the owner because all parts of the building usually remains powered. The load imbalance due to this leads to higher current flow in some of the input supply lines and may finally result in wires/contacts damages. APS detects fuse blown problem and alerts the owner.
A typical stabilizer draws about 8 watts. Since multiple stabilizers are used in a typical building, the total energy drain is substantial. However, APS provides protection for entire home by drawing low power ( less than 8 watts). Also the automatic phase selection feature reduces the number of charging & discharging cycles of the home inverter, thus reducing the total energy consumption.
APS has a digital voltage display (applicable for certain variants only). It shows the voltage values of all the three input phases.
Saves money
APS saves several thousands of rupees every year for the owners. And the product cost can be recovered in a few years.

APS - Frequently Asked Questions
Yes. APS fits in most TPN phase selector type DBs. We have installed APS in DBs of most well known brands. Please refer our photo gallery (in section “APS – Other relevant materials” below) for sample photos.
TPN DBs do not have enough space to fit in APS. In this case, you need to buy our external fix enclosure and install APS inside it. The external fix enclosure needs to be connected between the energy meter and the TPN DB. For details, please refer to the user manual in section “APS – Other relevant materials” below.
APS consumes less than 8 watts.
We have several APS variants with different loading capacities. The basic Model (APS Elite) handles 30KVA. And the maximum current rating per phase is 63 Amps. Please contact us for specific consultation needs related to your building.
We recommend setting up a bypass switch at the time of APS installation. This allows the user to bypass the APS in case it ever goes non-operational.
ELCB/MCB provides current based protection. And APS is for voltage base protection.

No. APS is not designed for 3-phase loads It is designed for 3-phase buildings with single phase voltage rated loads. However, we do have a custom model for three phase loads. Please consult with us.
All electrical appliances are designed to work optimally in a certain voltage operating range. Voltage fluctuations beyond this operating range slowly degrades the appliance and finally results in appliance failure over time. APS reduces this degradation by minimizing the voltage fluctuations to the appliances.
A typical stabilizer draws about 8 watts. Since multiple stabilisers are used in a typical building, the total energy drain is substantial. However, APS provides protection for entire home by drawing low power (less than 8 watts). Also the automatic phase selection feature reduces the number of charging & discharging cycles of the inverter, thus reducing the total energy consumption.
In case APS goes non-operational (except due to the damage of surge arrester unit as explained below) during the guarantee period, we replace it with a new APS completely free of charge.
The coverage doesn’t include the replacement of APS due to damaged surge arrester unit. Note that the surge arrester gets partially damaged every time a surge event occurs through the input supply lines. After being subject to a few surges, the surge arrester gets completely damaged and needs to be replaced. This cost of replacement is to be paid by the customer. However, the occurrence of surge is quite rare and hence not usually a big concern for our customers.
Yes. We do provide AMCs. Please contact us for details.
Yes. We have done several such installations. Please consult with us.
