Description

UPS is short for Uninterruptible Power Supply , allows electrical load to keep running and provides power in the event of a power failure.

A UPS system utilizes DC power stored in the battery as its backup source. During normal operation, the power from AC mains is directly supplied to the output through a static transfer switch. At the same time, the AC is converted to DC to charge battery. When there is a power outage and primary supply breaks, the battery stops charging and the static switch transfers the output line to the inverter side very quickly. At the same time, the inverter starts drawing current from the battery which is then supplied to the AC load.

Su-vastika uses advanced Static switches in its Heavy Duty UPS that reduces switching time to just 2ms to 5ms , which is fast enough to prevent a computer and majority of sensitive equipment from resetting. Because of its strong R&D and experience of its able Mentor, Su-vastika understands the power back up need of its customers across industries and most importantly it’s our Patent Technology as well.

It has designed a range of state-of-the-art Heavy-Duty UPS starting from 10KVA to 500KVA (3 Phase) that provides.

• Protection to your machinery / appliances during power surges
•  High energy storage
• Fast switching technology
•  Negligible maintenance cost
•  Lifelong usage with long lasting batteries

Who can use a Heavy Duty UPS?

Anyone who needs to run High Capacity Loadswhere generators are being used, can run the same load on the Heavy Duty UPS too. There is a misconception that Generators can’t be replaced with the UPS. However, our Heavy-Duty UPS range is being used in almost every industry, from the hospital industry, to the IT industry. Our Three Phase power backup solutions are available from 10KVA to 500KVA range.

Applicable areas of 500KVA Heavy Duty UPS are:

• Big Factories/Plants
• Hospitals
• Universities
• Showrooms
• Multiple Apartments
• Shopping Malls/Complexes
• Large Hotels

UPS with my existing Generator?

Yes, it is compatible with generators. It can be used with the Generator in several ways.

• As a secondary power backup source or the areas where mains is not available at all. The Generator can be installed at the back of the Heavy-Duty UPS. OurArtificial Intelligence (AI) based software will automatically switches the generator ON in case of low battery. This allows you to keep your devices running on the generator, while the Heavy-Duty UPS charges simultaneously.
• As a power supply to charge batteries. Our Heavy-Duty UPS can withstand a generator’s uneven power supply and convert this power to a healthy, regulated power supply that charges your batteries.
• As a temporary power backup source. In the rare case of a complete battery discharge during a power outage, our Artificial Intelligence (AI) based software will automatically put your load onto the generator with zero switch-over time, bypassing the inverter temporarily, and allowing your existing generator to act as an extra backup source. The bypass is so fast you won’t even notice!
• There are few remote areas around the world where no grid supply is available at all hence there is a requirement of two generators as one generator can work continuously for 8 hours only, after which it needs rest so the combination of UPS along with the generator is an ideal combination as the battery charging can happen while generator is working and the generator load will shift for one to two hours on the Heavy Duty UPS after which generator can start again. This way one more generator in parallel can be saved.

Heavy-Duty UPS compared to the Generator?

The initial investment on machinery for both Heavy Duty UPS and Generator is almost same, however there is a significant difference in running cost, maintenance cost & effort.

• Running Cost: The Heavy-Duty UPS runs on batteries while the generator runs on diesel. If used for the same number of hours/day in a year, the cost of running the generator is almost six times more than the UPS!
• Maintenance Cost: The Heavy-Duty UPS running on Lithium batteries requires almost no maintenance compared to generators which require maintenance every 300 running hours by trained technicians.
• Manual Effort: Having trained technicians to carry out regular maintenance on every 500 hours increases the cost of running a generator further. The Heavy-Duty UPS on the other hand has mandatory checks by service engineers just once in a six months.

What infrastructure is required?

Infrastructure required depends on the type of battery being used and capacity. Smaller backup load requirements will require smaller spaces. spaces.

•  Sufficient ventilation for heat dissipation is needed for Lead Acid Batteries.
• There are no special requirements for Lithium and Sealed VRLA batteries.

The optimum temperature for all batteries is 40°C to 50°C. However, they can also withstand temperatures ranging from -10°C to 50°C.

What type of maintenance required? Is servicing needed?

The Heavy Duty UPS is designed to require little to no maintenance. However, at Su-vastika, we provide services to keep your products in top-notch condition: An AMC contract to service your UPS every 3 months, and battery upkeep is done regularly depending on the type of battery bank used. Our systems come with an online monitoring feature (Optional), and GSM and WIFI compatible applications that monitor the UPS and battery life. In case of any issues, alerts will be sent automatically, and the stored data can be checked on the display of the UPS. Training a Certified Electrician at your site, for maintenance of the Heavy-Duty UPS.

I have sensitive devices. Will they be safe if I use Heavy-Duty UPS?

Yes. Absolutely. Our Heavy-Duty UPS will not just keep your sensitive appliances safe, but it will actively protect them as well. We have developed technologies like Soft Start System and Automatic Voltage Regulation specifically keeping your needs in mind.

Soft Start System: Unlike traditional inverters, that allow a sudden inrush of current, which can be harmful to your machinery, our Heavy-Duty UPS gives power when the appliances are started for the first time. It gives voltage gradually so that your sensitive devices don’t get any jerk voltage or spikes. Switching time is so quick that the equipment will not stop if the mains power is disconnected. The soft start system increases and maintains the life of the appliances.

Automatic Voltage Regulation: Voltage fluctuations are common occurrences. Whenever there is Low Supply voltage or High Supply voltage, and supply rises or drops below the Safe voltage range, our Heavy Duty UPS seamlessly switches to the battery power, keeping all your machinery and equipment safe. Moreover, the power quality produced in Battery Mode is better than the power quality provided by the electricity distribution companies or by the government as our Heavy Duty UPS provides Pure Sine Wave output having THD ≤5% which is a far better quality power compare to generators.

How often does the battery need replacing?

Battery life depends on its usage. In practical terms, the power failure in a particular area will define the battery life of the system. Depending on the battery type, if the power failure happens occasionally and the duration is also very less then:

 Lithium can last for more than 10 years..
Other battery systems, if properly maintained, can last up to 5 years.

Our Heavy-Duty UPS is also equipped to prolong battery life and manage battery health:

• In case of Tubular and SMF batteries our advanced Six Stage Charging technology charges the battery in 6 stages, which helps avoid over-heating and loss of water-topping.
• The UPS prevents battery from being fully discharged, which extends battery life.

How long does a battery take to recharge after a power outage?

For short power outages batteries do not get discharged very quickly and will recharge extremely fast as well..

For power outages longer than 3 hours battery charging times depend on the battery type:

• Lithium batteries charge fully in 4 hours and 50% of its charging can be done in 1 hour.
• SMF and Tubular Lead Acid batteries take 8 to 10 hours to fully charge. If the Mains breakdown is small then the battery discharge is very less so that they get charged fast to give the 100 percent back up.

The Heavy-Duty UPS is solar compatible.

Is charging batteries with solar power faster than charging with electricity?

Battery charging will depend on the size of the solar panels installed and the size of the solar charge controller. In this case the Heavy-Duty behaves like an Off Grid Solar UPS and it can cut off the mains supply and run completely on solar and batteries. This

• Saves the cost of electricity
• Increases the backup time
• Charges the batteries simultaneously
