Online UPS

Online UPS
What is "Online" in an Online UPS?
In the case of a regular inverter, the load (appliances and electronic device like computers, air conditioners, etc.) is directly connected to the mains. The power backup comes into play only when the mains go off.

In the case of an Online UPS, the load is connected to the mains through the UPS. Therefore the UPS is "Online" and the current always passes through the UPS itself.

How can Online UPS act as a Stabilizer
An Online UPS not only provides constant power backup, but it also works to improve your power supply. When the mains are on, it converts the AC (Alternate Current) into DC (Direct Current) and then reconverts it to AC. This removes the fluctuations and other disturbances present in the mains current, and protects your load. You can say it acts as a stabilizer for your load. This process is called 'Double Power Conversion'.
Security Check for your Current!
Double Conversion is like a security X-ray machine installed at an airport. The luggage going in through the entry is like mains AC. It is converted to DC and corrected for fluctuations and disturbances, just like the X-ray machine scans for suspicious items in the luggage. The output belt is like the pure AC current which is then transferred to the load.
How quick is an Online UPS?
Your Online UPS takes next to no time in switching on! Because the UPS is already online, the switchover time from mains to UPS in case of a power cut is zero. Zero Switchover Time makes the Su-Kam Online UPS the first choice when it comes to mission critical devices, where even a fraction of a second matters. For example, in a hospital, where sensitive medical equipment must always runs at specified voltages and power. Even at home, power disturbances may damage high-end electronic equipment like home theatre systems LCD/Plasma TV etc. Any break in supply or fluctuation can cause problems. Therefore, an Online UPS is absolutely critical, which ensures no break in power even in the case of a power cut.

Have you ever experienced the "cashless" problem at the ATMs. You may have put in your
PIN and desired amount, but the ATM transaction is cancelled. Even a millisecond of delay
in power backup can cause such problems. With an Online UPS installed at ATMs,
this problem can be easily solved!
How does an Online UPS protect the load?
Your Online UPS not only provides you power backup when you need it, but it also protects the load from disturbances or fluctuations. It does this by a process called Galvanic Isolation.

This means that there is a complete physical separation between the Input and Output. This is important, because any disturbance in the mains supply is not allowed to pass through the separation and travel to the load. In an industrial environment, the level of power distortions can be very high. Also, even at home, sometimes heavy electrical work in neighbouring areas like welding work etc. can disturb the power supply. Galvanic Isolation ensures maximum security for the load in such circumstances. In fact, with Galvanic Isolation, the Output can be grounded, in accordance with to international and local standards.
How can you keep an eye on your Online UPS?
Su-Kam offers you what no other Online UPS can. With Su-Kam UPS systems, you can actually control and monitor the UPS performance. This can be done through the Power Doc UPS monitoring system, which is a unique innovation by Su-Kam. This ensures maximum safety for high-risk applications like satellite systems, air traffic control systems, internet nodes, bank transactions, etc. It also protects your system from valuable data loss, interruption, errors, crashes or shutdowns.
How does the Power Doc work?
The Power Doc works with the help of a simple software installed in your PC called the Power Manager. This software acts as a transmitter that keeps you constantly updated about your UPS system.

  • The Power Manager constantly updates information regarding the output voltages, battery voltages and other important parameters.
  • The software keeps a log of important data like input and output voltage, input and output frequency, battery voltage, etc. so that the user can check the UPS performance at any time. This can also help predict any future problems.
  • The user can shut down the system automatically without individually switching off each PC. In fact the user can also prioritise the shutdown procedure allowing for a sequential shutdown of various system components, thereby protecting critical data and also unsaved files.
  • The software uses the standard TCP/IP communication protocol and supports all operating systems including Windows.

Software Functions
Graphical Monitoring of the UPS status: An easy to use powerful tool that allows monitoring and controlling the UPS systems. Input Voltage, Input Frequency, Output Voltage, Output Frequency, Battery Status, Load Status and Overload Status can be automatically monitored by it. There are graphical versions for both Windows and Linux. Detailed Display of all the UPS Data: Provides on screen, all the data required to make an accurate and speedy diagnosis of the UPS operation. Alarm Notification via e-mail and SMS: Can be configured to automatically notify an alarm via an e-mail or SMS message. In case of any critical error, it pops up the message on screen. Programming the UPS Commands: The commands normally carried out by the users are programmed so that these are performed automatically e.g. shutting down and switching the server back on, UPS battery test, etc.

Remote Monitor your UPS!

You can also remote monitor your Su-Kam Online UPS! In fact you can monitor a large number of systems spread out over a large area right from your office desktop. To know more, read on.
How does my Su-Kam UPS have extra stamina?
The Su-kam UPS is like a long distance runner. It has a Heavy Duty Charger that allows for faster charging. The faster the battery can be charged, the bigger the battery you can use. Therefore, the UPS can deliver sustained power for longer periods of time. It is like a long distance runner who utilizes minimum energy to deliver maximum performance.
How do I choose my Su-Kam UPS?
Su-Kam Online UPS systems comes in two ranges, namely the IntelliQ and the Sinclair-I Series. The IntelliQ Series operates at lower frequencies and the Sinclair-I Series works at higher frequencies. In fact, the IntelliQ Series comes in three different phase options:

  • 1 phase in - 1 phase out
  • 3 phase in - 1 phase out
  • 3 phase in - 3 phase out
