What’s a Heavy Duty UPS/Industrial UPS or High Capacity inverter? Why do people call them Heavy Duty or Industrial UPS? The UPS device converts AC to DC and DC to AC energy. An uninterruptible power supply (UPS) or uninterruptible power source is a continual power system that provides automated backup electric power to a load when the input power source or mains power fails. A UPS differs from a traditional auxiliary/emergency power system or standby generator in that it will provide near-instantaneous protection from the input power.https://en.wikipedia.org/wiki/Uninterruptible_power_supply The power remains uninterrupted as the Mains Power is present or not present does not make any difference as the UPS keeps the computers or other IT equipment running uninterruptedly in case of power failures or during voltage variations as well.
Heavy Duty, as the name suggests, is the Heavy Duty UPS/Industrial UPS, which can run higher loads and run big machines or a lot of computers simultaneously, along with other loads like printers, and fans Lights. Air Conditioners, Microwave ovens, treadmill, Fridge TV etc without any break. So one can run the heavy equipment or put all the home or office load on this. These Heavy Duty UPS are different from High Capacity Inverters as Inverters have a switching time. Hence, the equipment and devices switch off when the power goes and then switch on after a second, but in the Heavy Duty UPS, there is no break whatsoever, and all the appliances and devices work uninterruptedly. These High capacity Inverters and heavy Duty UPS come in two categories Single Phase to Single Phase power (IP-IP) and three phases to three-phase power(3P-3P). You need 3 Phase Power called Phase Heavy Duty UPS or 3 Phase high Capacity Inverter to run the higher capacity motors or lift motors. High-capacity inverters are power inverters; an inverter or inverter is a power electronic device or circuitry that changes direct current (DC) to alternating current (AC).[1] The resulting AC frequency obtained depends on the particular device employed. Inverters do the opposite of rectifiers which were originally large electromechanical devices converting AC to DC.https://en.wikipedia.org/wiki/Power_inverter.
High Capacity Inverters or heavy Duty UPS are installed in Hospitals, Schools, Shopping Malls, Multistoreyed buildings, Office complexes, Hotels, Colleges, Industries, Airports and Railway Stations etc. The Price of heavy Duty UPS and the Price of industrial UPS and the Price of Heavy Duty UPS are almost similar.
The Parameters to choose before buying High Capacity Inverter or Heavy Duty UPS:
- The Pure Sinewave waveform and Power Quality: When the heavy-duty UPS works on the battery mode or Inverter mode, then the waveform on different types of loads changes as the THD, which is total harmonic Distortion, increases on different types of heavy loads like Heavy machinery with a low power factor so one should see that the Heavy Duty UPS should have THD below 5% in the worst condition. The THD is of Voltage and current separately, and the current THD is affected the most with low Power factor motors or any other such load.
- The Isolation Transformer: Heavy Duty UPS High Frequency or Low Frequency based technology has two types. In Low frequency-based technology, an Isolation transformer is important for the reliability of Heavy-duty UPS, especially in areas where the power fluctuates, and there are more power cuts. This is the only technology that helps users get stable power from Isolation transformer-based heavy Duty UPS.
- Switching time plays a very important role as the power to switch when the Mains power is cut and the continuity of power during the power cuts and when the power is back. So the computers, TVs, or servers should not get any power break when the switching occurs. So the switching time should be as low as less than five milliseconds will be an ideal switching time where even lifts and escalators also keep working without any break.
- Input Voltage and Frequency Variations limits: The Voltage variations limits need to be taken care so the Low cut and High cut voltage settings along with the frequency variations cut off are important features.
- Generator Compatibility: In Heave duty UPS the generators are used in the back for supporting the longer power cuts, so when the power of the UPS is on the low battery than the generator should start working through the command from the UPS Generator is controlled through the Heave Duty UPS.
- Overload and Short circuit: There should be an Auto restart feature in heavy-duty UPS in Overload conditions. The UPS should be able to take the Short circuit on full load for a Short circuit.https://suvastika.com/whats-an-auto-overload-and-short-circuit-restart-feature-in-inverter-ups/
- Digital Warranty: This is an important must-have feature for any heavy Duty UPS.https://suvastika.com/digital-india-and-digital-warranty-in-inverter-ups-industry-used-per-pay/
- Bidirectional technologyhttps://suvastika.com/new/wp-admin/post.php?post=3569&action=edit&classic-editor=1
- IOT Wi-Fi and Bluetooth The IOt-based or Wi-Fi and Bluetooth-based mobile applications are very important to control the Heavy Duty UPS/industrial UPS. This feature is a modern-day requirement as the heavy Duty UPS has many parameters to monitor and control like Input Voltage, Battery charging condition, Load percentage, backup time, Overload, Short circuit and low battery warning etc.
- Lithium battery compatibility: Lead Acid based battery like Tubular and SMF battery technology is changing very fast to Lithium based battery technology.https://suvastika.com/lithium-battery-option-in-inverter-ups-solar-pcu/
- Charger Capacity: The Heavy duty UPS should have a charger that can be adjusted per the battery capacity. Suppose one wants to install a higher-capacity battery bank. In that case, the charger should be able to charge the higher-capacity battery bank, which is important when installing a lithium battery bank as they need fast charging.
- Costing: The price of Heavy-duty UPS having an Isolation transformer, High capacity inverter and Industrial UPS with an isolation transformer are similar.
