Voltage Regulator vs. Interactive UPS vs. Online UPS

Read Time:6 Minute, 9 Second

Typically, we use Inverter circuits to convert direct current (DC) to alternating current (AC). We design the inverter circuit and manufacture it with high-speed solid-state switches to build UPS Equipments like APC Easy UPS 3M.

In the world there are many Types of UPS Equipment. Among them are following:

  • The Standby UPS equipment line,
  • Interactive UPS Equipment,
  • On-line hybrid Standby UPS Equipment,
  • Standby-Ferro UPS Equipment (Resonant Ferro UPS Equipment),
  • Double Conversion UPS Equipment,

However, in the market the most commercialized are only two. Among them are the interactive UPS ranging from 250VA to 3KVA and the UPS Online equipment. We marketed that from 1kva to 600kva, on which we focus this article.

What Is an Interactive UPS?

The Interactive UPS equipment that UPS markets are equipment. That, unlike other models or brands, make Voltage Regulator with several Taps or regulation steps, delivering more stable energy at its output, Transient Suppressor and Surge Suppressor. Interference (STSI), a high energy efficiency inverter and maintenance free sealed dry batteries.

What Is the Regulation Process of An Interactive UPS?

It first filters the power supplied by the electric power company. When there is a power outage, the inverter automatically comes on. And supplies power to the UPS equipment from the batteries with the appropriate voltage and frequency. It is important to keep in mind that, in this technology, the inverter enters only when there is a power cut.

Interactive UPS equipment is excellent protection for non-critical electrical situations. Such as those found in personal computers, Small Office/Home Office equipment and personal workstations.

Make the Interactive UPS equipment of several main blocks:

  • The Voltage Regulator,
  • Or Voltage Stabilizer,
  • The Rectifier or Battery Charger,
  • The Maintenance-Free Sealed Dry Batteries,
  • And The Inverter.

Important:

It is very important to keep in mind that the interactive UPS with voltage regulator delivers a variable regulated voltage. And at the output that can oscillate depending on the model between 102VAC Up to 130 VACS. Without this affecting computer equipment or equipment that does not require a high standard in power quality.

When the Interactive UPS start to work on battery, they deliver a modified sinusoidal wave at their output. However, this does not affect the operation of equipment. That does not require a high standard of power quality.

What Is the Autonomy Time of An Interactive UPS?

We typically design UPS for short bursts of energy lasting 10 to 15 minutes. This depends on to protect the load of electrical consumption. Technically, the consumption of an interactive UPS is towards directly proportional to the Load.

That is associated with it. And that implies that not all domestic devices (PCs, PCs, TV, sound control center) consume a similar measure of electrical energy. So, the independence of battery time that the UPS hardware conveys. When the electrical power comes up short relies to safeguarded the qualities of the gear.

What Is an Online or Double Conversion UPS?

They are Protection, Generation and Electrical Support equipment that performs a double conversion of the alternating electrical energy it receives. Transforming it into continuous and then to alternating again. In the same way, they are equipment that now in which the electrical fluid of the public network fails.

This generates electricity via a series of battery units. In addition, the connected equipment will have continuous electrical backup. And to the Regulated network of the Company. The regulated network has the function of distributing regulated electrical energy throughout the company.

Electrical Distribution

According to compliance with international standards and the International Electrical Code NTC 2050. This electrical distribution carries out through orange sockets with Hospital grade isolated ground. And with all the guidelines dictated by the Standard.

Due to its high reliability and energy efficiency, ONLINE or double conversion UPS technology is the ideal. And recommend equipment does for following:

  • Protect Servers,
  • Communications Racks,
  • Industrial Equipment,
  • Medical Equipment,
  • Clinical Laboratory Equipment
  • Or the equipment that we must protect due to its criticality.

With a good UPS with the highest energy efficiency with characteristics equal to or superior to those distributed by UPS.

EMI Filter:

Make inductors and capacitors with it. The main function of this EMI filter circuit is to reduce or filter electromagnetic interference.

Rectifier:

We use the rectifier circuit is to convert alternating current (VAC) voltage to direct current (VDC) voltage. Since the UPS has the battery inside. And the battery can store only VDC, it becomes necessary to convert the input VAC supply to VDC.

Dc Filter:

We use the DC filter circuit is to filter the impure DC current coming from the rectifier circuit. And use the filter circuit is to remove those AC components from the direct current (DC)

Battery:

We connected the batteries are with the output of the DC filter circuit. When the UPS is connected to the power supply, the battery will be charged by connecting the two stages in parallel.

Inverter Circuit:

The inverter has direct current at its input. But we need an alternating current (AC) supply at its output to drive the load. So, used the inverter circuit is to convert direct current (DC) to alternating current (AC). We have usually designed the Inverter circuit and manufacture with high-speed solid-state switches, such as MOSFET, SCR, IGBT etc.

Ac Filter:

We install the AC filter circuit at the output of the INVERTER just before charging. We use it to filter the impure alternating current (AC) coming from the inverter circuit.

Static Switch:

There is a static switch connected between the AC filter circuit and the critical load. That bi-directionally prevent electrical conflicts in the UPS power flow.

Static Bypass Switch:

We connect it between the critical load and the input main power supply. And after the EMI filter source. This switch allows or disallows the flow of power from the main supply to the load. We design brand with this system. This serves as additional protection against overload or short circuits in the UPS output.

What Is the Regulation Process for An Online or Double Conversion UPS?

We manufactured the Online UPS unlike the Interactive UPS. And with much more robust and advanced protections. Also being an online UPS always keeps your Inverter in Operation.

The first step is to Filter the energy supplied from the electric power company. When there is a power outage, the batteries automatically start supplying the appropriate voltage. And current and frequency to the load.

UPS Online equipment is an excellent protection for critical electrical situations. Such as those that occur in industry as following:

  • Clinics,
  • Hospitals,
  • Datacenters,
  • Call Centers,
  • Supermarkets,
  • Food Processing Companies,
  • Poultry,
  • Medical Centers,
  • Dental Centers,
  • Warehouses,
  • Printing Equipment.
  • Large Format,
  • Professional Servers

Important:

It is very important to keep in mind that the online or double conversion UPSs are the ones that sell and deliver a stable voltage. And can calibrated at its output whose values ​​ are between 100VAC, 110VAC, 115VAC, 120VAC or 127VAC.

What Is the Most Economic UPS?

As mentioned above, if we compare a 1 Kva Interactive Ups with A 1kva Online Ups. The Interactive UPS is much cheaper due to the design. And the needs in terms of electrical protection. However, design it with protection in mind. Like ideal electric for Home, small offices, or small businesses. And we do not require advanced electrical protections or long periods of autonomy in batteries.
