TNS 3 Phase Regulator: Expansion Options for Growing Businesses

As a growing business expands its operational scope, so must its electrical infrastructure. With added equipment like CNC machines, industrial ovens, compressors or production lines, the total electrical load increases and produces voltage instabilities which may harm sensitive electronics. The expensive and disruptive approach of upgrading the entire voltage stabilizer system during each expansion can be avoided with TNS-series of 3-phase voltage regulators, thanks to modular design capabilities, options to run them in parallel and scalable systems that expand to support your business growth. This article discusses four possible expansion strategies to safeguard your investment.

In conventional approach of voltage stabilization one needs to choose either oversized for current need at the expense of paying for non-utilized capacity for many years to come, or upgrade the existing unit when expanding, thereby wasting one's original investment. Modular capacity additions to the TNS series eliminates this dilemma.

You may start with a base unit for your current requirement – e.g., 50 kVA 3-phase voltage stabilizer for current operational need. When business expansion results in addition of new machinery, one is not obliged to replace the unit. Instead, addition of external current transformers or linking up of second TNS unit in parallel with the first, takes care of this demand while control unit seamlessly ensures balanced load distribution between units presenting a unified output to your facility. This 'pay as you grow' approach ensures that capital outlay is in line with demand, avoiding any wastage of investment as also expensive future upgradation.

Even in cases where your business has fluctuations in demand during different seasons, modular capacity addition enables running of only a minimum required number of modules, thus saving energy.

Addition to the incremental capacity features, TNS series support parallel operation for two equally vital purposes: redundancy and expansion of capacity.

Redundant (N+1) configuration protects against any disruption due to equipment failure. In such arrangement one extra unit of TNS beyond the actual need of your installation would be placed, if a unit fails, rest continue to deliver regulated power with no disruption. Data centers, medical manufacturing companies or continuous processing industries are sectors that can greatly benefit from this type of redundancy. The faulty unit may be withdrawn and attended while others carry on.

Load sharing expansion, multiple TNS units could be connected in parallel and divide the entire load amongst themselves automatically. Advanced software in these units monitor and regulates individual unit output current to share the total load of your facility evenly between units. This supports expansion to any capacity needed – say, two 100 kVA units could provide 200 kVA, four units could provide 400 kVA and so on. It even ensures energy savings.

As your business expands from a single facility to multiple locations or campuses, managing the voltage stabilizers in multiple installations poses a challenge. The TNS series come with communication facilities that can convert standalone regulators into a networked power quality management system.

Standard communication interfaces for these units include RS485 along with Modbus RTU protocol, which would link your units to your building management system, programmable logic controllers (PLCs) or central SCADA systems. From a single workstation you may then monitor the input/output voltages of your units, load currents, their internal temperatures and even alarm status of any of your TNS unit located anywhere.

Optional remote control and data logging features would allow you to make remote parameter changes, preset timed voltage modifications, log event for compliance reporting and even receive email/SMS alert in case of out-of-specification conditions. For businesses spread across different locations, this centralised monitoring facility would immensely save your cost for maintenance and support services and quickly diagnose issues when they arise.

Future-ready connectivity, Cloud enabled remote monitoring allows you to see your entire infrastructure power status from your PC, tablet or phone anywhere through the internet.

Addition to business expansion, there might be a need to operate with new voltage standards; a machine procured from Europe might be requiring 400V and your current setup might be using 380V or 415V. This would mean you might need separate transformers for each of these devices. The output voltage in TNS can be adjusted in range that is specific to each device.

Adjustable output voltage is standard in TNS regulators and through the digital interface one may set the standard output voltage anywhere between 380 V, 400V or 415V at 50 Hz, or between 208 V, 480V, 600V at 60 Hz, depending on requirement, without having to invest in additional transformers.

Multiple tap configurations. TNS are available with various tap configuration to cater to broad ranges of input voltage or precisely match the desired output voltage. So as you acquire new equipment, TNS will adapt and keep serving your needs without any hardware upgrades.

With over 20 years of expertise and 50,000 installations behind us we build every component in-house. The TNS series are the proud result of being the official drafter of the national industry standards and recognized "Industry Champions" by the government, delivering a quality, reliable and expandable power protection that will grow with you. From the sheet metal work to advanced software control, our engineers are committed to designing robust, seamless, and efficient units that will stand the test of time.

Your business expansion plans shouldn't involve an entire upgrade of your existing voltage stabilization infrastructure. The TNS 3-phase voltage regulators support scalability, offering modular capacity additions, parallel operation for redundancy and higher output capability, remote monitoring to efficiently manage multi-site operations and customised voltage output options to accommodate equipment with diverse requirements. Your TNS unit will grow alongside your business, protecting your current investment, whilst paving the way for future expansion.
