Features Of Three-phase Modular Ups Battery – Usage In Hospitals And Data Centers

Three-phase UPS is the formal choice for larger installations with critical loads such as data centers, industrial applications, and medical settings, as well as protecting equipment with machines such as lifts, pumps, and fans.

Three-phase UPS setup

3 phase modular ups battery use three separate conductors procuring three sinewaves, each out of phase and spaced 120° apart from each other, to contribute continuous power to the load. A three-phase system positively needs a minimum of four wires (three conductors plus one neutral), which facilitates the support of a single-phase or three-phase output.

Three-phase modular UPS battery

In various sectors

Power service is delivered by three hot wires and one neutral. The voltage between any phase or hot wire and neutral is still 120 V, just like at home or older data centers. But three-phase power moves the legs 120 degrees apart. The voltage between any two phases or hot legs is 208 V.

Three-phase systems provide nearly twice the power capacity of single-phase systems, but via lesser wires. Since most cabinets nowadays are dual-circuited, the difference in wiring demand doubles, escalating cost savings with three-phase power.


Commercial buildings especially use three-phase power. More actual power is distributed to the building with the same-sized wires and circuit breakers, which leads to significant electrical expense savings. The phase balancing is trickier.

Healthcare sectors

Power protection systems in medical institutions have high demands than those for commercial or industrial use. With all interconnected operations, an interruption to power delivery at a hospital for even just a few seconds can disrupt thousands of interdependent systems. Aside from being a harsh experience for patients, a disturbance to the power supply at a hospital can lead to equipment malfunctions, system corruption, hardware damage, and data loss. In extreme conditions, data centers in the healthcare sector require a dominant contingency power system to keep them running, which can only be achieved by a three-phase ups battery.

Features of three-phase battery

Conductor: The number of conductors in three-phase systems is different from that of others. As a 3 phase supplies power through three conductors.

Voltage: The phase-to-phase voltage for a three-phase system is 220V, and the phase-to-neutral voltage is 120V.

Efficiency: when the power demand is higher, 3-phase online UPS shows more efficiency to carry a larger load more safely.

Cost: The equipment in 3 phase online UPS system will have lengthier life expectancies and the transmission lines for 3-phase power, there is no need for the heavy gauge copper wires as single-phase UPS, thus, in the long run, three-phase UPS will be economically best.

Maintenance: The plug-and-play characteristic of these types of counterparts is a bit complicated to install and set up without the need for outside installation.

Application: Three-phase modular ups battery units are commonly used in large installations, such as data centers, and large industrial power applications with higher power or KVA requirements.
