Century Star Series High Frequency Online UPS 1K-10K

· The 1-10KVA C series online high frequency UPS takes three-level technique and soft switch design.

· The active power factor correction(APFC) to make the input PFC can be higher as 0.99.

· The new design make our C series with high energy density ratio, reducethe UPS machine size very much, and also less occupy the space in the server room.

· The digital control make UPS with much more stable system, and also have the well ability of self-defensive and fault diagnosis.

· This series UPS can provide better solution for the different power problems, such as transient voltage sag, damped oscillation,high voltage pulse, surge voltage, harmonic distortion, noise wave interference, frequency fluctuation and others.providing more reliable protection for the application and UPS itself.

Full Online Protection in a Fraction of the Space

Let's be honest about something: most online UPS units in the 1–10kVA range are frustratingly big. You open the box, look at the rack you're supposed to install it in, and realize half your available U-space just disappeared. And it's not just the height—they're deep too. In a shallow network cabinet or a cramped corner of an office, that footprint hurts. You end up sacrificing equipment slots, making cable management harder, or even rethinking the whole layout just to accommodate the UPS.

The Century Star Series starts from a different place. Instead of accepting the usual bulk as a given, it uses three-level inverter technology paired with a soft-switching design to dramatically shrink the chassis. That combination runs the inverter cooler and more efficiently, which means less heat to manage and less heatsink mass needed. The result is a genuinely compact unit with high energy density—you get the full 1–10kVA rating in a box that leaves you room for the servers, switches, and storage you're actually trying to protect.

True Online Double Conversion, Just Smaller

It's still a genuine online double-conversion UPS. The inverter is always on, continuously regenerating a clean sine wave. Your equipment never touches raw utility power. No transfer time, no switching glitch. If you're protecting sensitive network gear, a server running virtual machines, or telecom equipment that logs every power anomaly, that architecture is the gold standard. The Century Star Series just delivers it without forcing you to clear out half the rack first.

Three-Level Inverter and Soft Switching: The Efficiency Engine

What actually makes the size reduction possible? Traditional two-level inverters switch hard between voltage states, which generates heat and audible noise. A three-level inverter smooths out those transitions, reducing switching losses. Then add soft-switching techniques—circuitry that minimizes the overlap between voltage and current during each switch cycle—and the inverter runs even cooler. Less waste heat means smaller cooling fans, less heatsink material, and a tighter overall package. Efficiency goes up, footprint goes down, and the unit doesn't scream at you from across the room.

Digital Control with Built-In Self-Diagnosis

The brain inside is a digital signal processor (DSP) that keeps the output locked tight regardless of what the grid is doing. Voltage, frequency, waveform—all monitored and corrected in real time. But beyond just stable regulation, the digital control gives the Century Star a practical self-defense ability. The unit runs continuous self-diagnostics. If it detects an internal fault, it can often isolate the problem and protect itself before a minor issue becomes a catastrophic shutdown. For IT teams managing remote closets or sites without onsite electrical staff, that early warning capability prevents a lot of midnight emergencies.

Active Power Factor Correction: Clean Draw, Lower Bills

On the input side, active power factor correction (APFC) pushes the input power factor above 0.99. In plain terms, the UPS pulls current from the wall in a clean sine wave that's closely aligned with the voltage. No reactive power bouncing around, no harmonic currents being dumped back onto the building's wiring. That keeps the electrical infrastructure happy—fewer nuisance breaker trips, less heating in the neutral—and it can shave a bit off your electricity bill compared to a UPS with poor power factor. When you're running the unit 24/7, those small savings add up.

Handles the Full Spectrum of Grid Garbage

Power problems come in more flavors than just blackouts. The Century Star Series is designed to deal with all of them:

`Voltage sags and brownouts that starve your equipment

`Spikes and surge voltages that can fry power supplies

`Harmonic distortion from nearby heavy machinery or cheap electronics

`Frequency fluctuations when the grid wobbles or a generator takes over

`Noise interference riding on the AC waveform

Your gear sees none of it. The double-conversion process strips all that out and delivers a fresh, stable sine wave every cycle. The UPS itself is also protected against these conditions, so it doesn't self-destruct trying to clean up a particularly nasty input.

Where You'll Use It

The Century Star slots into any deployment where power quality matters and space is tight:

`Server rooms and IT closets in offices, retail stores, or schools where the rack is already full

`Network cabinets in branch locations that are too shallow for a standard deep UPS

`Telecom shelters and base stations where floor space is at a premium

`Medical and lab environments with sensitive instruments that need online-grade protection

`Industrial control panels where a bulky UPS simply won't fit alongside the PLCs and drives

The through-line is simple: you need full online protection, but you can't afford to give up half the rack to get it. The Century Star Series is the space-conscious choice that doesn't ask you to compromise on power quality.

A UPS That Fits Your Rack, Not the Other Way Around

The whole category of 1–10kVA online UPS units has been overdue for a rethink on size. The Century Star Series proves that high energy density and full double-conversion protection can coexist without a massive chassis. Three-level soft-switching keeps it cool and efficient. DSP digital control keeps it stable and self-aware. And the compact footprint means you spend less time figuring out where to put the UPS and more time using the equipment it's protecting. If you're tired of online UPS units that demand more room than the gear they back up, this is the one that finally gets the proportions right.
