True Double-Conversion in a 19-Inch Form Factor

A rack-mount UPS can be a pain to live with if you pick the wrong one. Some are noisy, some run hot, and a lot of them lock you into a fixed battery setup that doesn't match the runtime you actually need. Then there's the hassle of trying to adjust charging current when you've got a bigger external battery bank—more often than not, it means opening the case, flipping DIP switches, or calling support.

The RC Series is a 19-inch rack-mount online UPS that sidesteps most of those annoyances. It's true double-conversion, so the inverter runs full-time and your equipment never sees the raw grid. But the part you'll appreciate day to day is how much you can tweak from the front panel without touching a screwdriver.

True Online, Not a Compromise

This isn't a line-interactive UPS squeezed into a rack case. It's a genuine double-conversion online UPS. The AC input is rectified to DC, the DC bus feeds the inverter, and the inverter continuously regenerates a clean sine wave. When the grid fails, there's no transfer time—the battery simply takes over the DC bus and the output doesn't twitch. For servers, storage arrays, network switches, or any gear that generates an event log when the power wobbles, that architecture is the gold standard.

Microprocessor control keeps the whole thing stable. The DSP samples voltage and current thousands of times a second, adjusts the PWM signals, and keeps the output frequency locked regardless of what the utility is doing. No analog drift, no calibration headaches. Just clean power that stays clean.

Adjustable Charging Without the Guesswork

One of the most practical features of the RC Series is something most manufacturers bury in a manual and hide behind a jumper: the charger current is settable directly from the LCD menu, anywhere from 1A to 12A. If you're running the standard internal batteries, you can leave it at the default. But if you've got a larger external battery cabinet—maybe you need 30 minutes of runtime instead of five—you can dial the charge rate up or down to match the battery bank's capacity and chemistry. Setting the wrong charge current is a sure way to shorten battery life, so being able to fine-tune it without opening the chassis matters.

Battery voltage is also configurable. That gives you flexibility if you're replacing an older UPS and want to reuse the existing battery cabinet, or if you have a specific cell count you're trying to match. You're not locked into a rigid string size.

1.0 Output Power Factor: Use What You Paid For

A lot of UPS ratings look generous on paper until you check the fine print. A 1000VA unit with a 0.7 output power factor gives you 700 watts. The RC Series delivers an output power factor of 1.0, so a 1000VA unit gives you a full 1000 watts. Modern servers and network gear with active PFC power supplies run close to unity anyway—finally, the UPS matches the load.

On the input side, active power factor correction keeps the current draw clean and in phase with the voltage. That means less harmonic pollution dumped back onto the building's wiring, fewer nuisance breaker trips, and a happier facilities electrician.

Wide Input Window and Generator Friendly

The input voltage range covers 110V to 300V. That's wide enough to ride through most brownouts and swells without ever touching the battery. The UPS just keeps regulating and passing power. It only switches to battery when the grid goes genuinely out of range, which preserves battery life and keeps you running longer during actual blackouts.

If you've got a backup generator, the RC Series plays nice with it. The wide frequency tolerance means the UPS won't reject generator power as "unstable" and bounce between battery and bypass. It accepts the rougher input, cleans it through the double-conversion stage, and delivers stable output to your rack. No constant beeping while the generator runs—the UPS just does its job.

Frequency Converter Mode for Mixed Grids

Need to run 60Hz equipment in a 50Hz country, or vice versa? The RC Series has a converter mode that lets you use it as a frequency converter. It takes the incoming utility power at one frequency, rectifies it, and then the inverter rebuilds it at the other frequency. This is useful for lab environments, test benches, or international deployments where the equipment doesn't match the local grid.

EPO for Safety-Critical Installations

On the larger models (6–10kVA), there's an Emergency Power Off (EPO) button. It's a hard-wired shutdown that cuts output immediately, no software delay. In a lab, a server room, or any installation where a safety event demands instant power-down, that's a requirement, not an option. The button is clearly marked and positioned where you can hit it without fumbling.

Communication That Fits Your Setup

The RC Series doesn't lock you into one monitoring protocol. You get a standard RS232 port, a USB port, and an SNMP slot for a network card. That covers local PC monitoring, serial communication for legacy systems, and full network-based management if you install an SNMP card. Whether your monitoring runs through a building management system, a NOC dashboard, or just a local shutdown utility on a server, there's a connection that fits.

Where the RC Series Lives

This is a UPS for standard 19-inch racks in:

`Server rooms and data closets where you want online protection without a tower on the floor

`Network cabinets in branch offices or retail stores

`Industrial control panels that need clean, regulated power in a rack-mount form

`Lab racks with sensitive instruments or mixed frequency requirements

`Telecom shelters where space is at a premium and reliability isn't negotiable

The through-line: you need true double-conversion protection in a rack-mount form, and you want the flexibility to adjust battery settings without calling a technician. The RC Series gives you that flexibility, plus a 1.0 power factor, a wide input window, and generator compatibility—all in a straightforward package that doesn't overpromise and doesn't frustrate.

Bottom Line

The RC Series Rack Mount Online UPS isn't the flashiest unit on the market, and it doesn't try to be. It's a solid, adjustable, true online UPS that fits a 19-inch rack and lets you control the charging parameters from the front panel. If you've ever been annoyed by a UPS that forced you to choose between inadequate runtime and a dead battery bank, the RC Series is the sensible alternative. Set the charge current, match the voltage, rack it up, and let it do its thing.
