FAQs
for Amplon Series – Single-Phase UPS Systems, 1–10 kVA
Amplon UPS units primarily use a true on-line double-conversion topology. This means incoming AC power is continuously converted to DC and then back to AC, providing an isolated and regulated output. The benefit is that connected equipment receives a clean, stable sine-wave supply without any transfer delay when switching to battery mode. This architecture protects critical devices from power disturbances such as blackouts, voltage drops, or spikes with the highest level of power conditioning.
Yes. Many Amplon series models (especially the RT series and RT Pro series) are designed as rack/tower convertible units. They come with rack-mount hardware (typically fitting standard 19-inch racks) and also support vertical orientation as a tower. The LCD control panel on these units is often rotatable, so it remains readable whether mounted horizontally in a rack or standing vertically. This flexibility allows users to deploy the UPS in server cabinets or on the floor, depending on space and infrastructure requirements.
The standard runtime RT Gen3 UPS models include internal batteries sized for short to medium backup durations (several minutes at full load, which is typical to safely shut down equipment or bridge a brief outage). The “long backup” versions (often referred to as the R series in this range) are configured for extended runtimes using external battery packs. Long backup models usually have the same power electronics and rating as the standard units but either omit the internal batteries or use a different charging setup, allowing large external battery cabinets to be added. This makes the long backup variants ideal for applications that require significantly more backup time than the built-in batteries could normally support (for example, hours of runtime for critical systems during a prolonged power failure).
The Amplon RT Pro series uses an advanced power conversion design that outputs power at a 1.0 power factor (kVA equals kW). Essentially, the UPS can deliver the full apparent power as real power to the load. For example, a 3 kVA RT Pro unit can supply the full 3000 W without derating, whereas older designs with power factor 0.8–0.9 would only support 2400–2700 W at 3 kVA. The unity power factor advantage is that each UPS can support more equipment or higher wattage devices for a given kVA rating, which maximises the utilisation of the UPS capacity. This is especially beneficial for modern IT hardware and servers, which often have high power factor loads.
Amplon series UPS units are engineered for high efficiency. Depending on the model, typical on-line (double-conversion) efficiency ranges from around 90% up to the mid-90% range under nominal load. For instance, the RT Pro series can reach around 94% efficiency in normal mode. Additionally, most Amplon UPS models include an Eco or Economy mode, in which the UPS operates in a bypass configuration to achieve even higher efficiency (often 98–99%). In Eco mode, the load is powered directly from mains when the input is stable, and the UPS inverter remains idle but ready to take over if the mains deviates. This dramatically cuts losses and saves energy during normal operation, reducing electricity costs. Users can enable Eco mode in situations where the mains power is generally stable and a slight compromise in transfer time is acceptable.
Amplon UPS systems typically come with multiple communication options for monitoring and management. Standard features include a serial RS-232 port and/or a USB port that can interface with a computer running power management software. Many models also have a mini slot (or intelligent slot) that supports optional interface cards – for example, an SNMP network management card for remote monitoring over an IP network, or a dry-contact relay card for building alarm integration. The UPS units are also equipped with audible alarms and an LCD or LED display on the front panel, providing real-time status information (such as input/output voltage, load level, battery charge, and any alarms). This combination of local and remote monitoring capabilities allows users to supervise the UPS status, perform controlled shutdowns of servers, and receive alerts promptly if there’s any power event or if battery service is needed.
The Amplon 1–10 kVA single-phase UPS series is ideal for small to mid-scale power protection needs. Typical applications include protecting enterprise network equipment (like switches, routers, and small servers), telecommunication racks, security and surveillance systems (CCTV, access control), and point-of-sale or banking terminals. They are also commonly used in healthcare for protecting laboratory devices or clinic IT infrastructure, and in government or educational institutions for critical IT closets. Essentially, any environment that requires reliable power for loads in the kilovolt-amp range (from roughly 800 W up to 10 kW) can benefit – especially if the equipment is sensitive to power disturbances. The Amplon series is designed to offer high reliability and good performance in a compact footprint, making it a practical choice for offices, branch locations, clinics, and industrial control systems where three-phase industrial UPS solutions are not required.
The Amplon N series (which includes models in the 6 kVA and 10 kVA range, as well as the newer N Gen3 1–3 kVA models) focuses on providing very stable, continuous power for more critical or higher power loads. In the 6 kVA/10 kVA single-phase category, the N series units are typically tower-style UPS systems built for robust performance and can handle higher power in a single module than the RT (Rack/Tower) series. The RT series, by contrast, is available in lower power ratings (1–3 kVA for single-phase standard models and up to 10 kVA in the larger RT line) and is optimised for versatility in form factor (being rack-mountable). So, the key differences are in form factor and capacity: RT models excel in rack-mount flexibility for IT equipment at lower kVA ratings, whereas the N series covers both smaller Gen3 units and the bigger tower units up to 10 kVA, emphasising reliable power for critical applications. Additionally, certain technical distinctions exist – for example, the larger N series UPS often have robust chargers and possibly internal bypass designs suited for their size. In practice, a customer with a 10 kVA single-phase requirement might choose an Amplon N series tower unit, while a customer needing multiple 3 kVA units in rack form would lean towards the Amplon RT series.
