True Online Double-Conversion UPSThe major advantage of the XP-RT2000S is its online double-conversion architecture.Conceptually:AC Mains → Rectifier / Charger → DC Bus → Inverter → Pure Sine Wave AC Output → CCTV / Server / Network EquipmentDuring normal online operation, the protected equipment is supplied through the UPS conversion system rather than waiting for a power failure before switching to an inverter.When utility power fails:AC Failure → Battery DC → Inverter → EquipmentThe catalogue specifies 0ms transfer time from AC mode to battery mode, which is particularly useful for sensitive equipment that should not experience an interruption during mains failure. 2000VA / 1800W CapacityThe XP-RT2000S is rated:2000VA / 1800Wwith a 0.9 output power factor. This makes it suitable for combinations such as:CCTV NVR PoE Network Switch Network Router Firewall Server PC Access Control System Intercom System KVM Console Telecommunication EquipmentThe actual connected load should not simply be designed at the full 1800W rating. Appropriate engineering headroom should be retained for startup loads, future expansion and battery-runtime requirements.4 × 12V 9Ah Internal BatteriesThe standard XP-RT2000S configuration shown in the catalogue uses:4 × 12V 9Ah batteriesforming a nominal:4 × 12V = 48V DC battery stringThe catalogue specifies approximately 4 hours charging time to reach 90% capacity under its stated conditions. Battery runtime is not a fixed number of hours. It depends heavily on connected wattage, battery age, battery temperature, discharge rate, inverter losses and UPS low-voltage cutoff.For example, a 100W CCTV load will run substantially longer than a 1000W server/PoE load on the same battery set.Pure Sine Wave OutputThe XP-RT2000S provides a pure sine-wave output, with voltage regulation specified at ±1%. This is preferable for sensitive professional equipment compared with low-cost standby UPS products using stepped or simulated sine-wave output.Wide Input Voltage RangeThe specified input range is:110–300VACwith 176–280VAC at 100% load. A wide input operating range can reduce unnecessary battery operation during voltage fluctuations, depending on load and operating conditions.Rack Mount + Tower InstallationThe XP-RT2000S has a rack/tower convertible design.It can therefore be installed:Horizontally inside a compatible server rackorVertically as a tower UPSThe catalogue also shows a multifunctional bracket and rotatable LCD panel, allowing the front display orientation to suit the installation method. At only 86.5mm high, the chassis is approximately a 2U rack format.LCD MonitoringThe UPS LCD provides operational information including:Input Voltage Input Frequency Output Voltage Output Frequency Load Percentage Battery Voltage Internal Temperature Remaining Battery Backup TimeLED indications include line mode, battery mode, ECO mode, bypass, low battery, overload and UPS fault. Communication & SNMP MonitoringThe catalogue specifies RS232 as a communication interface, with:USB • EPO • Dry Contact • SNMP Cardlisted as optional interfaces/functions. For server rooms and remotely managed CCTV installations, an appropriate SNMP card can be particularly useful for network-based UPS monitoring.The exact SNMP card model and software compatibility should be verified before quotation.Multiple Protection FunctionsThe XP-RT series provides protection against:Short Circuit Overload Overtemperature Battery Overcharge Battery Overdischarge Output Low Voltage Fan FaultThe UPS also provides audible alarm states for battery operation, low battery, overload and system fault. Ideal for CCTV & Security SystemsA typical security installation can be:230VAC Mains↓KSTAR XP-RT2000S Online UPS↓PDU↓NVR + PoE Switch + Router + Firewall + Access Control + Server↓CCTV Cameras / Network / Security SystemWhen mains power fails, the UPS maintains power to the critical equipment from its battery system.This can help prevent immediate shutdown of the NVR, PoE cameras, network switch and router during short-duration power interruptions.10 Key Benefits 2000VA / 1800W capacity True online double-conversion topology 0ms AC-to-battery transfer time Pure sine-wave output 4 × 12V 9Ah internal batteries Wide 110–300VAC input range Rack / tower convertible installation Generator compatible Hot-swappable battery design Optional USB / EPO / Dry Contact / SNMP connectivity 10 Frequently Asked Questions1.
