SGCCTV UPS – KSTAR XP-RT2000S

2000VA / 1800W Online Double-Conversion UPS

Pure Sine Wave • Zero Transfer Time • Rack/Tower • 4 × 12V 9Ah Batteries

The KSTAR XP-RT2000S is a 2kVA / 1.8kW true online double-conversion UPS designed to provide stable, continuous power protection for CCTV, NVRs, servers, network switches, access control, telecommunications and other critical electronic equipment.

According to the supplied product catalogue, the XP-RT series uses online double-conversion with full digital control, together with cold start, generator compatibility, hot-swappable batteries, rack/tower installation and multiple protection functions.

Full Technical Specifications

These values come directly from the XP-RT1000S/2000S/3000S technical table on page 3 of the supplied catalogue.

True Online Double-Conversion UPS

The 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 Equipment

During 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 → Equipment

The 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 Capacity

The XP-RT2000S is rated:

2000VA / 1800W

with 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 Equipment

The 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 Batteries

The standard XP-RT2000S configuration shown in the catalogue uses:

4 × 12V 9Ah batteries

forming a nominal:

4 × 12V = 48V DC battery string

The 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 Output

The 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 Range

The specified input range is:

110–300VAC

with 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 Installation

The XP-RT2000S has a rack/tower convertible design.

It can therefore be installed:

Horizontally inside a compatible server rack

or

Vertically as a tower UPS

The 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 Monitoring

The UPS LCD provides operational information including:

Input Voltage
Input Frequency
Output Voltage
Output Frequency
Load Percentage
Battery Voltage
Internal Temperature
Remaining Battery Backup Time

LED indications include line mode, battery mode, ECO mode, bypass, low battery, overload and UPS fault.

Communication & SNMP Monitoring

The catalogue specifies RS232 as a communication interface, with:

USB • EPO • Dry Contact • SNMP Card

listed 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 Functions

The XP-RT series provides protection against:

Short Circuit
Overload
Overtemperature
Battery Overcharge
Battery Overdischarge
Output Low Voltage
Fan Fault

The UPS also provides audible alarm states for battery operation, low battery, overload and system fault.

Ideal for CCTV & Security Systems

A 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 System

When 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.
