Full Technical Specifications – KSTAR XP-RT2000S

Note: Specifications can vary slightly by production revision and regional configuration. For project/tender submission, confirm against the exact supplied XP-RT2000S unit and approved datasheet.

True Online Double Conversion Technology

The biggest advantage of the KSTAR XP-RT2000S is its true online double-conversion architecture.

The power path operates approximately as:

AC Mains
↓
Rectifier / Charger
↓
DC Bus / Battery System
↓
Inverter
↓
Clean AC Output
↓
Critical Equipment

Because the protected equipment is continuously supplied through the UPS inverter, the XP-RT2000S can provide stable output even when incoming utility power experiences fluctuations.

This makes it particularly suitable for sensitive security and IT equipment.

0ms Transfer Time – Continuous Power Protection

The XP-RT2000S provides:

0ms AC-to-Battery Transfer Time

During a mains power failure, the UPS does not require the normal switching delay associated with basic standby UPS designs.

This is particularly valuable for:

• CCTV NVRs and DVRs
• Servers
• PoE network switches
• Network storage
• Routers and firewalls
• Access-control servers
• Security workstations

A momentary interruption can cause some equipment to reboot, interrupt CCTV recording or temporarily disconnect network services. An online UPS helps reduce this risk.

Pure Sine Wave Output

The KSTAR XP-RT2000S produces a:

Pure Sine Wave Output

This makes it suitable for professional electronic equipment including:

NVR / DVR
Server
NAS Storage
PoE Switch
Network Switch
Router / Firewall
CCTV Workstation
Access Control System
Video Intercom System

Pure sine wave output is especially appropriate for sensitive switch-mode power supplies and critical IT infrastructure.

4 × 12V 9Ah Internal Batteries

The standard XP-RT2000S configuration uses:

4 × 12V 9Ah Internal VRLA Batteries

The four batteries form a nominal:

48VDC Battery System

Nominal stored battery energy can be expressed as:

48V × 9Ah = 432Wh nominal

However, 432Wh does not mean that 432Wh is fully available to the connected AC equipment.

Actual usable runtime is affected by:

• Connected load
• Battery discharge rate
• Battery age
• Battery condition
• Ambient temperature
• UPS inverter efficiency
• Battery cut-off voltage
• Battery manufacturing tolerance

For this reason, UPS runtime should always be calculated using the actual equipment load in watts.

How Long Can the XP-RT2000S Last?

There is no single backup-runtime figure for every XP-RT2000S installation.

For example:

300W CCTV system will normally operate considerably longer than an 800W system.

Likewise, a system approaching 1800W will have a much shorter battery runtime.

When sizing a UPS, calculate:

NVR consumption

• PoE switch consumption
• IP camera consumption
• Network equipment
• Server / workstation
• Other critical equipment

Important PoE calculation

Avoid double-counting.

If the PoE switch specification shows:

Switch electronics = 30W
Connected cameras = 150W

then estimated switch input may be around:

180W + conversion losses

Do not add the same 150W camera load again after already including it within the PoE switch’s total input load.

Recommended Engineering Headroom

Although the XP-RT2000S is rated at:

1800W maximum

a professional design should generally avoid continuously operating the UPS at its absolute maximum rating.

Allowing reasonable capacity headroom can accommodate:

• Equipment startup conditions
• Future equipment additions
• PoE camera variations
• Battery ageing
• Unexpected peak loads
• System expansion

For critical CCTV and IT installations, UPS sizing should be based on maximum anticipated load plus suitable engineering reserve.

CCTV & Security System UPS

The KSTAR XP-RT2000S is particularly useful for security-system applications.

Typical CCTV Architecture

230VAC Utility Power
↓

KSTAR XP-RT2000S Online UPS

↓
PoE Switch
→ IP Cameras

↓
NVR
→ Surveillance HDD

↓
Router / Network Switch
→ Remote Monitoring

↓
Security Workstation
→ Live View / Playback

During a short mains failure, the UPS can maintain selected critical equipment according to the available battery runtime.

Why CCTV Systems Need UPS Protection

Without UPS backup, a power interruption may result in:

Cameras going offline
NVR shutting down
Recording interruption
PoE switch rebooting
Network disconnection
Remote monitoring failure
Unexpected HDD/file-system shutdown

UPS protection is therefore an important part of a professionally designed CCTV system.

However, an internal-battery 2KVA UPS should not automatically be treated as a long-duration backup system.

If the project requires several hours of operation, consider a long-runtime UPS, external battery bank or generator-backed power design.

Ideal for Servers & Network Equipment

The XP-RT2000S can also protect:

Servers

Continuous power helps prevent unexpected server shutdown.

Network Switches

Keeps critical LAN connectivity operating during short outages.

Routers & Firewalls

Helps maintain internet and network-security infrastructure.

NAS / Storage

Provides backup time for storage equipment and controlled shutdown.

PoE Switches

Can maintain both the switch and connected PoE devices, provided the complete load is correctly calculated.

Rack / Tower Convertible Design

The XP-RT2000S provides flexible installation as either:

Rack Mount

Suitable for:

19-inch server racks
CCTV racks
Network cabinets
Equipment rooms
Control rooms

or:

Tower Installation

Suitable for:

Office equipment
Standalone servers
Workstations
Small network systems

This makes one UPS platform suitable for different installation environments.

Rotatable LCD Display

The LCD panel provides operating information and can be oriented to suit rack or tower installation.

Typical information includes:

Input voltage
Input frequency
Output voltage
Output frequency
Load percentage
Battery voltage
UPS operating mode
Internal temperature
Battery status

This allows technicians to quickly check UPS operating conditions during maintenance and troubleshooting.

Wide 110–300VAC Input Range

The XP-RT2000S supports a wide input operating range of approximately:

110–300VAC

depending on connected load.

At full load, the accepted input range is narrower.

The wide operating range helps the UPS continue operating from utility power during certain voltage fluctuations instead of unnecessarily switching to battery mode.

This can help reduce unnecessary battery cycling.

ECO Mode for Energy Saving

The XP-RT2000S includes an ECO operating mode for improved efficiency.

This can reduce power losses where maximum double-conversion conditioning is not required.

For mission-critical CCTV, server and network applications, however, operating mode should be selected based on the site’s required protection level rather than energy saving alone.

Generator Compatible

The UPS platform can be incorporated into generator-backed installations.

Typical architecture:

Utility Supply
↓
ATS
↙ ↓ ↘
Generator
↓

KSTAR XP-RT2000S

↓
Critical CCTV / IT Equipment

The UPS can provide continuity while the overall backup-power system transitions between power sources.

For generator projects, confirm:

Generator capacity
Output frequency stability
Voltage regulation
Neutral and earthing arrangement
UPS input characteristics

before commissioning.

Optional SNMP Remote Monitoring

For server rooms, CCTV control rooms and unattended equipment rooms, the XP-RT2000S can be configured with suitable communication options.

An optional SNMP network management card can enable centralized UPS monitoring.

Depending on the selected hardware/software, monitoring may include:

Mains status
UPS operating mode
Battery condition
Load status
Power failure
UPS alarms
Fault notifications

This is particularly useful for multi-site CCTV and IT infrastructure.

Important

Do not assume the SNMP card is included as standard.

Confirm the exact communication interface and SNMP card requirement during quotation.

UPS Battery Maintenance

UPS batteries are consumable components and require periodic inspection.

Battery life depends strongly on:

Temperature
Battery quality
Discharge frequency
Depth of discharge
Charging condition
Age

A weak battery in a four-battery series string can affect the performance of the entire UPS battery bank.

When batteries reach end-of-life, it is generally advisable to test the complete string and replace all 4 × 12V 9Ah batteries as a matched set, rather than replacing only one old battery.
