Product Description

Kehua KR1000+ 1KVA Online UPS — Zero-delay power for systems that cannot afford downtime

Power cuts still crash servers, corrupt data, and damage hardware. Kehua KR1000+ 1KVA Online UPS targets that pain point with true online protection and zero transfer time.

This model sits inside the UPS IPS and Power solutions category, under Online UPS, trusted by offices and IT rooms across Bangladesh. PCB Store carries it for users who demand stable output, tight voltage control, and predictable backup.

Kehua KR1000+ 1KVA Online UPS overview and performance

Kehua KR1000+ 1KVA Online UPS uses double-conversion topology. Power flows through the inverter at all times. Output never shifts during input disturbances. Transfer time stays at 0 ms.

Rated capacity reaches 1KVA with a 700W load ceiling. The 0.9 power factor fits modern IT loads. Optional 1.0 PF support exists for specific configurations.

Voltage stays locked within ±1% across selectable outputs. Sensitive servers and network gear remain stable during brownouts and surges.

Noise stays below 55 dB. That level suits offices and rack rooms without acoustic treatment.

Electrical input control in Kehua KR1000+ 1KVA Online UPS

Input voltage tolerance runs from 120 to 295 VAC. This wide window matters in regions with unstable grids. The UPS keeps charging and regulating without dropping to battery.

Frequency auto-senses 50 or 60 Hz within ±10%. No manual switching needed during generator use.

Input power factor reaches ≥0.99. Upstream breakers see cleaner loads. Cable heating drops. Generator efficiency improves.

Output stability and protection behavior

Selectable output voltages include 208, 220, 230, and 240 VAC. Adjustment happens through the front display panel.

Protection logic reacts to:

• Low battery
• Overload conditions
• Short circuits
• Over-temperature events

Alarms trigger for abnormal AC input, UPS failure, and battery issues. Alerts remain audible and visible on the LCD.

Battery system and real backup time

Kehua KR1000+ 1KVA Online UPS uses a 24VDC battery bus. The system runs on two 12V 9Ah batteries.

At actual IT load, backup lasts 10 to 15 minutes. That window allows safe shutdown or generator takeover.

Charging current peaks at 1A. Batteries recharge steadily without thermal stress.

Battery performance stays stable within the defined operating temperature range.

LCD display and monitoring control

The front LCD display shows load status, battery condition, input voltage, and alarms. Technicians read values at a glance.

Communication ports support local and remote monitoring:

• RS232
• USB slot
• EPO port

Optional slot modules include SNMP and RS485 with dry contact. These options suit networked power rooms and managed IT racks.

Physical design and installation fit

The chassis measures 190 × 400 × 330 mm. Weight stands at 22.9 kg. The footprint fits floor placement or rack-adjacent setups.

Ventilation supports continuous operation. Internal cooling keeps components within safe limits when ambient conditions stay controlled.

Operating temperature ranges from -5°C to 40°C. Humidity tolerance reaches 0–95%, non-condensing.

Typical use cases in Bangladesh

Kehua KR1000+ 1KVA Online UPS suits environments where voltage swings occur daily.

Common deployments include:

• Small server rooms
• Network switches and routers
• Medical diagnostic equipment
• Financial terminals
• Industrial controllers

IT teams across Bangladesh prefer online UPS models for mission-critical uptime. PCB Store stocks this unit for those requirements.

Reliability and warranty terms

Manufacturer warranty covers 1 year for the UPS and 6 months for the battery.

Warranty exclusions apply under specific conditions:

• Damage from thunder or abnormal overload
• Insect entry inside the unit
• Ambient temperature not held between 20–26°C with dehumidification
• Placement in dusty or damp locations
• Generator use without proper battery charging
• Battery swelling from incorrect system voltage settings

Following these guidelines protects long-term reliability.

Why Kehua KR1000+ 1KVA Online UPS stands out

This model focuses on electrical discipline. Voltage regulation stays tight. Transfer delay does not exist. Input tolerance stays wide. These traits matter more than cosmetic features.
