China UPS Power Supply Manufacturer Offering Reliable Uninterruptible Power Solutions

Core Positioning and Product Advantages

Precision-Engineered for Diverse Applications: From compact DC mini UPS for routers and cameras to heavy-duty online UPS for data centers, our UPS power supply series is designed for network protection, emergency backup, industrial automation, and mission-critical operations. DC mini UPS units feature a compact, wall-mountable or desktop design with clean cabling and quiet operation, while online UPS systems are housed in robust cabinets with intelligent cooling for demanding environments.

Advanced Control Technology: DC mini UPS uses CPU-controlled circuits for stable voltage output; offline UPS employs CPU-controlled integrated power boards with automatic voltage regulation (AVR); online UPS utilizes DSP technology and double-conversion topology for zero-transfer-time protection. All models deliver reliable, consistent performance.

Safe and Reliable Battery Technology: DC mini UPS uses brand-new 18650, 26700, or 33140 lithium batteries (no recycled cells). Offline UPS uses maintenance-free sealed lead-acid batteries. Online UPS supports long-life battery banks with configurable quantities and smart charging. All units hold authoritative international certifications (CE, ROHS) and feature comprehensive protection including short circuit, overload, overheat, overcharge, and over-discharge protection.

Ultra-Long Service Life: With proper maintenance, KTAC UPS systems achieve long operational life—DC mini UPS batteries offer ≥2000 cycles (LiFePO4), offline UPS batteries last 3–5 years, and online UPS systems are designed for 10+ years of continuous operation. Stable long-term performance significantly reduces replacement and maintenance costs.

Smart Compatibility & Communication: DC mini UPS features multiple DC outputs (5V/9V/12V/19V), USB-C PD, and PoE; offline UPS offers optional RS232/USB/RJ45 communication ports; online UPS supports RS232/RS485, SNMP, dry contacts, and parallel operation. Seamless integration with existing systems and remote monitoring capabilities ensure easy installation and management.

Features include millisecond-level switching, multiple output ports, and brand-new battery cells.

Offline UPS (650VA–3000VA): Line-interactive UPS with simulated sine wave output, AVR, and 6–10ms transfer time. Models include UPS-650AK LCD (650VA/360W) through UPS-3000AK LCD (3000VA/1800W). Ideal for home offices, retail POS systems, small servers, and security systems. Optional communication ports enable automatic shutdown and remote monitoring.

Online UPS (10kVA–200kVA): True double-conversion online UPS with zero transfer time, pure sine wave output, and high efficiency. 

Two series available: High-Frequency EX 3C3 Series (10–200kVA) with DSP control, 0ms transfer, >95% efficiency, and up to 6 units parallel; Low-Frequency 3H3 Series (10–200kVA) with isolation transformer, 0ms transfer, >90% efficiency, and robust industrial design. Suitable for data centers, telecommunications, medical equipment, and industrial automation.

Flexible System Expansion Design

Parallel Expansion: Online UPS models support up to 6 units in parallel for capacity and redundancy expansion, enabling scalable power protection from 10kVA to over 1MVA. DC mini UPS and offline UPS are designed for standalone operation but can be deployed in multiple units for distributed protection.

Modular Battery Configuration: Online UPS allows configurable battery quantities (16–40+ units) to meet specific backup time requirements. DC mini UPS offers selectable battery capacities (5200mAh–60000mAh) for extended runtime. Offline UPS provides various battery configurations (12V/7Ah, 12V/9Ah) to balance cost and runtime.

Intelligent Battery Management: Advanced BMS and smart chargers optimize charge/discharge, extend battery life, and provide real-time status monitoring. Online UPS supports temperature compensation and self-test functions.

Key Application Scenarios

Home and Small Office: Protect routers, computers, monitors, and POS systems from power outages and voltage fluctuations. DC mini UPS and offline UPS provide reliable, affordable protection.

Security and Surveillance: Ensure continuous operation of IP cameras, DVR/NVR, and access control systems during blackouts. PoE-enabled DC mini UPS simplifies wiring and provides centralized backup.

Data Centers and Server Rooms: Online UPS delivers zero-transfer-time protection for servers, storage, and network equipment. Parallel configuration ensures redundancy and scalability.

Telecommunications and Industrial: High-frequency and low-frequency online UPS protect base stations, industrial controllers, PLCs, and medical equipment from power anomalies. Robust design withstands harsh environments.

Commercial and Retail: Offline UPS safeguards checkout counters, barcode scanners, and office equipment, preventing transaction interruptions and data loss.

Frequently Asked Questions

Q: What is the difference between DC UPS, offline UPS, and online UPS?

A: DC UPS directly outputs DC voltage for devices like routers and cameras, with millisecond switching and compact design. Offline UPS provides AC power with simulated sine wave and 6–10ms transfer time for general electronics. Online UPS offers true double-conversion with zero transfer time and pure sine wave output for mission-critical equipment.

Q: Can multiple UPS units be connected in parallel?

A: Online UPS models support up to 6 units in parallel for capacity and redundancy expansion. DC mini UPS and offline UPS are designed for standalone operation; multiple units can be deployed for distributed protection but not paralleled.

Q: What battery types are used in KTAC UPS systems?

A: DC mini UPS uses brand-new lithium batteries (18650, 26700, 33140) with LiFePO4 chemistry for long cycle life. Offline UPS uses maintenance-free sealed lead-acid batteries. Online UPS supports both lead-acid and lithium battery banks, configurable for specific backup requirements.

Q: How long does the battery last?

A: DC mini UPS batteries offer ≥2000 cycles (LiFePO4). Offline UPS batteries typically last 3–5 years. Online UPS batteries last 5–10 years depending on usage and environment. Regular maintenance and proper temperature control extend battery life.
