Explore our premium grade OEM & ODM custom uninterruptible power supply portfolios
Established in 2015, Shenzhen REO Power Co., Ltd. has established itself as an elite global UPS manufacturing hub located in Shenzhen, China. Our engineering team, headed by a CTO with over 20+ years of dedicated ODM/OEM power electronics experience, leads the market in designing and supplying highly resilient uninterruptible power systems.
We operate with the clear objective to not merely assemble products, but to co-create custom solutions that build our clients' local market dominance. From high-frequency double-conversion systems to customized healthcare diagnostic power reserves and off-grid solar infrastructure, our products provide unparalleled power stability to clients across 100+ countries.
"By merging rigorous testing methodologies with flexible mechanical design configurations, REO Power guarantees a continuous power ecosystem for industries that cannot afford a millisecond of disruption."
The massive expansion of cloud computing, regional micro-data centers, and local edge computing architectures has completely transformed global demands for power backup topologies. The traditional, bulky tower-mounted UPS systems are rapidly being phased out in modern computing environments, giving way to space-optimizing 19-inch rack mount configurations. A standard rack mount unit allows administrators to integrate power backup systems seamlessly inside server enclosures alongside blade servers, network switches, and critical SAN storage components.
Key shifts defining the modern rack-mount UPS ecosystem include:
Traditional Lead-Acid (VRLA) batteries are being replaced by Lithium-ion alternatives due to a 3x higher power density, significantly longer lifecycle (exceeding 10 years), and a massive reduction in overall rack weight loads.
Advanced thermal management allows manufacturers to cram high-capacity online double-conversion units (up to 3kVA or even 10kVA) into standard 2U or 3U form factors, leaving more space for core computing units.
Modern procurement demands native SNMP cards, Modbus-RTU, and cloud-based management dashboards. Technicians require remote shutdown capabilities, real-time monitoring of load metrics, and predictive cell analytics.
Furthermore, global energy volatility is demanding higher operational efficiencies. Real double-conversion online systems, which process incoming AC to intermediate DC before feeding pure, clean AC back to systems, are achieving efficiency levels upwards of 95% in High-Efficiency (HE) Modes. This not only preserves delicate silicon components but significantly lowers ongoing carbon footprints and utility expenses for data center operators.
Global procurement executives face critical challenges when choosing rack-mount UPS vendors. Beyond initial pricing matrices, long-term operational success depends heavily on total cost of ownership (TCO), build quality, and compliance with national power grids. Power characteristics vary significantly across boundaries, requiring adaptive equipment platforms.
Enterprises operate across regions with distinct electrical environments. For instance, the Americas demand 110V/120V single-phase or split-phase (110V+110V output) systems, while Europe and Asian economies standardise on 220V/230V systems. A reputable OEM supplier must offer flexible wide input voltage windows (e.g., 55V to 150V for 110V models) to minimize battery discharge during minor sags, extending cell lifespan.
Strict quality certifications are non-negotiable for commercial deployment. Shipments entering the European Union must carry CE and IEC/EN 62040 certifications, while North American systems need to meet UL 1778 standards. Partnering with Shenzhen REO Power guarantees all items are manufactured in strict alignment with international CE, IEC, and ISO9001 quality guidelines.
As enterprise operations expand, their power profiles scale accordingly. Purchasing managers seek modular hot-swappable UPS topologies, which allow quick expansion without shutting down operational servers. This flexible redundancy design ensures zero downtime and minimizes upfront capital expenditures.
At Shenzhen REO Power, we embrace Factory 4.0 technologies to guarantee consistent output quality, cost-efficiencies, and rapid scalability. Operating 10 specialized production lines across two bases, we maintain a robust capacity of 80,000 UPS units per month. This massive output prevents shipping delays, even for large enterprise purchase orders.
Our manufacturing philosophy combines automated processes with multi-tiered diagnostic testing to eliminate defects before packaging:
As a leading factory in Shenzhen, Shenzhen REO Power leverages more than 20 years of experience to tailor systems for our business partners. We customize hardware housing, firmware metrics, and packaging options, converting custom concepts into scalable retail products.
Uninterruptible power backup is critical across numerous environments. 19-inch rack-mount configurations adapt easily to diverse operational settings:
Protects highly sensitive diagnostic imaging tools, such as ultrasound systems and MRI networks, from voltage sags. This prevents digital image corruption and keeps patient data protected.
Guarantees constant power to PLC units, smart robotic arms, and diagnostic systems. This avoids costly assembly line stops caused by voltage drops.
Provides critical power backups to remote cell towers, smart highway control points, and distributed processing hubs, ensuring high network uptime.
We deploy automated assembly and verification systems to deliver reliable equipment
Custom design adaptations guided by industry-leading power electronics experts.
Strict verification steps at every stage of the circuit board assembly line.
Dual production bases supporting high volumes and quick lead times.
True double-conversion online UPS systems provide zero transfer time (0ms) because they continuously convert incoming AC power to DC and then back to clean AC. This isolates the load from grid fluctuations, including voltage spikes, sags, frequency variations, and harmonic distortions. Line-interactive models, on the other hand, exhibit a 4ms to 8ms transfer delay when switching to battery power, which can reset sensitive servers.
Most early electronic component failures (infant mortality) occur during the first few hours of operation under thermal stress. Shenzhen REO Power runs an active 8-hour burn-in cycle at full load on 100% of our units. This isolates defective silicon, solder links, and components, ensuring only highly reliable systems leave the facility.
Our R&D team configures custom control boards and transformers to handle regional demands. This includes split-phase systems (220V input / 110V+110V output) and dedicated low-voltage 110V/120V systems with wide voltage input ranges. This prevents unnecessary battery drainage in regions with fluctuating voltage.
Yes. Through our ODM services, we customize internal firmware and communication cards (SNMP, Modbus-RTU, dry contacts). This allows the UPS units to integrate seamlessly with your existing data center management dashboards (DCIM) and network monitoring setups.
We offer custom-built lithium-ion (LiFePO4) battery packs, featuring integrated battery management systems (BMS) for safety and longevity. These packs operate reliably for over 10 years, support fast recharge rates, and reduce the overall rack load weight compared to traditional lead-acid alternatives.
With 13,500 square meters of production space, REO Power maintains the production efficiency required to fulfill high-volume orders. Our systems support global logistics and comply with regional energy regulations, ensuring smooth custom clearance processes.
