UPS System Connector Solutions for Data Centers

Uninterruptible Power Supply (UPS) systems protect mission-critical operations from power interruptions, voltage fluctuations, and outages. They provide instantaneous backup power, stabilize power quality, and ensure reliable performance for servers, storage, networking equipment, and other critical data center infrastructure.

Deliver seamless backup power during outages

Regulate and stabilize power quality

Protect sensitive equipment and data

Enable safe shutdown and restart

UPS DESIGN INSIGHTS

What Are You Designing Around?

Higher-voltage and modular power architectures can introduce additional connection challenges in UPS systems. Here are two areas to consider as you define connection requirements.

HIGHER VOLTAGE

Moving to 48 V or HVDC architectures such as ±400/800 V?

CHECK FOR:

✓

Shock & arcing risk — How will increasing voltage affect protection at the connection?

✓

Safe hot-swapping — Does the connection need to support safe mating or unmating while the system is energized?

✓

Touch protection — Does the design need to help prevent accidental contact with energized conductors?

✓

Service isolation — How will power be safely disconnected and de-energized during maintenance?

SCALABILITY / MODULARITY

Adding modular power assemblies or backplane connection points?

CHECK FOR:

✓

Backplane mating points — Are additional modules increasing the number of power and signal connections?

✓

Tolerance stack-up — Can the connection accommodate alignment variation across modular assemblies?

✓

Blind mating — Do modules need to connect reliably where direct alignment or visibility is limited?

✓

Cable reduction — Can branch connections reduce cabling and save space within the system?

What connectors are used in UPS systems? +

UPS systems use a combination of high-current power, board-to-board, wire-to-board, FPC, Ethernet, USB, and RF connectors. Hirose solutions include the DF60 and DF22 Series for higher-current power connections, FX30B and FX31 Series for board-to-board power, FH34 Series for HMI and control interfaces, and ix Industrial™, CX, and U.FL(A) Series for network communication.

Where are connectors used inside a UPS? +

Connectors are used throughout a UPS, including the AC/DC rectifier and charger, DC link and battery system, DC/AC inverter, HMI and control boards, cooling fans, battery monitoring systems, sensors, and network interfaces. Depending on the subsystem, these connections carry power, signals, or data between components.

Why is contact reliability important in UPS connector selection? +

UPS systems are designed for continuous operation, making reliable electrical contact important throughout the equipment. Hirose uses multi-point contact structures in select UPS connector solutions and combines them with application-specific features such as compact design, vibration resistance, and high-current capability to address different connection requirements.

What connectors are used for UPS battery monitoring? +

UPS battery monitoring systems use connectors for voltage sensing, battery management interfaces, signal routing, and related connections. The Hirose TB4 Series is one option for battery monitoring applications and uses a multi-point contact design to support reliable electrical connection.

How are connectors used in UPS cooling and control systems? +

Connectors link cooling fans, sensors, control boards, and related electronics inside UPS equipment. Hirose wire-to-board options for these interfaces include the DF11, DF51/DF51K, and DF62/DF62W Series, with options for secure locking, compact connections, and environmental protection depending on the application.
