The Best Rack Components for Your Enclosure

Rack components are a key design consideration. The right components can come together to promote functionality and effectively secure critical equipment. Designing a quality electronics rack requires careful consideration of your application’s requirements.

Military & Defense

Military and defense applications rely on our electronic enclosures to protect mission-critical equipment in the field and during transport. We design our parts and products to comply with rigorous military specifications such as MIL-STD-167, MIL-STD-810, and MIL-STD-901D. Whether you’re concerned about corrosion resistance or environmental factors, there is a build that can meet your unique operational needs.

Electromagnetic interference (EMI) and shock (or vibrational impact) are key factors we consider when designing a rack for military and defense clients. Interference caused by inclement weather, nearby wireless devices, and other sources can disrupt functions in devices and equipment. Our ruggedized aluminum builds help protect against EMI and shock, as well as moisture, impacts, and vibrations.

Racks for military and defense are typically constructed from a medium or heavy-duty frame system with isolators to absorb shock and vibration. They may feature honeycomb panels, filters, or gasketing to increase functionality and shield electronics from EMI. We can also add ground studs to cabinet chassis and copper busbars for extra stability (per 810G requirements).

These types of applications should consider these types of accessories:

  • Cooling solutions (ex: liquid cooling)
  • Power distribution units (PDUs)
  • Environmental monitoring
  • Rackmount shelves and drawers
  • Security locks
  • Shock & vibration absorbers / isolation
  • EMI/RFI shielding

Best practices for implementation:

  • MIL-STD compliance: ensure all components meet relevant military standards for durability and reliability
  • Redundancy: incorporate redundant power suppliers and cooling solutions to ensure continued operation in critical situations
  • Customization: look for accessories that can be customized to fit specific operational needs and environmental conditions

Research & Testing Facilities

Rack enclosures play a crucial role in the research and testing industry, providing structured, secure and efficient environments for housing sensitive equipment. They shield from dust, moisture, and other contaminants, ensuring optimal operating conditions. Our racks come in various sizes and configurations, allowing for customization based on specific research needs. Using RETMA rails and a modular framework allows for unlimited vertical spacing configurations, as well as easy expansion and reconfiguration as research requirements evolve.

Common applications include housing servers and networking equipment to support data processing and storage; in laboratories to store testing instruments and provide a secure workspace; or in field testing conditions to ensure protection and accessibility.

These types of facilities should consider these types of accessories:

  • Cooling solutions (ex: blanking panels and fans) to help with airflow and efficiency
  • Cable management
  • Rackmount power strips
  • Environmental monitoring
  • Rackmount shelves

Best practices for implementation:

  • Scalability: ensure that your rack setup can grow and change with your needs without additional heavy investments
  • Security: lockable enclosures to prevent unauthorized access
  • Redundancy: consider redundant power supplies and network paths for critical systems

Energy & Utilities

Oil, gas, and utility applications depend on electronic enclosures to protect equipment from environmental hazards. Racks serve to house, protect and organize equipment essential for operations, monitoring, and control. They’re designed to accommodate various types of equipment including servers and control systems critical for energy generation, transmission and distribution. Common applications include housing control systems to enable real-time management of energy distribution; to protect and organize transformers, switchgear, and communication systems within a substation; and portable field operations in remote locations for temporary installations, monitoring, and data collection.

Our racks safeguard sensitive equipment from harsh environmental conditions, including dust, moisture and temperature fluctuations commonly found in utility settings. Customizable solutions can be designed to support cooling systems, ensuring the electronics operate with optimal temperature ranges.

These types of facilities should consider these types of accessories:

  • Cooling solutions (ex: liquid cooling and direct direct expansion systems; blanking panels)
  • PDUs
  • Environmental monitoring
  • Rackmount shelves and drawers
  • Security locks
  • Rackmount power monitoring
  • Adjustable RETMA rails

Best practices for implementation

  • Redundancy: ensure components have redundancy features where necessary, such as dual power supplies and cooling systems
  • Compliance: verify that components meet industry standards and regulations (e.g., UL, IEC, NEMA)
  • Integration: choose accessories that can integrate seamlessly with existing systems and scalable for future expansion

Power Distribution Units (PDUs) 101

What is power distribution?

Power distribution is facilitated through different pieces of equipment that take the power conditioned by your uninterruptible power supply (UPS) and send it to your electronic components. Power distribution solutions can manage and even control energy consumption, distributing power efficiently to help reduce your operating costs and increase reliability.

Types of PDUs Power Panel

There are several types of PDUs available but are often classified as either non-intelligent or intelligent.

Non-intelligent PDU

Basic PDUs: typically a power strip that accurately distributes the correct voltage and current to multiple outlets.

Monitored PDUs: visually displays the current electric information, but it can only be viewed locally and lacks remote capabilities.

Intelligent PDU

Metered input PDUs: displays metered power locally and over a secure network. Helps managers avoid overloading circuits and calculate Power usage Effectiveness (PUE).

Metered output PDUs: also displayed locally and over a secure network. Not only does it monitor power usage, but can identify the power consumption at the device, server and rack level.

Switched PDUs: similar features as the Metered output PDUs, while providing the control needed to power on / off switches to specific outlets. It increases remote capabilities and creates power sequencing delays that minimize the risk of inrush currents and allows operators to power off devices that aren’t being used.

Single-phase vs. three-phase PDU

This term describes the number of electrical phases that a PDU receives and transmits. Over the past few years, average power consumption per server or device has rapidly increased. The typical power required at a rack has increased from 2 kilowatts to 12 kilowatts and continues upward.

Cabinet vs. rackmount PDU

PDUs come in two form factors: floor standing / cabinet and rackmount.

A floor standing PDU is a larger, three-phase power distribution unit that comes enclosed in its own cabinet. They’re often used to take incoming power and distribute it to an individual rack or group of racks.

Rack PDUs effectively distribute power to racks where multiple outlets are necessary. Beyond the capabilities of a basic power strip, a rack PDU can be used in 120V, 200-240V environments with a variety of plug and outlet configurations.

PDU checklist:

  1. Number of power outlets needed – every device within your rack will require a power source
  2. Type of sockets needed – most devices are powered from C13 or C19 outlets using plug-in cables, but some PDUs are available with color-coded and locking socket outlets
  3. Phases needed – single and three-phase
  4. Power load needed – include a safety margin of 10-20%
  5. Type of mounting needed – smaller PDUs can be installed horizontally within a 19-inch wide frame, but others with a large number of power outlets may require vertical mounting
