“All three of the US’s largest public cell-tower companies have said they expect 2023 to be a big year for small cells, as 5G buildouts shift away from 5G macro deployments toward smaller mobile installations and telcos begin to finish their mid-band 5G rollouts.” – Jordan McDonald, Emerging Tech Brew

Featured Products

CWRS-4150A Power Shelf

CWRS-4150A Power Shelf

The CWRS-4150A modular power system provides up to 8KW of power in a 2U shelf. It is UL Listed and designed to meet NEBS requirements. It includes battery backup and two separate AC input ports, allowing for AC redundancy and smaller input cords.

NEspace™ Power Module

With up to 96% efficiency, the NEspace rectifier significantly reduces energy consumption and loss. The module is designed to lower energy costs and reduce environmental impact. Energy optimization results in a significant reduction in wasted energy, heat and CO2 emissions.

Small Cell Power Systems

High efficiency Cheshire Series power systems provide easy installation and maintenance. Equipped with full features and options, including battery backup with dry contact alarms, they are designed in compact, modular configurations (wall or pole mount installations), to accommodate high power requirements for indoor and outdoor applications.

Switching Power Supply

Higher efficiency (with lower heat dissipation) is the chief advantage of a switched-mode power supply, along with smaller size and less weight. Switch-mode power supplies are key to achieving highly efficient and reliable AC/DC or DC/DC power-conversion systems.

  • 1RU or 2RU configurations
  • Up to 9KW of power
  • Web server capability
  • Hot swappable
  • Automatic battery charging
  • Universal AC input
  • Low profile / High-density package size
  • High efficiency operation
  • High reliability
  • Low cost manufacturing
  • International Safety Approvals
