PowerPass UPS Bypass Systems

A UPS maintenance bypass switchboard allows critical loads to remain energized while the UPS is isolated for inspection, maintenance, repair, replacement, or testing. Properly designed bypass systems enable maintenance activities without disrupting power to downstream equipment.

PowerPass Slim is optimized for the smallest possible footprint and requires side or rear access for installation.

PowerPass Core provides the same functionality as Slim while allowing front-access-only installation.

PowerPass Pro adds 4-pole switching, advanced metering, expanded control functionality, and optional drawout breakers for applications requiring enhanced operational flexibility.

PowerPass Tile is a modular platform that supports maintenance bypass, input, output, paralleling, load bank, and distribution applications within a common architecture.

Choose Slim when footprint is the primary concern.

Choose Core when front-only access is required.

Choose Pro when 4-pole switching, advanced diagnostics, or drawout breakers are desired.

Choose Tile when modularity, scalability, load bank integration, or multi-UPS configurations are required.

Our engineering team can help determine the best architecture based on your UPS configuration, space constraints, and operational requirements.

Yes. PowerPass Tile can support both single-UPS and multi-UPS architectures, including paralleling systems for N+1, distributed redundant, and capacity expansion applications.

Yes. PowerPass Tile can be configured with factory-integrated load bank breakers and Scheme 29 interlocking systems to simplify commissioning, testing, preventative maintenance, and operational procedures.

Yes. PowerPass Pro is available with 4-pole MasterPact MTZ circuit breakers that provide complete UPS isolation, including neutral disconnection on 4-wire systems.

Yes. PowerPass Pro and Tile configurations are available with drawout MasterPact MTZ breakers to simplify maintenance and replacement activities without disturbing power or control cabling.

Yes. Depending on the application, PowerPass Tile can be configured with load-side lugs, distribution breakers, load bank breakers, or a combination of all three. PowerPass Slim, Core, Pro can be cabled to downstream switchboards with distribution breakers.

PowerPass systems can be equipped with a variety of power monitoring, energy metering, and communication solutions, including power quality metering, Modbus communications, and integration into building management and data center infrastructure management systems.

Yes. All PowerPass solutions are manufactured utilizing UL891 switchboard construction and are factory tested prior to shipment.

PowerPass solutions are manufacturer agnostic and can be designed to support virtually any UPS system, including single-module, parallel, and redundant architectures.

Absolutely.

While Slim, Core, Pro, and Tile cover the majority of UPS bypass applications, every facility has unique requirements. PowerStream's engineering team can develop a custom solution tailored to your electrical distribution, operational, maintenance, and space constraints.
