New: ABB ACH580 Vertical Bypass Drives with E-Clipse Technology
When it comes to HVACR variable frequency drives (VFDs), two priorities dominate every project: maximizing uptime and minimizing installation space. The updated ACH580 Vertical Bypass Drive with ABB’s E-Clipse technology delivers both — without compromise.
Designed for mechanical rooms, retrofit projects, and harsh outdoor environments, this space-saving vertical bypass solution keeps critical HVACR systems running, even during maintenance or fault conditions.
If you’re specifying or installing HVAC bypass drives, this is the upgrade you need to know about.
Maximize Wall Space in Tight Mechanical Rooms
Space constraints are one of the biggest challenges in HVAC retrofits and new construction. The ACH580 Vertical Bypass Drive is engineered with a slim vertical footprint that preserves valuable wall and eye-level real estate.
Perfect for:
Tight indoor mechanical rooms
Retrofit HVAC upgrades
Space-sensitive installations
You get full bypass functionality in a compact, installer-friendly design.
Continuous Operation with Integrated Electronic Bypass
Downtime in HVAC systems impacts comfort, operations, and costs. That’s why the integrated E-Clipse microprocessor-based electronic bypass ensures:
Continuous motor operation during drive faults
Operation during VFD maintenance
Active communications in bypass mode
Full monitoring and supervisory control
Even if the VFD is removed, the system maintains stand-alone bypass control and diagnostics.
This isn’t just a bypass cabinet — it’s an intelligent control solution built for uptime.
Built for Indoor, Dirty, and Outdoor Environments
The ACH580 Vertical Bypass Drive is available in multiple UL-rated enclosure types to match your application:
UL Type 1 – Indoor Applications
UL Type 1 - Space savings for indoor mechanical rooms
Ideal for space-constrained mechanical rooms.
UL Type 12 – Dirty & Demanding Environments
UL Type 12 - Built to last in dirty, demanding environments
Designed to perform where dust, debris, dripping water, and oil are present — without routine filter maintenance.
UL Type 4X – Outdoor & Coastal Installations
UL Type 4X - Superior protection for outdoor and coastal installations
Corrosion-resistant construction protects against rain, snow, ice, and salt spray. Optional sun shield reduces solar heat gain.
From rooftops to parking garages to hospital mechanical rooms, there’s a configuration designed for your environment.
Advanced Diagnostics, Communications & Protection
The E-Clipse bypass platform provides powerful features that enhance reliability and simplify system integration:
Built-in BACnet MS/TP, Modbus, GP1, and N2 protocols
45+ points of bypass data and control
Plain English keypad with advanced diagnostics
Proof-of-flow (broken belt) detection
Single-phase detection and motor protection in both VFD and bypass
Voltage tolerance of +30% / -35%
Smoke control override compliant with UL864/UUKL
Seismic qualification (ICC-ES AC156) and HCAI preapproval
These features make the ACH580 one of the most robust HVAC vertical bypass drive solutions available today.
