NEW BERLIN, Wis – ABB releases the new ABB E-Clipse Bypass — ideal for wall mounting and/or fitting into air-handling units and pumping packages on all types of OEM equipment used in the HVAC industry.
Ideal Back-up
The new ABB E-Clipse Bypass is the first design to communicate, like ABB’s drives, directly with Building Automation Systems.
This introduction significantly extends ABB’s first E-bypass design, introduced in 1998. Worldwide, there are more than 100,000 E-bypass installations in operation. Further study of this market — its applications and requirements — resulted in the new product line, which is being introduced to the market at the international AHR (Air-Conditioning, Heating, Refrigerating) Exposition in New York.
ABB E-Clipse Bypass — Technology to the Next Level
The ABB E-Clipse Bypass takes the full digital microprocessor-based controls pioneered in the first E-bypass “to the next level — a seismic advance,” according to Mike Olson, manager, HVAC applications. “The technology incorporates new capabilities that answer the needs of the changing and evolving customer and market requirements.”
Available in a UL Type 1, UL Type 12 or NEMA 3R enclosure — and integrated with ABB’s ACH DriveIT Low Voltage 550 adjustable-speed AC drives — the two-contactor bypass features both a service switch that disconnects the drive for service, and a main disconnect switch or circuit breaker. The dual switch eliminates downtime, since the motor/load never needs to go offline; this back-up feature — ensuring uninterrupted operation — continues to make bypass drives the preferred choice among more than half of all commercial applications, according to ABB.
Common Protocols are Standard Feature; Control Through All Conditions!
The ABB E-Clipse Bypass includes the more common HVAC protocols as standard features. Included in every bypass shipped are Modbus RTU, Johnson Controls N2, Siemens FLN, and BACnet communications protocols. Other protocols, such as LonWorks, Profibus-DP, Ethernet/IP, Modbus TCP, DeviceNet and CANopen, are available as plug-in option cards.
This next-gen bypass technology also extends the serial communications for VFDs that ABB pioneered for the HVAC industry in 1994 — and resulted in more than 150,000 units (in the U.S., alone) connected to building automations systems, using these various communications protocols.
