The P-Series of variable frequency drives by Cerus have an energy management bypass option for HVAC systems. Courtesy: Cerus IndustrialCerus Industrial Inc. has enhanced its P-Series line of variable frequency drives (VFDs) with an energy management bypass (EMB) option. The option assures uninterruptible operation of customers’ HVAC systems, even if the drive is taken out of the loop, including reprogramming or maintenance operations. With integrated real-time ANSI grade power metering and BACnet communications, the P-Series accurately measures consumption in both VFD and bypass mode to +/-1%. The P-Series also provides all the advanced motor protection in bypass mode that would typically only be available through the VFD. With integrated metering and programmable option-setting via an external keypad, the series offers a lower cost and safer-to-use solution to the measurement and verification requirements for establishing U.S. Green Building Council LEED certification. Other bypass solutions require external meters and modifications to be made by opening the panel, exposing high-voltage connectors.
