The P-Series of variable frequency drives by Cerus now have an energy management bypass (EMB) option to keep HVAC systems running without interruption and has integrated ANSI grade power and BACnet communications. Courtesy: Cerus IndustrialCerus Industrial, Inc. has enhanced their P-Series line of variable frequency drives (VFDs) with an Energy Management Bypass option (EMB). The new option assures uninterruptible operation of customers’ HVAC systems, even if the drive is taken out of the loop for some reason, including reprogramming or maintenance operations.

Cerus’ EMB architecture reflects an all new approach to bypass design. With integrated real time ANSI grade power metering and BACnet communications the EMB accurately measures consumption in both VFD and Bypass mode to +/- 1%. The EMB also provides all the advanced motor protection in bypass mode that would typically only be available through the VFD (OV/UV, ground fault, phase loss, phase reversal, and belt loss protection).
