The HiPass bypass package is designed for use in crucial applications so that no system downtime will occur. In HVAC applications, this allows heating or cooling to be maintained at all times, the company says. The package's terminal strip allows access to the HiVac drive's intelligent inputs, analog inputs, and building automation systems connections. It has a NEMA 1 side-by-side wall-mountable enclosure. The HiVac inverters can be used for variable-torque applications such as fans, cooling towers, and pumps. Features include PID control, anti-windmilling, intelligent terminal systems, three programmable output relays, and RS485 communications.
