Asco Power Technologies’ Sigma LT is a portable control system designed for load banks. The handheld controller, which features a 4.3-in. color touch screen, networks up to 25 load banks using CAN bus communications protocol. Operators can monitor and control all networked load banks or a single unit in the network, up to 800-ft away. The capability to vary, accept or reject load on a single unit within a network from a remote controller allows data centers to easily simulate hot zones to determine how an HVAC system reacts to temperature changes at specific server rack locations. A robust, aluminum case protects controller components. The touch screen displays 3-phase voltage, power, current, and frequency readings, and selected load.

It also provides de-rated loading when the working voltage is less than load bank nominal voltage. Data logging and statistical data can be downloaded to a USB flash. In local mode, the Sigma LT features digital toggle switch control with LED display. Individual load step LEDs and an integrated, one-second delay synchronize load step changes, producing clean load changes not possible with conventional toggle switch technology. The on-board controller features toggling for 3 phase voltage and load selection, metering, local and remote operation and operational mode, and a connection for the remote controller and other load banks.
