Florham Park, N.J., May 16, 2019 — ASCO Power Technologies, the world's leading provider of critical power solutions, announces the availability of its Sigma LT Control System for their trailer-mounted 5000 Series Load Banks. The Sigma LT digital control system can now be used to provide advanced control and data logging for ASCO’s Model 5505, 5605, and 5905 load banks.

The Sigma LT Control System offers best-in-class application flexibility, user-friendly features, and advanced functions. Every Sigma LT features a local control panel equipped with Digital ToggleTM switches for load bank operation. Unlike mechanical switches, Digital ToggleTM switches enable users to synchronize stepped load changes. The local panel also features full digital instrumentation for single-phase or three-phase applications. Users can conveniently change between single or three-phase applications by pressing a single switch. The control system automatically calculates and displays load values corrected for the selected mode.

The Hand-Held Controller’s optional Color Touchscreen maximizes the value of the Sigma LT Control System. The touchscreen allows users to link up to 25 load banks into a single load bank network. The networked load banks can be controlled together or individually. The Hand-Held Controller’s USB port can be used to download data and update software. Like the local control panel, the Hand-Held Controller offers full digital monitoring and control.

When equipped with the ASCO Gateway Module, the Sigma LT can also interact with common power and building monitoring systems. This module interfaces the control system with the ASCO PowerQuest® Critical Power Monitoring System and the Schneider EcoStruxure™ platform for unprecedented power system visibility and control.

“With the introduction of the Sigma LT on our 5000 Series Trailer Products,” said ASCO Product Manager, David Jesberger, “ASCO customers now have the industry-leading flexibility, networking abilities, and intelligent load profiling that the Sigma Control Solutions are famous for.”
