Staffing, supply chain issues and workplace changes are the challenges facing FMs
Facility managers can now, upon the introduction of the ASCO Series 300 Generator Paralleling System, consider pre-packaged transfer switch-based power systems for paralleling generators as an alternative to circuit breakers. The first of its type for load management for mid-tier installations, the ASCO Series 300 system, which brings high-power capabilities to mid-tier installations, is capable of paralleling 2 to 4 gen-set installations and managing 4 to 8 transfer switch load blocks at distributed data centers, commercial and telecom operations, oil and gas processes, and healthcare, government, agricultural, public, and educational facilities.
The ASCO Series 300 system takes an innovative approach to paralleling that utilizes generator power for switching and automatic controls and features a graphic touch screen as a convenient window to metering, event and alarm logs, and other data. The system, which brings together the paralleling controls and contactors for two generators into a single section for efficient use of space, is an economical alternative to the traditional switching capability of two circuit breakers.
The robust pre-engineered compact system, which is UL 891 listed, enables managing generators by runtime usage, assigned priority, or load requirement. It also includes the ability to distribute power by load prioritization and to control load bus optimization, generator load demand, and generator power metering.
The ASCO Series 300 incorporates a reliable, high-endurance ASCO Closed Transition Transfer Switch mechanism that represents a patented and innovative approach to paralleling. The system combines the transfer mechanism with the most sophisticated ASCO load distribution and control technology, originally developed for mission-critical, highly-engineered installations.
the ASCO Series 300 is available from 208 to 600 volts. “Because it eliminates job-specific engineering for either prime or emergency power applications that require paralleling two, three or four gen-set installations, the ASCO Series 300 system can be configured quickly for fast-track delivery,” says Bhavesh Patel, vice president, Global Marketing, at ASCO. “It can synchronize, parallel, and provide load sharing for a wide range of gen-sets, of different sizes and manufacturers using bias signals to the voltage regulator and governor. This provides needed flexibility to facility managers when they plan power expansions and equipment replacement.”
ASCO Series 300 features that ensure power continuity from automatic controls include managing generators by runtime usage, assigned priority, or load requirements, and distributing power by load prioritization. The system also can manually add and shed loads, manually start gen-sets and connect to the load bus.
The efficient, intuitive operator touch screen provides fingertip access to data and graphics for monitoring and control with minimal navigation. Screens include metering, event and alarm logs, bus optimization and load demand set up, and manual paralleling. Password protection allows individual account management and auditing as well as privilege assignments.
