​ASCO Series 300 Generator Paralleling System

Redefining Parallel Systems

The Series 300 Paralleling System, available from 208 to 600 volts, is the first patented transfer switch-based paralleling system. Tested and listed per UL 891, it combines robust UL listed components in a resourceful design that brings added flexibility, reliability, and cost savings to any project.

Overview
Control at your fingertips


 
The core paralleling switching mechanism of the Series 300 Paralleling System is a field proven ASCO Closed Transition Transfer Switch (CTTS). By combining the high reliability and long endurance life of the ASCO switching mechanism with advanced synchronizing and power management controls, the result is a robust, economical, compact, and effective paralleling system.

All the power controls, switching mechanisms, bus, metering and user controls are integrated into a compact UL 891 listed switchboard. This provides a more reliable system solution as critical components are independent and located separately from the engine-generator sets for ease of operation and service.

Features

 

 

ASCO innovation has also led to the development of a Power Management option with a robust tool set that improves overall operation and efficiency.

  • Load Management – A unique feature that allows for up to four levels of load control. Priority one loads are given maxi­mum protection by allowing lower priority loads (four, three, and then two) to shed first.  
  • Generator Management – The Series 300 Paralleling System’s generator management feature will automatically start and stop generators as needed to maintain a preset spinning reserve or safety margin between the actual load consumed and the total power available from all running generators.
  • Start Next Generator on Alarm – The Series 300 Paralleling System automatically communicates with the genset control system to seamlessly maintain your critical loads.
  •  Run Time Management – With this capability, generators can be set to automatically start and stop to control run time.
