The ASCO Series 300 Generator Paralleling Switchgear, available from 208 to 600 volts, is the first patented transfer switch-based paralleling system. It combines robust UL listed components in a resourceful design that brings added flexibility, reliability, and cost savings to any project.
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.
Because the SERIES 300 System controls synchronization and load sharing via bias signals to the voltage regulator and governor, our solution is not limited to specific versions of generator controls or the same manufacturer, allowing for more flexible expansion options.
ASCO Series 300 Generator Paralleling Switchgear Features
- Utilizes generator power for switching
- Compact and modular design
- Provides a window to metering, event and alarm logs, bus optimization and load demand applications
- Transfer switches are managed according to their priority blocks, with 4 priority blocks for a 2-generator system and 8 priority blocks for a 4-generator system
- Loads can be separated and assigned to block priorities according to their importance, with the intent of operating all online generators at their maximum efficiency
- Application will add or shed loads automatically according to the available capacity as determined by online generators
ASCO Series 300 Generator Paralleling Switchgear Benefits
High Reliability – Putting together the most reliable switching mechanism with the most sophisticated paralleling controls utilizing redundant communication networks results in a robust and reliable paralleling solution. Add to that service and support groups dedicated to standby and critical power for a superior level of assurance.
Easily Expandable – The Series 300 Paralleling System brings an unprecedented level of simplified modularity and expandability to a variety of applications and generators. With front access options and a footprint as small as 28”D by 38”W, the Series 300 can be designed into compact power generation configurations with as many as 4 engine generator sets.
Intuitive Operation – By bringing together, in one location, the paralleling controls for all generators and including a logical, easy to use graphic touch screen with intuitive fingertip selections, the Series 300 streamlines your operation and improves the reliability of your power for your application.
Optional CPMS Bundles – Accessories 150PC1 and 150PC5 allow effective management of the SERIES 300 PCS master and generator controls as well as downstream transfer switches and metering. It remotely provides visibility and insight of your power system’s health and performance.
