Power Switching & Controls for Business-Critical Continuity
4-hour protection no matter when trouble strikes ASCO S eries 300 Power Transfer Switches for Power Outage Protection Where would you be without a constant flow of electrical power? We often take for granted that power will always be around when we need it. In reality, power failures are very common. And when the power goes out, your business suffers. Power failures are unpredictable.
Typical Applications Telecom Agriculture In the telecommunications industry, providing a high level of service and dependability is crucial. Lost power means an interruption in service for your customers and lost business for your company. For instance, with cell sites scattered across a wide geographical region and in many remote areas, the chances of an interruption in power are increased, making Automatic Transfer Switches a valuable resource at each location.
Series 300 Power Transfer Switches Maximum Reliability & Excellent Value With a Series 300 Transfer Switch, you get a product backed by ASCO Power Technologies, the industry leader responsible for virtually every major technological advance in the Transfer Switch industry. The ASCO Series 300 was designed for one purpose–to automatically transfer critical loads in the event of a power outage. Each and every standard component was designed by ASCO engineers for this purpose.
Series 300 Power Transfer Switches Designed to Fit Anywhere The ASCO Series 300 product line represents the most compact design of automatic power transfer switches in the industry. With space in electrical closets being at a premium, the use of wall or floor-mounted ASCO Power Transfer Switches assures designers optimum utilization of space. All transfer switches through 2000 amps are designed to be completely front accessible.
Series 300 Microprocessor Controller The ASCO Microprocessor Controller is used with all sizes of Power Transfer Switches. It represents the most reliable microprocessor controller in the industry and includes, as standard, all of the voltage, frequency, control, timing and connectivity functions required for most emergency and standby power applications. Voltage & Frequency Sensing Adjustable three-phase, close-differential voltage sensing on normal source.
Series 300 Microprocessor Controller Battery to Maintain Engine Exerciser Clock Settings Re-transfer to Normal Adjustable Time Delay Simple and Accurate Adjustment of Voltage, Frequency and Time-Delay Settings Without Need for Meters and Variable Power Supplies Transfer to Emergency Adjustable Time Delay Dip Switches for Enabling Built-In Control Functions Serial Communication Port Customer Control Interfaces Fig.
Series 300 ATS Optional Accessories Accessory 11BG A programmable engine exerciser that provides for weekly or bi-weekly operation, includes one form C contact for source availability of normal and one contact for availability of emergency (contact rating 2 amps @ 30 Vdc, 0.5 amp @ 125 Vac resistive). The programmable engine exerciser incorporates a 7 day or 14 day time base with a digital readout display. Includes “with or without” load control selection for exerciser period.
Series 386 Non-Automatic Power Transfer Switches User-Initiated Control ASCO 386 non-automatic transfer switches are generally used in applications where operating personnel are available and the load is not an emergency type requiring automatic transfer of power. The power-switching mechanism and controller is the same hardware used on the highly reliable ASCO Series 300 transfer switches. ASCO 386s are furnished as standard with a momentary-type selector switch to initiate transfer and re-transfer.

Series 300SE Power Transfer Switch The ASCO Service Entrance Power Transfer Switch combines automatic power switching with the necessary disconnecting, grounding, and bonding required for use as service entrance equipment. The power transfer switch meets all National Electrical Code requirements for service entrance use. Transfer switches generally are installed at facilities that have a single utility feed and a single emergency power source.
