ASCO Series 4000 Transfer Switches

Series 4000 Automatic and Non-Automatic Transfer Switches (30 – 4000 Amps and up to 600 VAC for Commercial Applications)

Categories: Accessories, ASCO, Transfer Switches

For Commercial & Industrial Applications

Transfer loads between alternate sources of power regardless of ampacity size efficiently with ASCO 4000 SERIES Power Transfer Switches made possible with reliable, field-proven solenoid operating mechanisms. Combined with programmable microprocessor controllers, they offer the most advanced method of transferring loads.

ASCO Power Transfer Switches are the standard of the industry. High-speed transfer of loads between alternate sources of power, regardless of ampacity size, is achieved by a reliable, field-proven solenoid operating mechanism. When combined with a programmable microprocessor controller with keypad and LCD display, they offer the most advanced method of transferring all types of loads, such as motors, electronic drives, UPS’s and microprocessor-based systems. 4000 Series Power Transfer Switches are available open or enclosed, in ampacity sizes from 30 through 4000 amperes with a limited selection of optional accessories.

4000 SERIES Microprocessor Controller

The 4000 SERIES microprocessor controller is used with all sizes of Power Transfer Switches from 30 through 4000 amperes. It represents the most advanced digital controller in the industry and includes, as standard, all of the voltage, frequency, control, timing and diagnostic functions required for most emergency and standby power applications.
Because of severe voltage transients frequently encountered with industrial
distribution systems, the microprocessor logic board is separated and isolated from the power board as shown below. This improves electrical noise immunity performance and helps assure compliance with the rigorous transient suppression standards highlighted below.

Typical Applications

Banking, Finance and Insurance
Broadcast and Entertainment
Other Critical Industrial/Commercial Applications

ASCO 5200 SERIES POWER METER
The ASCO 5200 SERIES Power Meter is a microprocessor based metering device that provides real-time measurements of single and three phase power systems. The Power Meter uses digital signal processing technology to measure voltage and current per phase; real, reactive and apparent power, and bi-directional energy. All measurements can be viewed locally with a backlit liquid crystal display and/or displayed remotely with ASCO PowerQuest® products.

Direct voltage input for systems up to 600 Volts AC can be monitored without the use of external potential transformers (PTs). Measures three phase currents and a fourth current input is available for measuring current in the neutral conductor. The Power Meter includes one discrete input for transfer switch position, eight general purpose discrete inputs, and four relay outputs for monitoring and controlling external devices.

DATA ACCESS

Eight digital inputs, four relay outputs.
Input/Output 15-character, user definable screen display for identification of input/output signals.

CONFIGURABLE DESIGNATIONS

Local – A four line, 20 character LCD backlit display.
Remote – With optional Acc. 72A or 72E and Power Meter monitoring systems.
Provides user programmable setpoints based on twelve metering and I/O parameters. Each setpoint allows the user to select the parameter, the trip & reset levels, the trip & reset time delays and the alarm type or relay output to trigger. This can be used for protective relaying and peak shaving applications.

INTEGRATED ATS FEATURES

When configured on load of ATS:

Displays ATS position.
Displays power data as a function of ATS position (normal/emergency).
Accumulates energy data separately for normal and emergency sources.
