Automatic Transfer Switch
200 amp, 120/240V, 1-phase
When you require a complete basic automatic transfer transfer switch, we have the solution. The Ronk Vigilant series is designed to UL 1008 and has all the necessary delay timers, voltage sensing, frequency sensing, and generator programmable exerciser clock. Assembled in USA .
The Ronk Vigilant® Automatic Transfer Switch automatically transfers critical loads in the event of a power outage. All units come standard as NEMA 3R, UL listed 1008. The Vigilant® consists of a simple, rugged design while maintaining the flexibility required to meet the needs of residential, agricultural and commercial applications..
Galvanized Corrosion Protection
Standard on all Vigilant® enclosures – this duplex coated, galvanized G90 grade steel meets American Society for Testing and Materials (ASTM) standard A653, with a service life of more than twice that of regular steel.
The easy–to–use, 7–day exerciser clock gives full control over day and time. The exerciser clock and indicator lamps are both accessible from outside the transfer switch – no need to open the door.
Logic Control Board
At the heart of every Vigilant® automatic transfer switch lies our logic control board. It provides transfer switch control function with simplicity, flexibility and durability. Features include:
— Powered from genset battery for isolation against line transients
— Integrated voltage and frequency sensing
— Adjustable transfer delays using on-board potentiometers
One of the best comprehensive parts warranties in the industry.

1) The start time delay prevents nuisance generator starts during momentary utility power variations; transfer time delay allows generator set to stabilize before load is applied; retransfer delay prevents needless power interruption if return of utility power is momentary; stop delay allows gradual generator set cool down; undervoltage sensing of utility supply provides reliable starting of generator set during brownout conditions.
2) This switch is not service entrance rated. This generally means that you need a service entrance rated disconnect between this switch and your utility meter.
