Customer service, rock-solid dependability, and the
industry’s highest performance have made ASCO the
first choice in emergency power for more than 110
years. Our power transfer switches are used in more
emergency power backup systems worldwide than any
other. ASCO is the name behindmost of the technological
advances in transfer switch design, and we have more
patents than all other manufacturers combined. ASCO
transfer switches are the first choice for installations of
every kind, from homes and small businesses to the
largest financial data centers and hospitals in the world.
The SERIES 165-and every ASCO Transfer Switch-
meets or exceeds the stringent requirements of UL
1008, the only UL transfer switch standard. It even says so
right on the front panel. If you don’t see the UL
Automatic Transfer Switch label...you’re not getting the
best protection money can buy.
Generac is the only manufacturer of open transition switches to incorporate the two most common switching methods (inphase and delayed-transition) into the same ATS. Our inphase monitor provides safe, fast (160 msec) transfers between two live voltage sources when the source voltages are aligned (within 20°). If voltages are not inphase within an appropriate time, the system will automatically revert to the time delayed-transition transfer. If the inphase function is disabled, our GTS switches utilize delayed-transition transfer that allows load voltage to decay to a safe level before switching sources.
The Generac HTS transfer switch is a microprocessor-based design for operation in conjunction with the PowerManager® H-100 controller. HTS switches communicate via a RS485 communication link to the controller. Utility voltage and frequency are monitored by the HTS switch. Switching techniques are selectable for in-phase monitoring or delayed-transition. All timers and voltage set points are remotely programmable via GenLink® communications software.
The Generac MTS transfer switch is a microprocessor-based design for operation in conjunction with the Generac PowerManager® G-200 paralleling generator controller. The MTS switch has a 2 wire RS485 communication link to the system controller with a redundant 2-wire start should the communication link fail. Utility voltage is monitored by each MTS. Switching techniques are selectable for in-phase monitoring or delayed-transition. All timers and voltage set points are remotely programmable via GenLink® communications software.

(7) Generac RTS automatic transfer switches are designed
to operate with the digital control used on air-cooled
generators and the Generac R100 control used on liquid-cooled
QT series gaseous generators from 8 kW through
60 kW. The RTS transfer switch will operate only with the
Generac R100 controller. The 100, 200 and 400 amp open
transition switches are available in single and 3 phase
configurations for 120/240, 120/208 and 120/240 3 phase
at 100, 200 and 400 amp ratings and 277/480 at the 100
and 200 amp rating. It is available as a stand-alone switch
or for single phase with a built in 8, 10, 12, 14 or 16-circuit
load center to supply only those circuits that are essential
during an emergency. All standard and load center ...
