Trystar introduced a line of compact, portable automatic transfer switches (ATSs) with models rated at 200/400/600/800 and 1,200 amps and a small footprint. Designed for applications requiring an automatic transfer of power between mains and backup generators in case of mains power failure, it features an advanced design that eliminates nearly all wiring inside the enclosure to improve reliability and reduce maintenance requirements. In a typical application, the ATS is connected to a pair of portable generators feeding a single output. Switching between generator A and generator B is fully automatic. If generator A has a failure, or runs out of fuel, generator B is started by the ATS to pick up the load. The presence of a technician on-site 24/7 is not required for most situations. All models in the Trystar ATS line feature dual 480/208-V capabilities that can be selected on the fly via the touch screen. Rental generators and ATSs are commonly used for many different applications ranging from industrial site maintenance to backup power for critical facilities. Having that capability “on-the-shelf” makes the rental industry a key resource for a broad range of customers who need the capability to integrate portable power into their operational and maintenance programs.
The ATS touch screen displays event logs, including on/off, voltage change, transfers and, more. It also monitors KVA and KVAH plus amperage, voltage and wattage, and has a Modbus interface to enable remote monitoring of the switch. Additionally, it can be programmed with preset transfer times to switch inputs between multiple generators.
Standard features include cam lock input and output connections, dual inputs with a common output, and two-wire auto start for portable generators. Inputs are via male 16 series panel mounts (BK/BK/BK/WT/GN) and outputs are via female 16 series panel mounts (BK/BK/BK/WT/GN). The heavy-duty aluminum cabinet is housed in a steel cage with lifting eyes and fork pockets and can be moved with a standard pallet jack.
