The Survivor Class 2 transformer with short circuit and overload protection is capable of withstanding a direct short circuit in excess of 15 days, says the company. According to the manufacturer, the transformers are classified as inherently limited, which eliminates the need for external protection or problematic internal fusing. Also, it extends the range of Class 2 transformers, allowing them to be used in intermittent-duty applications that would cause the fuses or circuit breakers used by other manufacturers to open, claims the company. Models are available from 40 to 100 VA, with either a 60-Hz rating or a 50/60-Hz rating. Primary input voltages include 115 V, 115/120 V, 200/300 V, and 460 V, with 24-V output.
