The SURVIVOR Class 2 transformer has patented short circuit and overload protection capable of withstanding a direct short circuit in excess of 15 days. All SURVIVOR transformers including the 75 VA and 100 VA models are classified as Inherently Limited. This eliminates the need for external protection or the problematic internal fusing. It also 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. These innovative transformers can significantly lower warranty costs while increasing customer satisfaction, making them ideal for medical instruments and devices.
