Additional specifications include input to output isolation of 3000Vac, output ripple/noise at 150mV Pk-Pk (typ) (20 MHz BW), and efficiency @ FL of up to 76% (typ). All models are over-voltage (clamp type) and short circuit (continuous) protected. The units have an operating temperature range of -25°C to +50°C without derating and a storage temperature range of -40°C to 85°C.
