Use of an external input line fuse is recommended: Use a 10A/125V slow-blow fuse. 2. For uncompromised operation, the base-plate temperature of HD1-300 must be kept below the maximum of +100°C. Good engineering practice in observation of that limit, including use of auxiliary heat sinks or forced air cooling, is entirely the responsibility of the user. 3. All measurements are at nominal input, full load, and +25°C, unless otherwise specified 4. Ripple and noise figures are maximum values. See application note below. 5. Peak-to-peak and RMS metering equipment must have a 20 MHz frequency response with probes and cables that maintain a frequency response of 20 Hz to 20 MHz. Output ripple and spikes are measured directly at the output terminals of the converter with a 0.1 µF ceramic capacitor. The probe ground band must make direct contact with the output return or the common terminal of the converter to prevent noise measurement errors.
