Use of an external input line fuse is recommended: Use a 5.0A/125V slow-blow fuse. 2. 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 erroneous noise measurements. 3. Output = 5V/20A. 4. All measurements are at nominal input, full load, and +25°C, unless otherwise specified 5. Ripple and noise figures are maximum values. See application note below. 6. Preliminary data. 7. V2 output voltage trim for models HD2-100-4D and HD2-100-5D is limited to upward voltage adjustment. Ripple/Noise Reduction In applications with loads between two and three inches from the HD2-100 module, the circuit board’s trace inductance can be used in conjunction with a 47 µF, low-ESR capacitor across each load to lower ripple and noise to 50 mVpp. —2— POWER GENERAL HD2-100 Series Mechanical Outline and Output Configuration Dimension Notes Pin-Out Output Adjustment 1.
