2.1.1 Test Equipment

High Voltage DC Voltage Source: Capable of 365 VDC to 410 VDC, adjustable, with minimum power rating 500 W, or current rating not less than 1 A, with current limit function. The DC voltage source to be used must meet IEC 60950 reinforced insulation requirement.

AC Voltage Source: Capable of single-phase output AC voltage 85 to 265 VAC, 47 to 63 Hz, adjustable, with minimum power rating 100 W and current limit function. The AC voltage source to be used must meet IEC 60950 reinforced insulation requirement.

DC Digital Multimeter: One unit capable of 0-VDC to 450-VDC input range, four digit display preferred; and one unit capable of 0-VDC to 20-VDC input range, four digit display preferred.

Output Load: DC load capable of receiving 0 VDC to 20 VDC, 0 A to 15 A, and 0 W to 300 W or greater, with the capability to display information such as load current and load power.

Oscilloscope: Capable of 500-MHz full bandwidth, digital or analog: if digital, 5 Gsps, or better.

Fan: 200 to 400 LFM forced air cooling is recommended, but not required.

Recommended Wire Gauge: Capable of 25 A, or better than #14 AWG, with the total length of wire less than 8 feet (4 feet input and 4 feet return).
