DC Output Ratings
1.
Voltage: -42 VDC to -58 VDC, positive ground. Output voltage is factory set at -54 VDC.
2. Output Power and Current:
a) 2000 W (41.7 A) @ 200 VAC to 250 VAC input and -48 VDC output.
3. Output Characteristics: Refer to Figure 1 for a graph of output voltage vs. output current.
Figure 1: Output Voltage vs. Output Current
4. Power Derating Based on Input Voltage: The rectifier power varies with changes in input
voltage. It uses an advanced power limitation method. The lower input threshold is 85 VAC. The
rectifier can provide its maximum rated power (2000 W) as long as the input voltage is within the
range of 176 VAC to 300 VAC. Below 176 VAC, and down to 85 VAC, the rectifier will continue to
operate normally but will be in a power derating mode. The relationship between the output
power and input voltage is illustrated in Figure 2.
