3.1 ZXD030 S480 Rectifier

3.1.1 Rectifier PartsIn the ZXDU58 B121 system, the rectifiers convert AC to DC.

For the appearance and structure of the ZXD030 S480 rectifier, see Figure 3-1.

Figure 3-1 ZXD030 S480 Rectifier

3.1.2 Rectifier IndicatorsFor the indicators of the rectifier, see Figure 3-2. For a description of the working status ofthe indicators, refer to Table 3-1.

l Normally, only the power indicator is lit.l In case that output current limit occurs, the power indicator flashes.l In case that a system fault occurs, the alarm indicator is lit. For example, in case of

under-voltage protection, the power indicator is not lit and the alarm indicator is lit.l In case a rectifier fault occurs, the fault indicator is lit.l When the power and alarm indicators flash at the same time, a program is being

downloaded.

Chapter 3 System Modules

3.1.4 Output Power ControlTo ensure reliable operation, the output power of the ZXD030 S480 rectifier varies with theAC input voltage and DC output voltage.

Power Control by AC Input

For the relation between the output power and the AC input voltage, see Figure 3-3.

l When the AC input voltage falls in the range of 165 VAC ~ 295 VAC, the maximumoutput power of the rectifier is 1740 W.

l When the AC input voltage falls in the range of 85 VAC ~ 165 VAC, the maximumoutput power of the rectifier varies linearly with the AC input voltage.

Figure 3-3 Output Power Versus AC Input Voltage

Power Control by DC Output

In the case of the AC input voltage falls in the range 165 VAC ~ 295 VAC with themaximum output power 1740 W provided, if the load keeps increasing, the output voltagewill decrease. And the maximum output power decreases consequently. For a detailedcurve, see Figure 3-4.

l When the output voltage falls in the range of 50 VDC ~ 58 VDC, the output power is1740 W. For example, when the DC output voltage is 58 VDC, the output current is30 A; when the DC output voltage is 58 VDC, the output current is 34.8 A.

l When the output voltage falls in the range of 40 VDC ~ 50 VDC, the rectifier providesa constant output current 34.5 A. And the maximum output power falls linearly withthe output voltage.

l When the output voltage falls down 40 VDC, the output voltage and current startflyback process.
