3.1 AC Input Over/Under-Voltage ProtectionFor the AC input over/under-voltage protection and power decrease control, refer to Table3-1 and see Figure 3-1.

Table 3-1 AC Input Over/Under-Voltage Protection and Power Control

AC Input Voltage Protection and Power Control

≤ 70 V Auxiliary power supply startup

≤ 80 V The post-DC/DC conversion circuit and the pre-PFC circuit stop working.

110 V - 150 V Current limit Imax = (20 ± 2) A

150 V - 300 V Current limit Imax = (32 ± 1) A

≥ 300 V The post-DC/DC conversion circuit and the pre-PFC circuit stop working.

3-1



Figure 3-1 AC Input Over/Under-Voltage Protection

l The protection function is implemented through hardware.l The precision of the voltage is ± 10 V and the hysteresis width is (15 ± 10) V.

3.2 PFC Output Over/Under-Voltage ProtectionThe PFC output over/under-voltage protection is as follows:

l When the PFC output voltage > 440 V DC, the post-DC/DC conversion circuit and thepre-PFC circuit stop working.

l When the PFC output voltage < 340 V DC, the post-DC/DC conversion circuit stopsworking.

The PFC output over/under-voltage protection is implemented through hardware. Theprecision of the voltage is ±10 V and the hysteresis width is (15 ± 10) V.

3.3 Output Over-Voltage ProtectionThe output over-voltage protection circuit prevents the DC output filter capacitor andpowered devices from damage due to voltage loop failure.

The output over-voltage protection threshold is (61 ± 1) V, which is unmodifiable. Whenthe output voltage exceeds (61 ± 1) V, the rectifier disables output and will not enable ituntil the fault is eliminated after power-off and the rectifier is restarted.

3-2


Chapter 3 ZXD1500 (V4.0) Rectifier Specifications

3.4 Output Over-Current ProtectionThe output over-current protection circuit prevents the rectifier from being damaged dueto the fault of output current limit circuit.

To avoid over-current protection prior to current limit protection, the response ofover-current protection is set to be slower than current limit protection, and the over-currentprotection threshold is set to be higher than the maximum current limit threshold.

The over-current protection threshold of the rectifier is (36 ± 2) A.

The output over-current protection is a kind of backup protection and is configured as"unrecoverable". It does not act generally; however, once the over-current protectionis activated, the function will not recover until the fault is eliminated and the rectifier isrestarted.

3.5 Over-Temperature Protection and Fan SpeedControl

According to the temperature of the radiator, the fan may work at full speed or half speed.

l When the temperature is over 50 °C, the fan works at full speed.l When the temperature is below 50 °C, the fan works at half speed.

The radiator temperature may keep increasing when the fan is faulty or it is working atfull speed. Therefore, a negative temperature coefficient thermistor is used to prevent therectifier from being damaged due to over-temperature. The over-temperature protectionis as follows:

l When the temperature exceeds the temperature protection threshold, the post-DC/DCconversion circuit stops working.

l When the temperature is below the temperature protection threshold, the post-DC/DCconversion circuit starts to work.

Appendix AAlarm ListTable A-1 lists the alarms that can be detected by the B121-CSU (SV2.20) supervisionunit, and describes their default alarm levels and output relays.

l A1 - A5 refer to 5 output relays for the alarms.l Multiple alarms can share one output relay. Each alarm cannot correspond to multiple

output relays but one output relay only. “0” means that no output relay is assignedto an alarm. When an alarm is reported, it indicates that problems occur on thecorresponding output relay.

l Except for “Total Alarm” and “Start GEN”, the output relay of an alarm will not takeeffect when its alarm level is set to “Mask”.
