l
A wide range of input phase voltage (80 VAC - 300 VAC) makes the system suitable
for areas with unstable voltage.
Integrating the power distribution, rectifiers, CSU and batteries in a single cabinet, and
thus saving installation space.
The rectifier is hot-pluggable, and convenient for installation and maintenance.
Intelligent CSU.
With heat exchanger and Thermoelectric Cooler (TEC) for heat dissipation.
High reliability with Mean Time Between Failures (MTBF) ≥ 2.2 × 105 h.
Multiple networking interfaces: input relays, output relays, RS232 interfaces, and
RS485 interface.

The protection function is implemented through hardware.
The precision of the voltage is ± 10 V and the hysteresis width is (15 ± 10) V.
3.2.2 PFC Output Over/Under-Voltage Protection
The PFC output over/under-voltage protection is as follows:
l
l
When the PFC output voltage > 440 VDC, the post-DC/DC conversion circuit and the
pre-PFC circuit stop working.
When the PFC output voltage < 340 VDC, the post-DC/DC conversion circuit stops
working.
The PFC output over/under-voltage protection is implemented through hardware. The
precision of the voltage is ±10 V and the hysteresis width is (15 ± 10) V.
3.2.3 Output Over-Voltage Protection
The output over-voltage protection circuit prevents the DC output filter capacitor and
powered devices from damage due to voltage loop failure.
The output over-voltage protection threshold is (61 ± 1) V, which is unmodifiable. When
the output voltage exceeds (61 ± 1) V, the rectifier disables output and will not enable it
until the fault is eliminated after power-off and the rectifier is restarted.

Chapter 3 ZXD1500 Rectifier Specifications
3.2.4 Output Over-Current Protection
The output over-current protection circuit prevents the rectifier from being damaged due
to the fault of output current limit circuit.
To avoid over-current protection prior to current limit protection, the response of
over-current protection is set to be slower than current limit protection, and the over-current
protection 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 protection
is activated, the function will not recover until the fault is eliminated and the rectifier is
restarted.
3.2.5 Over-Temperature Protection and Fan Speed Control
According to the temperature of the radiator, the fan may work at full speed or half speed.
l
l
When the temperature is over 50 °C, the fan works at full speed.
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 at
full speed. Therefore, a negative temperature coefficient thermistor is used to prevent the
rectifier from being damaged due to over-temperature. The over-temperature protection
is as follows:
l
l
When the temperature exceeds the temperature protection threshold, the post-DC/DC
conversion circuit stops working.
When the temperature is below the temperature protection threshold, the post-DC/DC
conversion circuit starts to work.
