NASN rectifiers  

NASN rectifiers bring advanced technology to the DC power industry. Innovative engineering combines the best in efficiency and reliability to meet the power requirements for a variety of system applications. This rectifier is specifically designed to recharge all types of stationary batteries for large utility, petrochemical and industrial uses.

The fan cooled rectifier module has extremely high density providing the most power in the least amount of space. A compact shelf accommodates four rectifiers per 19inch 1U shelf and can be paralleled up to 5*1U 19inch shelf.

Local and remote setup, adjustment and control is a simple, single-step process with the rectifier System Controller. By utilizing TCP/IP technology, complete configuration and monitoring of power equipment is possible through a Windows Internet Explorer browser.

We can provide turnkey solutions for outside plant, headend, telecommunications, industrial and renewable energy applications. We work to combine your small-, medium- and large-scale projects with the necessary installation resources.

DC Input Characteristics
 
1.2 Output Characteristics
1.2.1 Output voltage & current regulation
1.2.2 Output Ripple & Noise
 
Note: 1) ripple & noise test: ripple& noise bandwidth is set at 20 MHz.

1.2.3 Output Transient Response
  Note: the load jump period is 4ms.

1.2.4 Startup Output Overshoot
  1.2.5 Startup Delay
  Note: startup delay starts from power on to output voltage rising up to 42VDC.

1.2.6 Power Conversion Point(53.5V)
 
1.2.7 Output External Characteristic


1.2.8 Temperature Derating
 


1.2.9 Noise Voltage
 
1.3 Protection Function
1.3.1 Output Short Circuit Protection 1.3.2 Output Over-voltage Protection
Output over voltage protection can be divided into the internal over voltage protection and the external counterpart. Internal overvoltage fault range is 58.5VDC~60.5 VDC, which can be set through monitoring; when failure occurs, the module is locked. The external voltage is greater than 63VDC and lasts more than 500ms, the module is locked. Being in the protection state, the AC power supply shall be disconnected first and then reenergized to ensure the power supply resumes work properly.
1.3.3 Output Under-voltage Alarm
The input under-voltage range is 37VDC~39VDC. When the input voltage is lower than the under-voltage alarm value, alarm prompt will be reported with normal output.
1.3.4 Input Over-voltage Alarm & Protection
AC Input

DC Input Note: input over-voltage protection shall be tested with 50A rated load.
1.3.5 Input Under-voltage Alarm & Protection
AC Input DC Input 1.3.6 Over-temperature Protection 1.4 Communication between Rectifier Module & Monitoring Module 
CAN-bus communication mode is adopted between the rectifier module and the monitoring module. Remote software version upgrade is supported, and the address of the module can be set through the address board. When AC input is disconnected, the module needs to communicate with the host.
Isolation design is employed for CAN interface in the rectifier module. The power supply of CAN is +5Vdc, which is provided by the rectifier module internally.
The main monitoring information of the rectifier module is as below:
1) Voltage regulation & current regulation functions: meeting the requirements of floating charging battery and voltage regulation;
2) Single module control of startup & shutdown;
3) Protection & Alarm Information Feedback:
Mains fault: mains fault (AC input over-voltage/under-voltage);
Module protection: temperature pre-alarm;
Module fault: fan fault, over temperature shutdown or no output caused by the module internally;(the module is in the state of dormancy and shutdown, and the mains failure is not reported to the module).
