1.3 

Power and Current Limit 

The rectifier automatically limits its output as load demand reaches it maximum capacity.  
 

1.4 

Output Over-Voltage Shut Down 

The rectifier will automatically shutdown if the output voltage exceeds the preset value. The Over Voltage 
Shut Down point reduces by about 1V at full load to ensure the rectifier producing the Over Voltage Shut 
Down turns off first. The Over Voltage Shutdown voltage is preset in the factory but may be adjusted. 

1.5 

Input Over/Under Voltage Shut Down 

If the input voltage is outside the specified range, the rectifier may shut down until the voltage returns 
within the specified range.  

1.6 

Rectifier Soft Start and Inrush Current 

On start-up, the peak mains inrush current is limited to twice the maximum operating current. The output 
voltage and current will rise slowly from zero during start-up.  This means that the AC input power slowly 
increases over a 2 second period, providing a gentle load characteristic for any standby generators. 

1.7 

Over Temperature Turn Down/Shutdown  

When the rectifier reaches its maximum operating temperature (internal), the rectifier will progressively 
reduce the output current to attempt to reduce the heat within the unit. In extreme circumstances, the 
rectifier internal temperature may continue to rise even with reduced output current.  In this case the 
rectifier will totally shutdown and will restart when the internal temperature returns within limits. 

The maximum ambient operating temperature range at full power is: -10 to 50 ºC. 

The rectifier will operate in ambient temperatures up to 70ºC but the rectifier will de-rate its output power to 
keep internal temperatures within the allowable range. 

1.8 

Reverse Polarity Protection  

The rectifier has an internal reverse polarity protection fuse and crowbar diode fitted. These parts are not 
user serviceable, and the rectifier will require returning for servicing if incorrect polarity is applied to the 
output. 

1.9 

Active Load Share 

The rectifier will actively current share with other rectifiers in the same DC system.  The rectifiers are 
interconnected through pin 11 of their connector.  The hardware in each rectifier looks at this current share 
bus and adjusts its output current to align with other rectifiers.  In addition to this control, the monitor can 
compare rectifier output currents and adjust individual rectifiers to achieve current share.  The rectifier 
current share bus is generally used within one rack of rectifiers and the monitor control is used to make 
separate racks share with each other. 

1.10 Fan 

Cooling 

The rectifier constantly monitors its internal temperature, ambient temperature and output current, then 
adjusts fan speed to ensure continued operation.  This control of fan speed ensures that rectifier acoustic 
noise and dust accumulation are minimized. 

If the fan fails and cannot be restarted then the current limit will further reduce to 10A.  The rectifier will 
continue to operate as long as the internal temperature stays within allowable limits. 

1.11 

Serial Alarm and Control Interface 

The rectifier, when installed in a Newmar C2RS rectifier shelf, is controlled via the serial interface by the 
system monitor.  The system monitor can set up control parameters and receive alarm information via this 
interface. 

If this interface is disconnected or fails for some reason the rectifier will operate with the parameters last 
sent from the monitor.  Current share will revert to the rectifier current share bus.
