Rectifier 200I/48



NT5C05C   Installation and User Manual 

The rectifier monitors itself for high voltage and will shut down when its 
output voltage exceeds a preset adjustable value ( between -52 V and 
-60 V ). 

The rectifier monitors its operation and triggers a global RFA if it detects 
an internal failure, causing the RFA LED to light up. One of the following 
will trigger an alarm : 

• 

abnormal or out of range ac input voltage 

• 

output fuse failure 

• 

system or internal shutdown ( thermal, HVSD, TR ) 

• 

internal failure causing a power switching malfunction 

If the switching malfunction is caused by an improper adjustment of the 
output float voltage, the RFA alarm will not be triggered. The RFA feature 
will be activated if the ac power is removed in a system where batteries are 
present.

 

This LED lights up if the remote sense leads are not connected, or if the 
RC fuse has blown. 

This LED lights up when the rectifier is protecting itself against 
overheating by suspending its operation for the duration of the high 
temperature condition. An RFA alarm will also be triggered. 

The current and voltage calibration, adjustment and control can be set 
through potentiometers and switches ( see Table 11 ) located on the front 
panel, or by remote signals sent from the controller ( see Tables 8 and 12 ).
