OMHAC415-100  

 
INTRODUCTION 

 

 
The   load   bank   HAC415-100    is   designed   for   testing   415   volt,   three   phase,   50   Hz  
UPS   or   generators   on   a   4   wire,   star,   connection,   plus   earth.   
The   load   bank   can   also   test   240   volt,   single   phase   supplies.  
 
The    user   features    of   this   load   bank   includes  
 

● The   unit   comprises   of   pre-set,   force   cooled,   high   powered   resistor   channels  

which   allows   manual   adjustment   of   the   load   current   via   a   hand   held   controller  

 

● Safety   features   include:  

○ internal   fuse   protection  
○ fan   motor   overload   protection  
○ auxiliary   circuit   protection  
○ auto   shutoff   in   the   event   of   a   mains   interruption  

 

● The   load   bank   is   force   cooled   by   a   single   phase   powered   fan   which   is  

connected   to   the   load   circuit   under   test.   

 

● The   case   is   designed   for   outdoor   use.
