OPTIONS 

FB800

The fuseboard FB800 provides 8 fused outputs, it is connected to one of the 27V outputs of the PSU830. On the 

cover of the PSU830 there are four M3 tapped holes to 

accept the male/female threaded pillars supplied with the 

FB800. 

PTM800 

The PTM800 provides screw terminals for 40V, 27V and 

5V supplies, necessary when second PSU830 is used to 

supply loop power to XLM800s. The 5V, 27V and 40V outputs are not fuse protected. The PTM800 is connected to 

the PSU830 via 12 way cable assembly. It is mounted by 

four plastic pillars and two 5/8 inch 4/40 UNC screws supplied with the PTM800. The PTM800 may be mounted 

on top or on the left hand side of the PSU830.
