This product is CE marked following
the provisions of the Low Voltage
Directive 73/23/EEC
Auxiliary Connections
1 Remote sense -Main and 4th output - optional
connection- can compensate for up to 0.5V drop;
internal local sense connected if not used.
Protected against reverse connection.
2 AC Power Fail signal;-TTL compatible signal goes
high 50-150ms after switch on. Goes low >4 ms
before 5V drops to 4.75V.
3 DC Power OK:- TTL compatible signal goes high
at same time as AC Power Fail. Goes low when 5V
drops to 4.75V.
4 Remote Inhibit. Connecting pin 8 to pin 10
(common) will inhibit the outputs.
5 Remote Enable. To convert to enable, cut jumper
J1; connecting pin 9 to pin 10 will enable outputs.
6 Paralleling power supplies - when the 'C share'
signal is connected between two power supplies
the main 5V outputs will current share.
Fusing
Input fuse 10A 20mm Quick Acting HBC
mains fuse - only replace with same type
and rating to maintain safety standards.
