CB Certificate and report
This product is CE marked following
the provisions of the Low Voltage
Directive 73/23/EEC
Auxiliary Connections
1 Remote sense - 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 3 to pin 5
(common) will inhibit the outputs.
5 Remote Enable. To convert to enable, cut
jumper J1; connecting pin 4 to pin 5 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 6.3A 20mm Quick Acting HBC
mains fuse - only replace with same type
and rating to maintain safety standards.
