ambient conditions
Notes (refer to table)
1. Peak current lasting < 30 seconds with a maximum 10% duty cycle.
2. At 25°C including initial tolerance, line voltage, load currents and output
n.
voltages adjusted to factory settings.
3. Peak-to-peak with 20 MHz bandwidth and 10 µF in parallel with a 0.1 µF
capacitor.
4. Output voltage user adjustable over range shown. Factory set at nominal
voltage.
5. Minimum load required for regulation, Unit will operate at no load but over
voltage protection may latch.
6. Continuous maximum power drawn must not exceed 250W with fan cooling.
Not to be used without cooling fan.

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.
