Output power:
8600 W for all models
Efficiency:
91% for all models
Specs of version 54 and 55 only:
The connector #7 has been added, on version 54/55 only, to
power the control section of the psu, in order to have the latter
separated from main line power (provided through Conn #1)
The Conn #7 powers the remote head (fan, filament transfor-
mer, lamp) and the internal fan of the psu.
The user must provide an external switch to power/unpower
the control section of the SM1180 vers. 54/55.
Two 6A fuses (F1 and F2) are provided to protect the 230V
(nominal) circuit.
A max current of 1.4 Arms (@ 230V) must be provided in
normal operation, while 3.2 Arms is the max surge inrush
current, due to initial cold filament heating, every time the
filament is switched off (i.e. by removing the power input, or
by interlock chain opening).
The main line voltage can still be switched ON and OFF
through the front panel breaker.
WARNING: to avoid alarms it must be adopted the correct
sequence of switch-on
Enable signal
ON
OFF
Power section
ON
OFF
Control section
ON
OFF
Correct sequence:
1) Enable signal:
OFF
2) Control section:
POWER-ON
3) Preheating time:
30 seconds
4) Power section:
POWER-ON
5) Enable signal:
ON
No problem arises if the Power section is switched Off (or
ON) while the Enable signal is OFF, but powering down the
Power section while Enable is ONleads to A_4 alarm, after
10 seconds, as the system doesn’t sense the power anode
current.
Also powering ON together the Power section and the
Enable can cause an A_2 alarm
