SM 1280
Handling Warnings
The SM1280x has two handles on the front panel to help
unpacking and handling operations: never use only the
handles to lift the equipment but support the weight with
an appropriate base on bottom!
The handles do not withstand the off-center weight of the
equipment (35 kg = 77 lbs).
General Description
The SM1280x is able to supply the power required by a
magnetron type YJ1600 (National) or PM60 (Panasonic) or
H3881 (Hitachi) or E 3327 (Toshiba), with nominal power of
6 kW @ 2.45 GHz.
The output power can be adjusted continuously, from 10% up
to 100%, using an external analog signal from 1 to 10Vdc,
or by remote control, through filedbus interface or by front
panel commands, depending from model. The basic model
does not have any local command.
The unit, in addition to power the magnetron, has several
features and commands to control and power the magnetron’s
accessories.
The
SM1280x
has been developed to power and monitor our
remotable microwave head type TMx6x.
The
SM1280x
unit may also be used to power microwave
generators (heads) developed by others manufacturers under
condition that they are electrically compatible: moreover it is
mandatory to use our filament transformer FIL200 to guarantee
a proper filament reduction curve. See the electrical specifica
-
tions of the unit on the next pages.
The reduced height of the rack (only 7 HE, corresponding
to 310 mm) allows to use small cabinet, even in big plant:
i.e. in a standard cabinet with an height of 2 meters, arranged
to receive 19” racks, up to 5 SM1280x units may be easily
installed.
The user must provide a proper cooling flow: the cooling air
enter into the unit from the front side, it passes through the
internal circuits and components, then it goes out from the
back. The intake air flow is approx. 200 m
3
/h.
The SM1280 is designed to be an alternative of the existing
SM1180 serie, when is needed a network connectivity, not
available on the previous model.
The SM1280 is available in both European and Japanese/US
voltages.
The SM1280 carries new features mainly driven by the new
CPU core and is offered in 6 versions:
- “
Basic” version (vers. 0)
has only one RS 232 standard port,
which allows to drive/manage the unit with a simple software
(like our “Front Panel” package distributed freely).
-
“Bus” version (vers. 1)
which implements an industrial bus
interface like Modbus/TCP or Profibus or ProfiNET, etc.,
allowing connection of multiple devices on the same bus.
-
”Display” version (vers. 2)
includes front panel commands
and LCD display as well as the features of the basic version.
- “
Aux IN
” version (
vers. 50-51
) has a separate connector
for input of Auxiliary voltage which allows to manage safety
shut-down of main power but keeping alive the unit’s CPU.
The vers. 51 has the same configuration with the fieldbus
connector.
- “
Legacy
SM1180” version (
vers. 22
) is a full replacement
for installation that uses the former SM1180, except minor
changes. See relevant chapter.
