Power Supply Requirements
The
UltraTWIN
can operate from AC supply or from a DC battery and is
designed for use in temperatures between -4
o
F to +140
o
F (-20
o
C to +50
o
C).
The
AC
is
115 +5% / -10% 50/60Hz
. The
DC
is
18-30V
. In all cases the
UltraTWIN
will typically consume 6W of power, with a maximum of 10W. If
UltraTWIN
has both an AC and DC supply available then the AC supply
source will be automatically sensed and used, should the AC supply be
removed for any reason then the DC supply will take over.
The AC and DC wiring should be completed using either 16
–
14AWG (1.5
–
2.5mm
2
) stranded or 16
–
14AWG (1.5
–
4mm
2
) solid wire, with all terminals
being tightened to 4.5in. lbs. (0.5Nm). An external supply isolator/circuit
breaker (AC or DC) must be fitted near to the unit and labelled to identify
the instrument to which it refers.
Important Information
All shipping cartons should be opened carefully. When using a box cutter, do not
plunge the blade deeply into the box, as it could potentially cut or scratch
equipment components. Carefully remove equipment from each carton,
checking it against the packing list before discarding any packing material. If
there is any shortage or obvious shipping damage to the equipment, report it
immediately to Pulsar Process Measurement Limited.
