5.3 Mains Units NG 12/24 R and
NG 12/26 R
Use of a mains unit is recommended for filming in the studio
and when using electronic accessories with high power
consumption.
• First check that the correct mains voltage is set on the
mains unit.
• Ensure that the camera power is turned off.
• Set the voltage switch on the mains unit to 24/26 V.
• Plug the battery cable KC-20-S or the coiled battery
cable KC-29-S into the power supply socket on the
camera and into the 24/26 V socket on the mains unit.
Note: The NG 12/24 R was the original design that
provided 12 & 24 volts out – this was superseded
by the NG 12/26 R which outputs 12 & 26 volts.
The NG 12/24 R can easily be upgraded to
NG 12/26 R specification at an ARRI Service
Centre.
5.4 On-board Battery OBB-2
The OBB-2 On-Board Battery attaches directly to the camera
body by means of a quick change mechanism that can be
easily operated with one hand. The OBB-2 incorporates a
built-in power meter to indicate the state of charge, while
an extra contact in the power connector communicates this
and other information to the camera. When an OBB-2 is
connected, display Mode 3 offers the choice of showing
battery voltage (as normal) or battery capacity (in percent)
or an estimation of how many more magazines the remaining
charge can run. The OBB-2 is an intelligent 29.6 volt
Lithium-Ion battery with a capacity of 80 Watt/hours. A
fully charged OBB-2 will typically run seven magazines
and last about four hours in Standby. Although the 416
power connector has an additional contact it remains
compatible with standard ARRI 24 volt power cables.
The OBB-2 is for use with ARRIFLEX 416
cameras only.
Do not use with an extension cable as this will
prevent communication between the OBB-2 and
416. The 416 monitors the OBB-2 and prevents
it going into deep discharge.
