5.3Mains Units NG 12/24 R and 5.4 On-board Battery OBB-2 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| provided 12 & 24 volts out – this was superseded |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. |
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.
