The Tandem-70 from Anton/Bauer offers a new approach to portable power. It combines all the functionality of a one-position InterActive charger with the convenience of a noise-free, camera-mounted, wide-range AC mains adapter. The Tandem-70 will power even the most power-hungry high-definition camera from any worldwide AC source. It also doubles as a full-function InterActive Charger, charging any Anton/Bauer Gold mount battery in two hours or less. Weighing only 1 lb, the Tandem-70 is the perfect addition to any field camera as a lightweight mains adapter and/or a high-performance charger. It meets all applicable regulatory requirements, including CE and FCC.

As with all Anton/Bauer chargers, charging with the Tandem-70 is fully automatic. Mount any Logic Series battery on the Tandem-70, and it will automatically determine the appropriate charge routine and execute it. The Tandem-70 will charge any Anton/Bauer Logic Series Gold mount battery, including:

• ProPac 14
• Digital ProPac 14
• TrimPac 14
• Digital Trimpac
• Hytron 50/100/140
• Dionic 90/160

The Tandem-70 incorporates the exclusive InterActive communication between the battery and charger, which allows the charger to identify any Anton/Bauer battery attached and determine the precise charge routine for that particular battery under its present condition.

In general, the Tandem-70 utilizes a three-stage charge routine for each battery.

The Tandem-70 will automatically operate as an AC adapter once the camera or other device is switched on. An on/off switch is not incorporated into the power supply (a green LED will light, indicating that the unit is operating as a power supply).

If the AC line voltage is removed and a charged battery is mounted on the Tandem-70, power from the battery will be routed to the camera. When the AC line voltage is restored, the battery is reevaluated for a proper charge routine.
