Dolgin Debuts 4-Slot Smart Battery Charger
February 25, 2006
Lexington, MA - Dolgin Engineering has introduced the TC400, a 4-position microprocessor-based 7.2v battery charger ($495-$695).
Designed for video production studios and rental facilities, the unit is designed to provide fast, reliable charging of multiple camera batteries for both in-house and field use.
The charger also functions as a battery tester, and can power a camera using a worldwide 100-240v AC or 12v DC power source.
According to company president Alex Dolgin, who designed the charger, the TC400 incorporates a host of key features including:
-- Fast, safe simultaneous charging of any common 7.2v (Sony, Panasonic, JVC, Canon) packs.
-- Digital LCD display accurately indicates the battery pack charge in progress status and true capacity upon charge completion.
-- Each of the 4 channels is fully independent of the others.
-- Built-in Battery Test/Discharge Module cycles the battery pack and reports true pack capacity as tested.
-- DC output for camera operation from AC mains or a 12v DC power source.
-- Sleek, small and lightweight package.
The TC400 also features a highly-efficient smart charging circuit. “It takes only about 3.5 hours to charge a typical high capacity battery pack. The pack can be left on the charger after the charge is complete,” said Dolgin.
The design of the charger he said, is based on modern “gas gauge” technology, which allows direct monitoring of the battery’s capacity. The multifunction LCD display with backlight shows charge-in-progress data, including voltage, estimated percent of readiness, and the actual amount of charge in mAh input to the battery after the battery’s insertion.
Due to its modular design and software-based functionality, the TC400 can provide flexibility for various video applications. Several expansion options are also available including:
·Test/discharge circuit for complete battery characterization.
·Camera power 7.2v.
·12v DC power for mobile use, using cigarette lighter car cord for connection to the power source.
