Taxi Radio Booster Model 670 DC Converter

12 VDC to 16 VDC at 70 amps continuous

The Taxi Radio Booster Model 670 DC Converter by SEC America is a US built 1000 watt unit, of the highest quality. The SEC unit is highly efficient, which provides cool operation, high reliability, and long life expectancy for the converter and the equipment which it powers. The design makes this performance possible over an extremely wide operating temperature range(the best we have seen) and under the most rigorous vibration and shock conditions. Only top quality components are used. These units may cost more than others, but are fully suitable for military, industrial, scientific, and other applications where exceptional electronics are demanded. There are a number of these units in cabs in New York.

The Model 670 will boost voltage in 12V vehicles to levels between 15V and 18V, enabling the operation of communication equipment at full capacity. While Model 670 derives its input from the auto's electrical system, its output may be connected to power only the transceiver. This approach avoids degradation in the remainder of the vehicle’s electrical components that would occur from a boost in the vehicle's overall electrical voltage. When the booster is in the off state it simply feeds its input voltage to its load unboosted.
