The 71030i is a 25A DC-to-DC converter that can drive 30A loads intermittently. The converter is used to provide energy for 12V apparatus from battery systems whose nominal voltage is from
72V to 96V. The output is electrically isolated from the input.
The converter has two outputs. The outputs are called “unswitched” and “switched”. The
unswitched output provides power continuously when power is applied to the input. The switched output is controlled by an enable signal. The enable signal turns the switched output on and off.
The ENABLE input is referenced to the output side. Typically the ENABLE input would be
connected to the unswitched output through a key switch. If this switch is closed, then the
switched output turns on. If the switch is open, the switched output turns off.
The converter is designed to withstand reverse battery, over-temperature, over-current, and short circuit without damage to the unit.
The 71030i DC-DC Converter utilizes switching power supply technology.
The converter has protection from under-voltage and over-voltage on the input. If the input is too high or too low the converter will shut off to protect itself. Under-voltage protection incorporates a delay so that momentary battery sags do not turn off the converter.
The operating temperature of the converter is constantly monitored. If the unit becomes too hot, it will fold back to protect itself.
The converter uses current-mode control topology. This topology allows for cycle-by-cycle
current limiting during short circuits or overloads. |
