• Solar / Alternative Power Systems
• Fuel Cells
The model VTC1000 Voltage Converter supplies 12V, 24V or 48 VDC
from a 110V, 220V or 300 VDC power source. Other input or output
voltages up to 360 volts are also available by special order.
The all-new Current Mode switching design offers increased power and
reliability in a compact package. Extra input and output filtering reduce
EMI to extremely low levels. Reliability features include an input fuse,
thermal shutdown, current limiting and short circuit shutdown with
automatic recovery.
The output voltage is easily adjusted 1.0 volts above or below the
standard output voltage to accommodate special requirements.
Optional features include a Remote Control, a Digital Volt Ammeter,
