DC/DC Voltage Converters
VTC310 Isolated Series Voltage Converter
The model VTC310 Voltage Converter supplies 12V, 24V or 48 VDC from
a 110V, 220V or 300 VDC power source. Other 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.
Available options include a Remote Control and/or a Digital Volt Ammeter.
