The model VTC610 Voltage Converter supplies 12V, 24V or 48 VDC from a 110V or 250VDC power source. Other input/output voltages 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, Battery Charging and/or a 19 Rack Mount version.
