The model VTC615 Voltage Converter supplies either 12V, 24V, or 48 VDC from a 24V, 48V or 72VDC power source.
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, reverse battery hookup protection and output short circuit shutdown with automatic recovery.
The output voltage is easily adjusted 1.0 volts above or below the standard output voltage. Devices connected to the converter are protected by an output overvoltage crowbar circuit.
Optional features include a Remote Control, a 19 Rack Mount version, and/or a Digital Volt Ammeter to allow monitoring of output current and output voltage.
