The model VTC315 Voltage Converter supplies either 12V, 24V, or 48 VDC from a 24V or 48VDC 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.
Available options include a Remote Control and/or a Digital Volt Ammeter to monitor output current and voltage.
