Analytic Heavy Duty 40-60V In, 12V Out, 20A, Isolated DC/DC Converter VTC315-48-12
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.
