Introduction
All new Current Mode switching design offers increased power and reliability in a compact
package. Extra input and output ltering 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. An output overvoltage
crowbar circuit protects devices connected to the converter. The model VTC1015 Voltage
Converter supplies either 12, 24, 32 or 48 VDC from a 24, 48, or 72 VDC power source. Other
input voltages up to 72 volts or output voltages up to 48 volts are also available by special
order. High quality digital meters can be added (factory option) to allow monitoring of output
current and output voltage.
