VTC120i Series Manual

Introduction
The VTC120 Series Voltage Converter is a variable duty cycle switching power supply with
a precision linear regulator output except for the VTC120nr-12-24. It can be congured to
run from a 12 VDC or 24 VDC battery system to provide output voltages as shown below.
Depending on the version, the output is either Common Negative, or Fully Isolated from the
input. Three high output versions are also available.
Applications include running 24V PLC controls from a 12 Volt battery system, or any other
application requiring 24 VDC when only 12 VDC is available or to provide ground isolation
between two 12 VDC or 24 VDC power systems, or between a 12 VDC and 24 VDC power
system.
