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). This model is co mmon
negative. This means that the input negative (ground) connection
and the output negative (ground) connection are common or tied
together.
Applications include running 24V PLC controls or electronic
equipment from a 12 Volt battery system, or any other application
requiring 24 VDC when only 12 VDC is available.
We are confident that you will get many years of reliable service
from this Voltage Converter.
