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 common 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.
