The VTC180 Series of voltage converters are variable duty cycle
switching power supplies. They can be configured to run from a 24V,
32V, 48V or 72 VDC power systems to provide output voltages as
shown below.
The VTC180 Series Voltage Converter features reverse input
protection, current limiting, output over-voltage protection, ultra quiet
low EMI operation and a wide operating temperature range.
We are confident that you will get many years of reliable service from
this Voltage Converter.
