The WSU120-1000-R is a 2VDC/12W 1-output wall plug-in Power Supply decrease product design time. This plug-in power source eliminates the need for internal power supply cooling devices, thereby reducing the noise level, size and weight of the end product. In addition, these compact power sources keep heat away from sensitive circuits and supply a safer lower output to the end product. Wall plug-in sources are completely enclosed to prevent tampering. They are offered in a wide range of popular voltages, power levels and reversed polarity (-R). They output voltage is regulated, which means the output voltage will not vary much with load. Models are available with generous six foot cord lengths and 50 to 60Hz operating frequency.
