rickman 0 Posted May 28, 2015 Hi Is there anybody that could help I have a Pelco WCS1-4 and running 240v into the unit with a 500ma fuse which keeps blowing. 3 fuses have blow when power is run into the unit could the unit be faulty or am I doing something wrong.

jazzar 0 Posted June 10, 2015 is the 500ma the original fuse size on the 240v side of the psu ? if so then you probably have a faulty unit- maybe a short in the transformer winding on the mains side. With nothing connected on the low voltage side (camera side) you should be able to power up the unit without blowing the fuse. Share this post Link to post Share on other sites
