This sensibly priced four-channel controller allows you to connect and control output to four individual heater strips (not included). Most heater straps from all the major manufacturers are supported via standard RCA phono type sockets.
Total power output up to 8 amps. You will need to ensure that your power supply can deliver enough power for your requirements keeping in mind other equipment such as your mount and cameras also require power.
Each output can be set independently to the required output level. A cigarette-lighter type plug with a 10 amp fuse and 2m of cable is included.
