7. load over all channels is recommended as it will minimize problems caused by voltage drops and long cable runs Using cable with heavy gauge power wires can also reduce problems If erratic behavior is noticed on a channel try reducing the load on that channel and make sure that it is properly terminated An example system using the PSU 200 The design calls for 20 Wybron Forerunners OW each Since this is a maximum load of 200W it is compatible with the PSU 200 Ideally there would 5 on each channel an even distribution of 40W per channel but 10 a channel or even 20 on one channel would be acceptable as long as the cable run is relatively short An example system using the PSU 400 The design calls for 16 Rosco I Cues 1 7W each 16 DHA Double Indexing Rotators 6W each This is a total load of 368W which is compatible with the PSU 400 However this exceeds the 200W limit on channels amp 2 or 3 amp 4 so the load must be split between at least two channels The ideal would be 4 of each accessory on each channel which is 92W per channel and 84W per channel pair under the 200W limit Alternatively there could be 8 of each accessory on channels and 3 keeping the 184W per channel pair Again this is not recommended for long cable runs Mounting and Installation PSU 200 The PSU 200 can be hung from any C clamp or other mounting device that uses _ bolt The three holes on the handle of
