I have one of these on my track it says the following
Protects against power surges ( which it did)
Protects against power spikes ( which it did or must of)
Special duplex Electronics
Bi-Directional Duplexed
Any way heres my problem I have burnt out 2 of these first one I feel was because a train car jumped the track and ark and everything went dead okay my fault there track wasn’t aligned correctly. second one no idea was running train stopped as engine and b unit separated so unplug power and put all back right plugged power cord in second one was fried no idea
now heres what I’m wondering am I pulling to much current thru it as I have 2 A units with dual motors 2 B units with tmcc in them one has rail sounds 7 mth passenger cars with 5 bulbs in each oh all A units and B units have lights in them also
I’m using a ZW to run this 14’ x 16’ loop of track ( post war zw 275 watts per the plate on the casing) but have it set at only 14 volts coming out .
please reply in simplest terms possible as not that electric knowledge here.
