I have a case where an elecctronic timer with a neutral which switches a re lay as well as an X10 relay switch with neutral isn't working to switch a 1
50 watt LED (not 150 W "equivalent" but an actual 1.25 amp 150 watt load). They will switch the relay and turn the light ON but it drops out shortly a ftwerwards.
The timer worked fine with a 100 watt LED but refused when I replaced it wi th the 150Watt flood. Timer is rated for 1800 watts and even 8 amps reacti ve load.
The only explanation seems to be the distorted waveform caused by the nonli near switching supplies (3 in the 150 watt light but 2 in the 100 watt) cau ses the timer circuitry to drop the relay. I am trying to find out the THD and/or power fafctor of this light and also hope to look at the current an d voltage waveforms on a scope soon. It is a VERY odd problem!
