I had asked the question. "Is 277vac input ratio-metric to the 24vdc output? what is output voltage if use this model w/120vac voltage? will it trigger relay if less than 24dc?"
Real Answers now that i have purchased and tested the item.
The 277vac input line (the black wire) was supplied with single phase 120vac voltage 60hz.
My question was, "is it ratio-metric to the output" and the seller obviously didn't know what i was asking which is no big deal because i wanted to test the device anyway just for fun in the lab.
The DC output was 10.2Vdc when supplied with 120vac. 120/10.2= 11.76
The spec DC output says 24Vdc when supplied with 277Vac. 277/24=11.54
Both ratios are equal. IT IS RATIO-METRIC.
Could not find a clear sepc sheet on the product.
IMPORTANT: the 120vac input as stated above supplies a 10.2vdc output. This DC voltage is not enough to close relay coil and supply through current between the red high power wire. I used a boost regulator to up the DC voltage to find its trigger point. It is roughly 11.6Vdc.
