We have experienced some temperature problems with other makes of power conditioners. Has SolaHD addressed this problem?
A. SolaHD’s ferroresonant power conditioners are very stable with respect to temperature. The change in output voltage is only 0.025% per degree centigrade. Units are factory adjusted to +2%/-0% of nominal, with full load and nominal input voltage. This adjustment to the high side of nominal is to compensate for the natural temperature drift of about 1% that takes place during initial turn on or warm up. When the unit warms up to operating temperature, the voltage typically falls about 1%. This is why no load “cold steel” voltage measurements may be slightly on the high side. At a stable operating temperature, the output voltage will change slightly with varying ambient temperatures. This shift is equal to approximately 1% for each 40oC of temperature change. The normal maximum temperature rise of a SolaHD power conditioner may fall anywhere in the range of 40oC to 110oC depending on the type and rating. The nominal design ambient rage is between -20oC and +50oC. (-20oC to +40oC for 70
