This is a critical question that is no easy to get a clear answer to when you have 15 Watt heating element sucking on the same cable as a 2 Watt light. So, we cheat! All Lopolight ice-class lights run a 5 second cyclus, where the heating is on for 4 seconds (if needed) and the heating shuts out for 1 second.
The Lopolight NLC has a number of monitoring relays, who have an ice-class feature, if this is activated the monitoring will happen over intervals of 5 seconds, when the monitoring relay in this period sees a power consumption that equals the expected value, then all is good. If not, the alarm is raised.
The other difference between a NLC for ice-class lights and regular Lopolights is the size of the power supplies.
