4.4. Operating Profile

With its combination of resistor and linear elements, the ALx Series MagnaLOAD has a unique operating profile as indicated in the figures below. Three different profiles are provided, depending on the model’s maxium voltage rating. The profiles are normalized about the model’s maximum voltage, current, and power ratings.

Fig. 4.5 Normalized ALx Series Operating Profile for 200 Vdc Models

Fig. 4.6 Normalized ALx Series Operating Profile for 500 Vdc Models

Fig. 4.7 Normalized ALx Series Operating Profile for 1000 Vdc Models

In the event the user programs the unit to operate in region outside the operating curve, the MagnaLOAD electronic load will automatically limit its throughput to prevent any possible damage. This internal limiting will be indicated on the front panel auxiliary display, on the message line as: Operating profile limit reached.
