FIGURE 1.5 INPUT VOLTAGE/CURRENT/POWER RELATION DIAGRAM
The theory of the CP operation comes from the divider circuit built in the load. Because of the nonlinear
characteristic of the divider, the input voltage, input current, and power setting will limit the CP mode of operation.
The CP mode will not allow the load to operate beyond the full range of the Constant Power setting.
AIRFLOW FUNCTION
Airflow plays and important part in power dissipation. The programming electronic load uses cooling fans as a
standard cooling system for removing the heat generated from the power module.
Do not impede or obstruct the ventilation holes for any reason to prevent the power components from overheating.
All PEL’s have OTP protection to prevent the unit from overheating. The standard programming electronic loads
have forced air-cooling fans installed as the main cooling system and operate when the power-handling unit is turned
on.
