3.5.4 Over Temperature Protection (OTP)
SLM-Series AC/DC Electronic load is provided with a temperature sensor. Over
temperature protection (OTP) is tripped when the heat dissipater temperature
exceeds about 85ºC ±5ºC, and the lower DM flashes “oTP”. Once the over
temperature condition is reset, the lower DM resumes normal display.
When OTP occurs, check the ambient working temperature and ventilation. The air
outlet on requires a distance of greater than 6 in / 15 cm from any obstruction, for
proper ventilation.
