Over-Temperature Shutdown ( Without heat spreader)
Refer to Figure 19 for Hot spot 1 location
(48Vin,80% Io, 200LFM,Airflow from Vin+ to Vin-)
Over-Temperature Shutdown (With heat spreader)
Refer to Figure 22 for Hot spot 2 location
(48Vin,80% Io, 200LFM,Airflow from Vin+ to Vin-)
Over-Temperature Shutdown ( NTC resistor )
Refer to Figure 19 for NTC resistor location
Note: Please attach thermocouple on NTC resistor to test OTP function, the hot spots’ temperature is just for reference.
Note1: For applications with higher output capacitive load, please contact Delta
Note2: Trim down range -10% for 18Vin ~75Vin, Trim up range +10% for 20Vin ~ 75Vin.
