2.6[2.3] G) If the module with heatsink (CV) is used in free air. EXAMPLE 1: An DC1-24S module has an efficiency of 81%. What is themaximum ambient temperature if 100 Watts of power is needed? A) In free air: From Table 1: Trca = 4.8 Using relation (2) AT = 4.8 (100) =112.6°C B) In free air with heatsink (CV): T rca =3.3 AT = 3.3 (100)[-gpj— -l] =77.4°C Ta = 85 - 77.4 = 7.6C EXAMPLE 2: What would be the maximum output power for an DC1-24S module at an ambient temperature of 50°C with an efficiency of 81%? A) If the module is used in free air. From Table 1: Trca = 4.9 Using Relation (2): 85...

With local sense, Vout is regulated at 12V So, Vout = 12V Vload = Vout -Vwire1 - Vwire2 Vload = 12V - .2V - .2V With remote sense, Vload is regulated at 12V So, Vload = 12 V Vout = Vload + Vwire + Vwire2 Vout = 12V +.2V + .2V = 12.4 Volts The voltage drops in the wires connecting the +V and -V output terminals of the unit and the load depend on the size of the wire )or pcboard trace) and the current flowing through them.
