Keywords: A800966, LU300b
Specifications:

Input Voltage: 90V to 360V

Output: 25A @ 12V (300W)

Efficiency @ 300W: 83% (max. heat loss is 51W)

Thermal Impedance (baseplate to ambient): 0.6oC/W

Operating Temperature Range: -20o (12oF) to 60oC (140oF)

Maximum Heatsink Temperature: 85oC (185oF)

Protection:

 - Output is short-circuit protected.

 - Input is reverse polarity protected

 - LU300b cuts out if baseplate temperature exceeds 85oC (185oF)

 - LU300b cuts out without damage, if input voltage is sustained at 365V to 400VDC

Series Connection: The LU300b can be connected in series to provide +24V @ 25A or +/- 12V @ 25A.

Mounting: Mount the LU300b on a solid metal frame to help dissipate heat generated at maximum output.
