Specifications

Saminco Part Number A800966

Input Voltage: 90V to 360V

Output: 25A @ 12V (300W)

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

Thermal Impedance (baseplate to ambient): 0.6°C/W

Operating Temperature Range: -20°C (12°F) to 60°C (140°F)

Maximum Heatsink Temperature: 85°C (185°F)

Protection: -Output is short-circuit protected.
-Input is reverse polarity protected.
-LU300b cuts out if baseplate temperature exceeds 85°C (185°F).
-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.
