CSF250EI Lambda Electronics, CSF250EI Datasheet - Page 3

• Manufacturer Part Number: CSF250EI
• Description: Sirius 250
• Manufacturer: Lambda Electronics

Notes:
Sirius Datasheet - Document Number 69652 - Rev 2.0 April 06
Ensure that the no more than 2 modules are selected.For example:-
With our Sirius range of power supplies, it possible to achieve many combinations of Volts and Amps. For the optimum configu-
ration, please contact our sales office. However you can also create your own configuration from this datasheet by using the
guide below.
Configuring from Datasheet
1 Select main outputs 1 and 2 from table on page 2. Calculate total output power to determine CS250 of CSF350 then select
2 Select Output Modules and Options from the Output Voltages tables.

required Cooling and Leakage Current from the following table:-
Example - if you require 5.2V / 12A on a CSF350 : -
Contact Lambda to validate configuration and issue a part number.
CSF350EI5/12 3.3L 5/12E
a - all module outputs are isolated
b - will allow 0.5V remote sense (total line drop), but will not adjust above specified range
c - values for ‘Amps’ in brackets are peak values
d - D module outputs have common 0V
Output 1 = 5V / 50A
Output 2 = 12V / 12A
Output 3 = 3.3V / 16A (24A peak)
Output 4 = 5V / 6A (9A peak)
Output 5 = 12V / 4.5A (6.75A peak)
