CAUTION

· The outputs less than 28V model has possibility that hazardous voltage may occur in output terminal depending on failure mode.
The output of these products must be protected in the end use equipment to maintain SELV.

· 48V output model are considered non-SELV. End equipment manufacturers must provide protection against inadvertent
contact by a service engineer.

· This information in this document is subject to change without prior notice. Please refer to the latest version of the data sheet,
etc., for the most up-to date specifications of the product.

· No part of this document may be copied or reproduced in any form without prior written consent TDK-Lambda.

F1 : External Input Fuse

PFE300SA,500SA Series has no internal fuse. Use external fuse to acquire each Safety Standard and to
further improve safety. PFE300SA,500SA Series acquired safety standard certification using 15A,
250V,Fast-Blow external fuse. Further, Fast-Blow type fuse must be used per one module. Also, in-rush
surge current flows during line throw-in. Be sure to check I2t rating of external switch and external fuse.

Recommended External Fuse：15A , 250V

Note) Select fuse based on rated voltage, rated current and surge current capability.

(1) Voltage Ratings

100VAC line : AC125V
200VAC line : AC250V

(2) Current Ratings

Rated current is determined by the maximum input current based on operating conditions and can be

calculated by the following formula.

For Efficiency and Power Factor values, refer to separate document “PFE300SA Series Evaluation Data”
or “PFE500SA Series Evaluation Data”.

C1, C4, C5 : 1uF (Film Capacitor)

Ripple current flows through this capacitor. When selecting capacitor, be sure to check the allowable
maximum ripple current rating of this capacitor. Verify the actual ripple current flowing through this
capacitor by doing actual measurement.
Connect C5 as close as possible towards the input terminals AC(N) and AC(L) of this power module.

Recommended Voltage Rating : 250VAC

L1, L2 : 6mH

Add common mode choke coil as EMI/EMS countermeasure. When using multiple modules, connect coil to
each module.

Note) Depending on the input filter used, noise might increase or power module might malfunction due to

C2, C3 : 4700pF(Ceramic Capacitor)

Add ceramic capacitor as EMI/EMS countermeasure. Be sure to consider leakage current of your equipment
when adding this capacitor.
High withstand voltage are applied across this capacitor depending on the application. Select capacitor with
high withstand voltage rating.
