LFWLT100-CK metal cover kit accessory 

For Power supply unit with Base plate (metal accessory option) add “-B” suffix at the end of model number For Power supply unit with L bracket (metal accessory option) add “-L” suffix at the end of model number ~~For Power supply unit with U channel (metal accessory option) add “-U” suffx at the end of model number For Power supply unit with CK Cover kit (metal accessory option)  add “-CK” suffx at the end of model number~~ 

## Notes 

1. Combined output power from V1 and V FAN should not exceed the total output power rating. 

~~2. Ripple is 2% up to 20% load and < 1% above 20% load. Ripple is peak to peak with 20 MHz bandwidth and 10 µF (Electrolytic capacitor) in parallel with a 0.1 µF capacitor at rated line voltage and load ranges.~~ 

~~3. Fan output voltage tolerance is +/-20%.~~ 

~~4. Peak current for fan output is 1 A.~~ 

~~5. Class I products have an Earthing tab. Class II version available. Add “-II” suffx at the end of the Model Number to Order. Enquire with EOS Sales Rep before Order.~~ 

~~6. Specifcations are for nominal input voltage, 25~~ ° ~~C and max. load unless otherwise stated.~~ 

7. Derate output power linearly to 80% from 90 VAC to 80 VAC input. 

- 

- ~~8. When used in Cover Kit, de rate output power to 70 % under all operating conditions.~~

Stock Shortage Specialist

When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.

Compliant Alternatives

We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
