1. Output ripple measured at the end of the output cable terminated with 10 μF tantalum cap in parallel with 0.1 μF ceramic capacitor.
2. 12 V: 1% limit is achieved with 2X 820 uF/16 V external cap (e.g. PLG1C821MDO1 from Nichicon or equivalent). Otherwise, maximum
limits are 1.5% at Ta ≥ 0 °C and 2.0% max at Ta < 0 °C.
3. 24 V: 1% limit is achieved with 2X 820 uF/35 V external cap (e.g. UPM1V821MHD1TO from Nichicon or equivalent). Otherwise,
maximum limits are 1.5% at Ta ≥ -10 °C. 2.0% max ripple at Ta < -10 °C is met with below external capacitance:

5. Two (2) LCC250 model numbers exist with same electrical performance except for safety approvals as shown below:
• LCC250-XXu-xPE version = Europe/China safety approved & carries CE/TÜV & CCC logos
• LCC250-XXu-xP version = Europe/USA safety approved & carries CE/TÜV & cUL logos
6. 12 V unit requires external filtering for MIL-STD-461E compliance. Consult Artesyn Technical Support.
