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: 

|_Ambient Temperature (°C)_|-20|-25|-30|-35|-40|
|---|---|---|---|---|---|
|_Recommended External Capacitors (μF)_|1000|2200|3300|12000|22000|



4. 48 V: 1% limit is achieved with 3X 470 uF/63 V external cap. Otherwise, maximum limits are 1.5% max at Ta ≥ 0 °C and 2% max at Ta < 0 °C. 

5. Safety Approvals: China CCC approval applies to part numbers with “-xxE” suffixes only. 

6. 12 V unit requires external filtering for MIL-STD-461E compliance. Consult Artesyn Technical Support. 

7. Warranty: 2 years
