To improve output voltage stability against power sag, switch mode power supplies often incorporate bulk capacitors, which reduce the ripple voltage to twice that of the output supply frequency.
MEAN WELL is world renowned for manufacturing highly reliable power supplies. However, occasionally there are field failures and if you purchased from an offshore company... What happens next can be a problem.
Since MEAN WELL introduced the RD, RID, RT, and RQ series multi-rail power supplies, they have become remarkably popular with OEMs around the world.
If you are experiencing difficulties with programming the MEAN WELL RPB-1600 and RCB-1600 series battery chargers, it could be due to a programmer software update.

In some of the MEAN WELL LED driver data sheets you will come across the description “Constant Voltage + Constant Current mode output”.
