∵ Capable to work with constant-current, constant-resistance, 
   constant-voltage
   constant-power and combination of constant-current + constant-
   voltage,
   constant-resistance + constant-voltage mode      
∵ For transient switching operations, it is possible to set a slew rate
   (A/us)      
∵ Various circuit protection functions [overvoltage(OVP), overcurrent
   (OCP),
   overpower(OVP), overheat(OHP), undervoltage(UVP), Reverse
   connection(REV)
