convection cooled models.
|
|
Line Regulation
|
±0.2% on main and auxiliary outputs
for ±1% on main output; 2% for load changes from
20-100% an auxiliary required on main output of WD300.
|
|

|
Overvoltage Protection
|
Overvoltage protection is provided
on the main 5 volt output only.
|
|
Overload Protection
|
A automatic electronic current
limiting circuit, limits the output current to a
preset value, thereby providing protection for the
load as well as the power supply.
