OVP, OCP AND UVP FUNCTIONS

current, and duration settings of the sequence. The shortest time

for each step is 50ms and the maximum steps are 1000. The

sequence function is to test DUT's response to the fast changing

power supply that is one of the crucial verification items for

electronic products' reliability tests.

PRESET FUNCTION

The PLR-series provides three parameter preset function keys on

the front panel and each preset memory consists of parameters of

output voltage and output current settings. Users via storing

SEQUENCE FUNCTION

OUTPUT OFF TIMER FUNCTION

Before applying the sequence function, a series of different voltage,

current and duration steps must be edited by a PC to make a

sequence. CSV format, through RS-232C, LAN/USB (option) or

GPIB/USB (option) interface, is transmitted to the memory of the

PLR-series to sequentially execute steps consisting of voltage,

The output off timer function is to set the PLR-series to

automatically turn off its output after a certain period of time.

The shortest time setting is 1 minute. The setting range is from

1 minute to the maximum 1000 hours and 59 minutes. This

function can only be activated when power supply output is

being turned on.

When the voltage and current outputs exceed the preset conditions

of OVP and OCP, the PLR-series will be shut down so as to prevent

DUT from any damages.

OCP : the setting range is 5%~110% of the rated output

OVP : the setting range is 10%~110% of the rated output

UVP : the setting range is 1V ~ 110% of the rated output
