MULTI-RANGE OUTPUT OPERATION
PRODUCTS IN THE SERIES
Compared with the maximum power output of the conventional
power supply that is calculated by the maximum output voltage
multiplies by the maximum output current, the PSB-2000 series,
defying the formula, has a unique characteristic of multi-range
output (voltage and current). This distinguishing feature, under
the same maximum power output range, can output a higher
voltage with a smaller current and vice versa. For instance, for a
conventional power supply with a maximum power output of
360W, the maximum voltage and current outputs are likely to be
10V and 36A respectively. Comparatively, PSB-2400L, with the
maximum power output of 400W, provides voltage and current
output ranges of 0~80V and 0~40A. The maximum current of 5A
will be provided when the voltage reaches 80V and the maximum
voltage of 10V for the maximum current of 40A. PSB-2400L,
breaking the limitation of Pmax=Vmax x Imax,, broadens voltage
and current application ranges. The following diagrams illustrate
the voltage and current comparison between the multi-range
output power supply and the conventional power supply.
The operation area of a Conventional Power Supply
The operation area of a Multi-Range Power Supply for PSB-2000 Series
There are six models in the PSB-2000 Series. Model type, output voltage, output current and output power are as follows :
* PSB-2800LS, a booster unit acting as slave to extend current, can not operate alone. It must operate with PSB-2800L master.
** The maximum current under the highest output voltage is power/voltage. For instance, when PSB-2400L outputs 80V the
maximum current is 400W/80V = 5A .
*** Same as above. When PSB2400L outputs 40A the highest voltage is 400W/40A = 10V .

Output Voltage (V)
The PSB-2000 Series is a high power density, programmable and multi-range output DC power supply. There are six models in the series
including one power booster unit. The PSB-2000 Series has the output voltage of 0~80V and 0~800V, and the output power ranges of 0~
400W and 0~800W. The multi-range output functionality facilitates flexible collocations of higher voltage and larger current under the rated
power range. Both series and parallel connections can be applied to the PSB-2000 Series to fulfill the requirements of higher.
The PSB-2000 Series provides analog control interfaces on the rear panel to control PSB-2000 Series output via the external voltage or to
externally monitor voltage and current output status of power supply. The PSB-2000 Series panel can be rotated 90 degree angle suitable
for vertical or horizontal position to accommodate the ideal space utilization.
The PSB-2000 Series protects over voltage and over current. The power supply output function will be shut down to protect DUTs while
the protection mechanism is triggered to function. When conducting battery charging operation, the Hi- mode of the PSB-2000 SeriesW
will prevent reverse current from damaging power supply.
The PSB-2000 Series provides three sets of preset function keys to memorize regularly used settings of voltage, current and power that
users can recall rapidly. The sequence function, via RS232C, USB interface or optional GPIB interface, can connect with the computer to
produce output power defined by sequence of a series of set voltage and current steps that are defined by the computer. This function is
often used to establish a standard test procedure for the verification of the influence on DUTs done by the swiftly changing operating.
