PPH-1503D & PPH-1506D & PPH-1510D
Programmable High Precision D.C. Power Supply
Description
PPH-15xxD high
precision measurement capability achieves the maximum resolution of
1mV/0.1uA and the smallest pulse current width of 33us that satisfy
customers’ measurement application requirements of high resolution
and pulse current. Fast load current variation will result in
voltage sag for general power supplies that will have an impact on
DUT’s internal circuit operation.
PPH-15xxD is equipped with the excellent transient recovery time,
which can, in less than 40us, recover the output voltage to within
100mV of the previous voltage output when the current level changes
from 10% to 100% of the full scale. Furthermore, conventional power
supplies do not have sufficient response speed to promptly respond
to set voltage value once the set voltage is changed. PPH-15xxD has
a rise time of 0.2ms and a fall time of 0.3ms, which are 100 times
faster than that of conventional power supplies.
Therefore, PPH-15xxD can provide DUT with a stable output voltage
even when DUT is operating under large transient current output. The
internal high-speed sampling circuit design of PPH-15xxD, with the
sample rate of 64K, can conduct pulse current measurement without
using a current probe and oscilloscope. The current read back
accuracy is 0.2%+1uA (equals to 11uA) at 5mA range, and the read
back resolution is 0.1uA that allow DUT to be measured with a high
accuracy level.
Unlike battery, general power supplies, which do not have the
characteristics of fast transient recovery time, can not maintain a
stable power supply for cellular phone, wireless device, and
wearable device which produce large
transient pulse current load for
hundreds of μs to dozens of ms when in use. PPH-15xxD, different
from general power supplies, has the characteristics of fast
transient recovery time. While simulating battery to output pulse
current, PPH-15xxD can quickly compensate the voltage drop caused by
pulse current.
PPH-15xxD’s CH1 has the built-in battery simulation function, which
can define output impedance settings so as to accurately simulate
battery’s impedance characteristics during battery discharge. Fast
transient recovery time and built-in battery simulation function
together facilitate PPH-15xxD to accurately simulate battery’s real
behavior pattern so as to conduct product tests.
