functions

SPD3000C

Main Features
3 independent controlled and isolated
output: 32V / 3.2A×2, 2.5V / 3.3V / 5V /3.2A×1, total power 220W.

Series and parallel functions allows twochannels to be easily combined into one
output with more power output ability, doubling
the supplied voltage or current.
Each of the 3 channel’s outputs can be turned
on/off independently or all 3 turned all-on/alloff simultaneously.

Resolution:10 mV/10 mA
Supports panel timing output functions.
LED display; 32 V full scale, 4 digits; 3.2
A full scale, 3 digits
100V / 120V / 220V / 230Vcompatible
design, to meet the needs of different
power grids.

Parallel connection

Intelligent fan for temperature control,
effectively reduces noise.
Five groups of internal systemparameter storage. Supports data
storage space expansion.

Series connection

Supports SCPI commands & USB
device interface. Includes PC software.

Application field
Debugging in R&D

Design Features
High-resolution and high-precision output
High precision adjustability of as low as
10 mV & 10 mA steps. User’s DUT can bemonitored and analyzed under smallchanges in voltage and current.

About SIGLENTSIGLENT is an international high-tech company, concentrating on R&D, sales,
production and services of electronic test & measurement instruments.

SIGLENT first began developing digital oscilloscopes independently in 2002.
After more than a decade of continuous development, SIGLENT has extended
its product line to include digital oscilloscopes, isolated handheld

oscilloscopes,

function/arbitrary

waveform

generators,

RF/MWsignalgenerators, spectrum analyzers, vector network analyzers, digital multimeters,
DC power supplies, electronic loads and other general purpose test
instrumentation. Since its first oscilloscope was launched in 2005, SIGLENT
has become the fastest growing manufacturer of digital oscilloscopes. We
firmly believe that today SIGLENT is the best value in electronic test &measurement.
