Chapter 1 General Information
1.1 Introduction
SM6027A DC Bias Current Source adopts high-performance MPU and can provide a
constant current range from 0A to 20A. The maximum current output can reach 0-120A
by connecting the slave. SM6027A can be used with Scientific LCR meters. It is
suitable for the AC/DC superposition test of magnetic inductors and provides the
convenient and practical magnetization current source for the characteristic analysis
of magnetic materials.
The instrument can accept real-time modified current at work and respond
immediately.
It adopts a new generation of AC-DC superimposed test principle to adapt to high-
precision and high-frequency test needs.
The instrument has a new design-friendly graphical operation interface and offers a
variety of control modes: manual key control, foot switch control and remote command
control.
1.2 Specification
1.2.1 Current Accuracy
The main machine: 0.000mA~20.0A 1A/5A/20A three current gears;
Up to 5 slaves can be connected, the output current range is 0.000mA ~ 120.0A.
1.2.2 Display
480 × 800 16: 9 24bit true color TFT LCD
1.2.3 Control
Physical keys: START / STOP button to control the start or close of the current output;
Foot switch: two kinds of foot mode to control the start or close of the current output;
RS232: remote control can be performed by commands.
1.2.4 Frequency response
0Hz ~ 2MHz
1.2.5 Driver
Output voltage: 7.5Vmax
The maximum allowable DC resistance of the DUT: Rmax= (Ω);
Scientific
User Manual SM6027A 6/31
The maximum allowable inductance of DUT: Lmax= (mH)
The maximum allowable time of open circuit, overload, overheating or unbalance:
automatic protection <1ms;
The smallest step of sweep:
I ≦1A: 5mA
I ≦5A: 25mA
I ≦120A: 100mA
1.2.6 Interface
SM6027A is equipped with SlaverLink interface, RS232C interface and USB Device
interface.
SM6027A can be connected directly with the Company's L-Meter or LCR Bridge and
can be controlled by some L-Meter or LCR Bridge. It can be controlled by all upper
computers with serial port (the control instruction set must follow the SCPI instruction
set provided by this manual).
1.3 Main Functions
•
Only capable of forward current output. If directional current is needed, please
change the connection direction between DUT and the output end.
•
Display the real-time working state of the main machine and the slaver.
•
With two foot-control mode, strong adaptability.
•
Provide SCPI command
•
With user-friendly graphical interface, can quickly indicate the working status of
the instrument, convenient and efficient control.
•
Provide English and Chinese operation interface.

1.4.5 Precautions for Usage
•
Please do not use the tester in dusty, vibrating, direct sunlight and corrosive gases
and other adverse environments.
•
When the instrument is not used for a long time, please put it in the original box or
similar box and stored in a ventilated room with temperature of 5℃~40℃and
relative humidity less than 85% RH. Do not store the tester in a corrosive
atmosphere containing harmful impurities and should avoid direct sunlight.
•
The instrument has been carefully designed to reduce clutter due to AC power
input. However, it should still be used under low noise conditions. If that is
inevitable, please install the power filter.
