Chapter 1 Introduction
M88XX Series power suppliers are high performance single-output programmable DC power
suppliers with communication interface, possessing the character of fast rise time speed (The rise speed
of M8811 power supplier can be less than 10mS and that of M8851 can be less than 20mS) The
combination of bench-top and system features in these power suppliers provides versatile solutions for
your design and test requirements. The M88XX Series can not only be programmed through the
keyboard on the panel, but also be functioned as voltmeter and milliohmmeter, which will bring great
convenience to the users. As a regeneration product of ordinary programmable power suppliers, M88XX
Series power suppliers are more cost-effective.
M88XX Series power suppliers’features
• Low Periodic And Random Deviation (PARD) and noise
• High resolution and accuracy (0.1mV/0.01mA)
•Installing a high-accuracy 5 1/2 voltmeter and milliohmmeter
•Supporting high-accuracy and dynamic programming output
• High –luminance VFD screen and two lines& four ways display
• Smart fan will be automatically initiated according to the temperature.
• Supporting remote voltage compensation and multidata storage
• Supporting external trigger input and output.
• Power-on-self-test，software calibration and standard designed instrument stand
•Supporting TTL level Serial communication interface
