Manson Engineering Industrial HCS-3400 USB User Manual

Remote Programmable Laboratory Grade Switching Mode Power Supply
1. INTRODUCTION
This family of efficient, upgraded SMPS with small form factor, auto cross over CV CC, 3 VI presets, remote control
offers unique solution for various loading conditions and applications.
The dual action (coarse/fine tune) rotary encoder tuning with MCU makes setting the voltage and current levels ever so
smooth, precise and fast. Setting, changing, and checking the current limit level can be done easily without sparking the
output poles.
The remote control functionality allows the output power on/off, voltage &current be adjusted without touching the
front panel of the power supply.
The USB port is added for access to computer to run cyclical operation with Max. 20 programmable sets of preset of
voltage and current with different time duration and up to 999 cycles.
It is suitable for a wide range of applications such as laboratory, telecommunication, production testing, field test of
voltage critical distant load, powering of dc network and etc...
The 3 user defined presets facilitate quick access to frequently used VI settings.
