Chapter2 Quick Start; Brief Introduction - ITech IT8300 Series User Manual

This Chapter will introduce power-on check steps of IT8300 Series to ensure
normal start-up and usage under initialization status of the load. Besides, to
facilitate usage, this part also displays the functions of front board, rear board
and keyboard keys as well as display functions of VFD (Vacuum Fluorescent
Display) to a quick view of load appearance, structure and key usage functions
before operation.

2.1 Brief Introduction

IT8300 series provides unique regenerative function. It can convert the
absorbed DC power into AC power and feed it back to grid. That greatly saves
energy and reduces heat dissipation cost for users. IT8300 adopts high power
density design, e.g. for 3 U size, it can absorb power up to 10.5 kW. For high
power test requirements, IT8300 supports master-slave paralleling and current
equalized distribution, the functions expand the power without degrading the
performance specifications. Moreover IT8300 has multiple functions such as
the automatic grid-state detection, on-grid electricity accumulation, islanding
protection, battery-test function, dynamic mode, LIST function, etc. The built-in
interfaces include LAN, USB, RS232, RS485, CAN and analog interface, which
are very convenient for PC and PLC remote control and user calibration. The
various functions make IT8300 series suitable for high-capacity battery test,
high-power power supply life-circle test etc.
