2.2 Introduction
This user’s manual introduces the specifications, installation, operation and
programming of IT8700 series DC electronic loads. There’re two parts in
IT8700 DC electronic loads, mainframe/ extended frame and modules. The
frames mentioned are IT8702/IT8701P/IT8702P mainframe and
IT8703/IT8703P extended frame. The modules mentioned are divided into two
kinds: single channel module (IT8731/IT8732/IT8732B/IT8733/IT8733B/
IT8731P/IT8732P/IT8732BP/IT8733P/IT8733BP) and double channels module
(IT8722/IT8723/IT8722B/IT8722P/IT8723P /IT8722BP). Each module should
be installed into frame to work. The range of every module’s specific voltage,
current and power will be introduced in the Chapter 5: specifications in detail.
There are up to 4 channels in IT8701P mainframe. After extended with IT8703
or IT8703P mainframe, it can be up to 12 channels. The dimension of IT8702 is
the same with IT8703. The difference is that IT8702/IT8701P/IT8702P are main
control frame while IT8703/IT8703P is an extended unit. There are up to 8
channels in IT8702/IT8702P mainframe. After extended with IT8703 or IT8703P
mainframe, it can be up to 16 channels. All panel operation and programming
are also carried on the IT8702/IT8701P /IT8702P main panel.
