System-Related Functions

• Re-Energy: indicates the regenerative power.

• AHour: indicates the capacity of charge and discharge, when the battery

simulator function or battery test function is enabled, the capacity data

will be cleared.

• WHour: indicates energy data, when the battery simulator function or

battery test function is enabled, the energy data will be cleared.

7.7 External analog function (optional)

When the interface card selected by the user is DB25 analog interface (IT-

E1208), the analog interface can realize the external analog function.

The rear panel of this series is optionally configured with a DB25 analog inter-

face, through which, the following functions can be realized:

• Remotely control voltage and current values

• Control On/Off state

• Remotely monitor CC and CV states as well as voltage and current values

• Clear instrument faults

• Monitor the instrument loading state, On/Off state and fault state

• RS-485 interface connection. For detailed introduction about interface, refer

to 2.6.5 RS-485 Interface

• Before connecting the hardware equipment that controls the analog in-

terface, ensure that the hardware equipment would not output voltage

that is 20% higher than specified value. Otherwise, it would damage the

instrument. For example, during setting of voltage or current, the input

voltage cannot exceed 12V. Otherwise, it would damage the instrument.

• Under the analog remote control mode, the analog signal input pin can-

not be suspended, before enabling the external analog function on the

front panel, it is necessary to correctly connect the 1 (Vol_Pro), 15 (Cur_

Pro) and 17 (Cur/Vol_Pro).

• There is safe electrical isolation between the analog interface and the

DC terminal. Do not connect any ground wire of the analog interface to

the DC+ or DC- terminal on the instrument’s rear panel.
