Function and Features
3.14 Charge Protection
This power supply is applicable to battery charge test and provides charge
protection during battery charge test. Even when the internal load is activated,
the UUT will not be discharged. During charge protection, the power supply
switches off output as follows.
1. Power output is switched off (On/Off key is lighted off) and power supply will
stop output.
2. The internal load discharges the capacity energy at power output through a
small current.
• When capacity energy discharge of the power supply is normal, it means
that no energy storage device is found. Continue to discharge the current
to 0V. To end.
• When abnormal capacity energy discharge is detected, the UUT
connected at the output terminal is a battery or other energy storage
devices. To step3.
3. The power supply will automatically adjust the internal load discharge
current to 0 and stop discharge.
This protection function forbids UUT discharge to guarantee device safety. It
also avoids insufficient charge during battery charge test.
3.15 Static Protection Function of Battery
The power supply is designed with the battery protection function in static state
(when the output is off). If the DUT is the energy storage device like battery, the
power supply will prevent battery from consumption.
1. Press [Shift]+[P-set]( Menu ) to enter the system menu.(Menu).
2. Select CONFIG→Load-Status→Load, enable the internal load. (Default
setting is Off status)
3. Press [Esc] to exit menu setting.
4. Select Static-Curr and turn off static current function when output is Off.
If the DUT is the energy storage device like battery, you need to turn off the
static current function. Otherwise, the current of the battery will be
consumed and flow backwards to the power supply. The value of the current
flowing backwards of different models is not the same. It ranges from 0.1A to
0.5A approximately.
