The FZ35 5A 35W Electronic Load Tester is an industrial-grade, long-life device that is equipped with a fast-rotating long-life ball fan, making it ideal for continuous discharging and long-period discharge or aging tests for factory products. It can be used to test the output current capability of chargers, batch aging tests for chargers, and battery load capacity.

15>.Work Temperature: -40℃~85℃
16>.Work Humidity: 0%~95%RH
1>.Display current A, voltage V, power W, capacity Ah and Discharge time
2>.Automatically count discharge capacity and discharge time
3>.Supports setting maximum discharge capacity (OAH) and maximum discharge time (OHP). (Achieve unattended for power aging test)
4>.Intelligent temperature control fan.The fan automatically starts when the power is greater than 10W or the temperature is greater than 40℃
5>.Rotary coded potentiometer for precise current adjustment to 0.01A
6>.The current can be locked to prevent misoperation
7>.Data group function:user can choose whether to accumulate the capacity value and running time of the previous phase
8>.Support UART data communication
1>.FZ35 supports reverse protection for input terminal and output terminal.
2>.OVP over voltage protection.
The default protection value is 25.2V. But user can modify the values as required.Screen will display OVP and flashing after start over voltage protection.
3>.OCP over current protection.
The default protection value is 5.10A.But user can modify the values as required.Screen will display OCP and flashing after start over current protection.
4>.OPP over power protection.
The default protection value is 35.5W.But user can modify the values as required.Screen will display OPP and flashing after start over power protection.
5>.OTP over temperature protection.T
he default protection value is 80℃. It can not be modified! Screen will display OTP and flashing after start over temperature protection.
6>.LVP under voltage protection.
The default protection value is 1.5V. But user can modify the values as required.Screen will display LVP and flashing after start under voltage protection.In the battery discharge test, setting the appropriate LVP can effectively prevent the battery from being over-discharged, so as not to damage the battery.
Automatically display the last parameter value.
7.Discharge capacity and discharge time statistics:
1>.Discharge capacity statistics:FZ35 start to statistics when load current is not zero. After the next load current is zero, it is considered that a discharge process is completed and the statistics are over.
2>.Discharge time statistics: FZ35 start to statistics when load current is not zero. After the next load current is zero, it is considered that a discharge process is completed and the statistics are over.
8.Set OAH and OHP:
1>.Set maximum capacity OAH:FZ35 automatically stops working and flashes "OAH" on screen when the load discharge capacity is higher than the set maximum capacity after enable OAH function.The capacity statistics are automatically cleared after the OAH alarm is released.
2>.Set maximum discharge time OHP:FZ35 automatically stops working and flashes "OHP" on screen when the load discharge time is more than the set maximum discharge time after enable OHP function.The discharge time statistics are cleared automatically after the OHP alarm is released.
3>.The OAH and OHP can be perfectly implemented unattended for power aging test.
4>.FZ35 will record discharge capacity and discharge time even if OAH and OHP are not enable.But FZ35 stops working after reaching the set value if OAH and OHP are enable.The running time of the FZ35 is the countdown mode when enable OHP.
9.Data group function DAT:
1>.DAT0:Only flashing and display the capacity value and running time of the previous stage, and not adding to the next stage.
2>.DAT1:Flashing and display the capacity value and running time of the previous stage, and automatically added to the next stage.
10.Run interface description:
1>.Press ‘ON/OFF’ button to turn ON FZ35 after power on.
2>.Set current value by rotary potentiometer.
3>.Press potentiometer to switch display parameter on the second line.The first line display voltage and the second line display current/power/capacity/time.
4>.Screen will display current when rotary potentiometer at any display interface.
5>.Keep press ‘ON/OFF’ for more than 3 seconds to lock parameter at current display interface.Screen will display lock symbol if enable data lock function.At this time, the load current cannot be adjusted in real time by the rotary potentiometer to prevent misoperation.
6>.Keep press ‘ON/OFF’ for more than 3 seconds to clear the corresponding capacity/time data at capacity/time display interface.
11.Setting interface description:
1>.Keep press potentiometer for more than 3 seconds to enter set parameter interface.
2>.Set load current by rotary potentiometer.Increase the current value clockwise.
3>.Switch set parameter by press potentiometer.
4>.Press ‘ON/OFF’ button to enabled or disabled OAH(OHP) function at OAH(OHP) display interface.Screen will display ‘----’ if disabled OAH(OHP) function.
5>.Rotary potentiometer to set value at OUP/OCP/OPP/LUP/OAH/DAT parameter.
6>.Keep ‘ON/OFF’ button to set capacity range at OAH interface.Each time press button, the decimal point moves by one, and then rotates the potentiometer to modify the value.The capacity range is 9.999Ah/99.99Ah /999.9Ah/9999Ah.
7>.At OHP set interface,the second line will display ‘--:--’.User need press ‘ON/OFF’ button to set hours and minutes parameters and then rotary potentiometer to set value.
8>.Keep press potentiometer for more than 3 seconds to save parameters after setting is complete.Then exit the settings interface.
1>.Connect to work voltage at ‘V+’ and ‘V-’.
2>.Set right parameters as set manual.
3>.Remove work voltage and connect load.
4>.Re-power.Test and use.
1>.It can not output voltage. User need connect load power supply for load.
2>.Please read use manual and description before use.
