Description:

• This module is a constant current electronic load. It uses high-precision DAC loop control technology to control output currents for power supplies or batteries, so that the current does not change when the voltage changes. It is a load itself, so you no longer need another external load discharger.

• This is a linear electronic load, not a PWM mode.

• This module will automatically calculate the product of discharge current and time to detect the battery capacity.

• This module can be used as an electronic load to verify the battery or power output capacity.

Parameters:

• Max Current: 3.5A; error: <=0.5%
• Max Power: 16W
• Operating Temperature: -20~70 Celsius

Features:

• Encoder switch (shuttle) operation, easy and convenient
• Precise current, the full range error is within 0.5%
• Integrated fan discharge power can be up to 16W, and the fan will be auto on/off according to the power
• Supports 4-wire measurement and can measure the internal battery
• Max connection voltage 15V, and power-off voltage can be adjusted randomly in the range of 1.0-12V; step length: 0.05V
• When the battery current is not enough, the detector will automatically adjust the set current until the actual current meets the set value; when the actual current is lower than 40% of the set value, the detector will end up discharging
• MINI USB interface (5V voltage) power supply; the actual current consumption is within 240mA
• Max detection capacity is 500000mAH (500AH)
• Adopts 4-wire battery clip, and measures internal resistance

Usage:

• Turn on the power, check the battery type, and set the turn-off voltage.
• Connect battery to I+ and if you need to measure the internal resistance of the battery, use a four-wire and make sure the voltage measuring terminal is connected to the detector.
• Setting the turn-off voltage: Turn the knob to "off voltage", press the switch, then the LED will light up. "Turn off voltage" lights flashing, means that the turn-off voltage is in set state, turn the knob and you can change the size of the shutdown voltage. The minimum adjustment step is 0.05V, to the required set value, then press the switch. The parameter is stored in the detector to complete the turn off voltage parameter settings.
• Setting the current: Turn the rotary switch to the "current" display mode. The setting method is the same as above. The adjustment step is 50mA within 500mA. The adjustment step is 100mA above 500mA, and the maximum current is 3.5A.
• Start/Stop: For starting there are two modes: "mode 1" is in the "capacity" display state - press the switch to start (start and then press the switch is paused), this start method measures battery voltage in the battery open circuit voltage. When measuring the battery you should use this start method. Use this mode if using a 4-wire battery clip input, and you will be able to measure the battery resistance. "Mode 2" is in the "measured voltage" display mode, press the switch, then the starting method of the measured voltage is the line voltage, and the power supply or mobile power should be activated in this mode. After the start of the discharge LED lights begin to flash, digital display discharge capacity. After the discharge starts, the detector will heat; when the discharge power is greater than 2.2W fan starts and if it is less than 2W, the fan will close.
• End: When the battery voltage is lower than the shutdown voltage, the detector stops discharging the battery, the measurement is completed, then the digital tube flashes and shows the final discharge capacity.
• Measuring again: After completion of the measurement, the detector flashes and shows the capacity that has been completed. You must clear the capacity data to make the next measurement. Hold the switch for 3 seconds or re-start to do this.

Special Functions:

• Maximum power limit function: TEC-06 can limit the maximum power of the discharge. When the user sets the discharge power to greater than 16W, the detector can automatically adjust the discharge current so that the power is within 16W.
• Battery discharge & capacity detection function: When the maximum discharge current of the battery can not reach the set value, the detector will automatically reduce the discharge current.
• Cycle display function: In the "internal resistance" display mode, click the switch, then the detector will automatically cycle to display five digits.
