Brief description of the principle: TEC-12H battery discharge meter is also a battery capacity tester, which is designed for low-voltage single batteries, and the maximum discharge current is 40A. The instrument adopts the principle of closed-loop control, so that the discharge current reaches the set value and does not change with the voltage. The detector uses manganese copper resistors with low temperature drift for current sampling, and MOS tubes as current control devices, so that the controlled current can be within the error range of 0.5%. The MPU is used to control the entire circuit, including the display interface, adjustment buttons and timing. The timing of this tester is based on the product of current and time, which is used as the calculation of battery capacity.
UI:
? Intuitive display: The tester uses two 4-digit digital tube displays, and the upper screen displays the measured voltage during operation. The lower screen can be switched to display capacity (AH), cut-off voltage (V), current (A), temperature (℃), and there are corresponding LED lights to indicate.
? Measured voltage: Displays the actual voltage of the battery under test or other power sources under test. Displayed units are volts.
? AH: Displays the capacity value. As the discharge process progresses, this value has been accumulated and stopped after the discharge is completed. The units shown are AH.
? Cut-off voltage: It is a parameter set by the user. When this voltage is reached, the detector will automatically stop discharging.
? Current: It is the discharge current of the detector.
? Temperature: It is the temperature of the heat sink of the detector, and the starting of the fan and the automatic control of the power are all based on this measurement temperature.
Technical Features:
? It can be controlled by the control board, and it can be controlled by the RS485 bus without the control board.
? There are two options for the display screen: integrated in-line screen and external led screen. The external screen is more suitable for users to DIY.
? The maximum withstand voltage is 5V, and the maximum power is 175W.
? Maximum current: a single battery with a voltage above 2V can discharge up to 40A.
? It can work independently without the computer, and can also be controlled by the computer as the upper computer.
? There are 2 data interfaces: USB, RS485 (Modbus).
? Modbus (RTU) industrial bus, using RS485 interface, can realize the networking of up to 90 devices.
? Intelligent power limit, with over-temperature protection, anti-reverse protection function.
? With multiple protection functions, including: anti-reverse protection, over-temperature protection, maximum power limit, under-voltage protection.
? Power-off data storage function: If the power is off during the measurement process, the accumulated capacity can be automatically retained.
? Music alarm after the measurement, three music options: Beethoven Symphony No.9Are you sleepingKamata March, can also be set to mute.
technical parameter:
? Power supply: 12Vdc (the actual required current is about 1.0A), and the power supply interface is 5.5/2.1mm.
? Current range: 1~40A.
? Current adjustment solution step size: the adjustment step size below 10A is 0.1A; the adjustment step size above 10A is 0.5A.
