## Description

Adjustable electronic load for testing the capacity of batteries and DC sources, operates between 1.5 and 25V and allows setting the current up to 5A, dissipates up to 35W with integrated radiator and fan. The display shows voltage, current, power, Ah and discharge time, and the separate 5V power supply via USB reduces measurement errors.
Capacity tester module for accumulators, which can be used as an adjustable load, which supports voltages between 1.5V and 25VDC, a load current set by potentiometer between 0.00 and 5.00A. This module can dissipate a total power of up to 35W, using the integrated radiator and fan.
The supply circuit and the load circuit are separated in this way, eliminating measurement errors, given the fact that the module, with the fan on, consumes somewhere around 200mA.
The working voltage of the module is 5VDC, the power is supplied through the male USB or MicroUSB plug. Alternatively, a 5V supply can be attached directly by tinning the +5V and -5V pads (GND).
The display allows the following information to be displayed:
- Input voltage
- Current consumed in real time (X.XXA)
- Power in real time in W (XX.XXW)
- Cumulative discharged current in Ah (XX.XXAh)
- Cumulative operating time in hours (XX:XXh)
- Temperature of the module in degrees C (hold down the SELECT button to switch between displaying Voltage or Degrees C)
