The PDL series DC loadbank is an advanced tool for testing, discharging, and evaluating the performance of various industrial batteries. This device, capable of operating in three operating modes CC (constant current), CP (constant power) and CR (constant resistance) and with a wide voltage range from 10 to 500 volts, is ideal for testing nickel-cadmium (Ni-Cd), lead-acid and lithium batteries. The compact design and high power density make it easy to use in space-constrained environments. Precise current control with accuracy of less than 0.5 A ensures a stable and reliable discharge. The Central Supervision Unit (CSU) monitoring and control module enables remote monitoring and system management. Test results can be viewed, saved and edited on a personal computer via the Niawell CSU Logger software provided with the device. In addition, comprehensive data logging, real-time charts and generation of PDF reports enable precise and professional analysis of battery performance. The simple user interface, quick setup and stable operation make the PDL a smart choice for industrial testing centers.</br></br>

Practical Example
In a test scenario, the PDL device is connected to the battery and the warning thresholds for current and voltage are preset. After the discharge process begins, the device maintains the current at the set value in constant-current mode (CC). As the voltage gradually decreases and reaches the warning level (a value slightly above the cut-off voltage), the device triggers an alarm. If the voltage continues to drop and reaches a critical level that risks deep discharge of the battery, the PDL automatically stops the discharge process to prevent damage to the battery.</br>In case of a temporary power interruption, the device resumes the test process from the same point after power is restored. All recorded data are stored in the device memory and can be easily transferred to a computer via the Niawell CSU Logger software and viewed and managed as PDF.
For accurate measurement of battery voltage, especially in applications with long cables or high currents, it is recommended to use separate sense lines (sense lines) to compensate for voltage drop.
