Cell Lab ET53 Programmable DC Electronic Load Battery Tester

High-precision programmable DC electronic load for battery discharge, power supply evaluation, LED testing and automated production line inspection.

General Description

The Cell Lab ET53 Series Programmable DC Electronic Load is a compact, high-accuracy electronic load designed for battery testing, power supply evaluation and electronic product validation. With 1 mV / 10 mV voltage resolution and 1 mA / 10 mA current resolution, the ET53 series delivers stable, repeatable performance for both R&D laboratories and production line testing.

Supporting 12 common operating modes including CC, CV, CR and CP, as well as advanced functions such as battery discharge testing, LED testing, transient analysis, scan testing and list mode, the ET53 series provides a comprehensive solution for testing chargers, switching power supplies, linear power supplies and battery systems. The 3.5-inch TFT LCD display, intuitive user interface and multiple communication options allow easy integration into automated test systems.

Key Features

• Multiple programmable load modes – CC, CV, CR, CP, CC+CV and CR+CV for versatile testing scenarios.
• Battery and LED test functions – Dedicated discharge and LED testing modes for production and R&D.
• Dynamic performance evaluation – Transient, scan and list test modes for analysing power supply response.
• High-resolution measurement – Up to 1 mV / 1 mA resolution with stable read-back accuracy.
• Comprehensive protection mechanisms – Over-voltage, over-current, over-power and over-temperature protection with intelligent fan control.
