Product description
The UNI-T UTL1020S-E is a programmable electronic DC load developed for testing, verification, and load analysis of power supplies, batteries, chargers, LED drivers, and other DC sources. The instrument uses high sampling speed and DSP-based signal processing to enable fast and accurate analysis of voltage, current, and power in both static and dynamic tests. The UTL1020S-E is designed for laboratories, development work, production testing, and service applications where advanced load control and detailed measurement analysis are desired.
The UTL1020S-E is primarily used for load testing of laboratory power supplies, battery systems, and DC converters where fast transient response, programmable load control, and detailed analysis of voltage and current behavior are desired. The instrument can also simulate real load variations for verification of power supplies and batteries under dynamic conditions.
