Vitrek DL550 DC Electronic Load

Overview

The Vitrek DL550 is a versatile DC electronic load with integrated color touchscreen display for configuration and measurement. It provides high-accuracy voltage and current measurements (0.05%) with the ability to resolve pulse and sweep steps as short as 20μs and pulse frequencies up to 100kHz. The DL550 can generate loading from kilowatts down to microwatts at voltages up to 500V, making it adaptable to higher-voltage applications including power supplies, industrial electronics, and general laboratory testing.
