Siglent SDL1030X 150 V/30 A 300W DC Load 0.1 mV, 0.1 mA readback


Siglent SDL1030X Programmable DC Electronic Load has a 3.5 inch TFT-LCD display, a user-friendly interface and superb performance specifications. The SDL1020X-E model features an input range of 150 V/30 A 300W and 0.1 mV, 0.1 mA Min. readback resolution

The Siglent SDL1030X DC Load leads with measurement resolution of 0.1 mV/0.1 mA and the base SDL1000X-E series resolution is 1 mV/1 mA and adjustable current rise times from 0.001 A/μs~2.5 A/μs. For remote communication and control, the SDL series includes S232/USB/LAN interface types. The SDL1030X delivers stability over a wide range of applications and can meet all kinds of testing requirements. including: Power, battery/handheld device design, industry, LED lighting, automotive electronics, and aerospace.

Steady state operating mode

The SDL features four operating modes to provide flexible test capabilities. In CC mode, the electronic load will sink a constant current, regardless of the voltage at its terminals. In CV mode, the electronic load will cause a constant voltage to appear at its terminals. In CR mode, the electronic load will behave as a fxed resistance value. As shown in the fgure, the electronic load will linearly change the current according to the input voltage. In CP mode, the electronic.

Dynamic test mode up to 25 kHz (CC)

The transient test allows switching between two different load values. A common application is to test the dynamic characteristics of a DC source or DUT (Device-Under- Test). The transient test function enables the load to periodically switch between two set levels (Level A and Level B). The highest frequency can be set to 25 kHz in CC mode. The highest frequency can be set to 12.5 kHz in CP modes.
