Siglent Technologies Introduces Programmable DC Loads

The new SDL1000X/X-E series of programmable, electronic DC Loads features an input range up to 150V/30A in 200 and 300 watt versions, starting at $539. 

SIGLENT Technologies has introduced the SDL1000X and SDL1000X-E series of programmable electronic DC Loads, which are designed for battery, solar cell, and power supply testing. The SDL1020X/X-E models offer an input range of 150 V/30 A with 200 W total power dissipation, while the SDL1030X/X-E’s have an input range of 150 V/30 A up-to 300 W. The X type provide a measurement resolution of 0.1 mV/0.1 mA, whereas the economical X-E type offers 1 mV/1 mA.

A 4-wire sense compensation mode is also implemented to remove any potential error due to a voltage drop in the connection wires. These DC loads support all the common modes of operation: CC, CV, CR and CP.

One of the most important features of this new e-load series is its high-speed response performance. In dynamic test mode, the highest frequency of periodical switching between two user-defined levels (Level A and Level B) can achieve 25 kHz. The adjustable slew rate can be set by the user up to a value of 2.5 A/us.

All models come standard with a 3.5-inch TFT-LCD display and user-friendly interface. As part of this functionality, operators can use the Program function (maximum 50 groups) and List function (maximum 100 steps) to create complex discharge profiles, which can be useful in battery charging circuitry design. The SDL1000X/X-E series is equipped with additional features that include an LED-test mode (CR-LED) designed specifically for LED driver testing. This mode is able to emulate LED’s actual characteristics such as single continuity. Furthermore, the instruments have a voltage threshold function, trend chart function, and voltage Rise/Fall speed test.

For maintaining security and reliability, the SDL1000X/X-E series provide comprehensive protection features like over-current (OCP), over-voltage (OVP), over-power (OPP), over-temperature protection (OTP), as well as reverse voltage protection to prevent incorrect wiring connections to the Device-Under-Test.

The price for this series of electronic loads starts at $539.
