Vitrek Launches Best-In-Class Programmable DC Load Product
The Vitrek DL Series offers industry-leading performance in 125W-500W applications; supports best-in-class transient loading capability (from 0.1µW resolution to 14.5kW pulses); features high-speed pulse loading up to 100 kHz; boasts up to ten times better measurement accuracy.
Poway, CA—December 12, 2019—Vitrek, the leader in high-voltage test and measurement equipment, introduces the DL Series of digital, programmable DC loads, designed to support the testing requirements for the latest generation of off-line power supplies, dc-dc converters and LED drivers. The DL Series is also equipped to handle a wide range of battery testing requirements. The devices are offered in three power ratings (125W, 250W and 500W), each with input voltages of 0-150V or 0-500VDC. Unlike comparable programmable DC loads, the DL Series is capable of supporting loading sequences utilizing constant voltage (CV), constant resistance (CR), constant current (CC) and constant power (CW) in any combination in single or arbitrary sequences of up to 100 steps.
The DL Series provides high-current transient loading capability twenty times higher than other units in this class while also being capable of generating µA loads. Measurement accuracy is typically in order of magnitude better at lower loading levels and double that of competing devices at higher loads. The istruments allow for a current or power sweep of up to 500 steps in each direction to and from set values and a voltage dependent current loading mode for complex variable output supplies. Standard OCP/OPP/OTP/OVP features and battery test modes are among other loading modes also included.
The instruments feature a comprehensive self-test function, providing assurance that all loading and measurement circuitry is properly functioning. Multiple interfaces are included as standard to allow for fully automated use. Additional unique features of the DL Series include historical data logging capability, both graphical and numerical, and graphical X/Y plotting of V vs A or W using swept loading. The DL Series offers leading transient performance in timing – with pulsed loading up to 100kHz – and wave shape, with the unique ability to view the current and voltage waveforms directly on-screen using the built-in internal scope.
“The DL Series of programmable DC loads was designed to enable users to conduct real-world testing,” said Chad Clark, Vitrek’s VP Sales & Marketing. “These instruments feature a high-resolution, touchscreen display. The intuitive touchscreen operation – with built-in data history and scope mode – are popular features of the entire family of Vitrek instruments.
