DC Power Supplies

DC power supplies

DC power supplies produce a DC voltage output and generate the output power by converting an input signal into a DC output signal.

For decades, DC power supplies have been changing the way engineers prove their design, understand the issues and ensure product quality. Available as a benchtop model or integrated into a system, single or multiple channel, programmable or non-programmable, constant or variable output, the DC power supplies we offer are suitable for a wide range of requirements, ensuring that we have a solution to meet your exact application needs.

AC Power sources and analysers

AC power sources and analysers

An AC power source is a device that is capable of supplying stable and reliable power to a load. Since your product will have to operate in the real world of unpredictable AC power, you need to design and verify its correct operation under a wide range of AC power inputs. Brownouts, dropouts, sags, and other irregularities are not unusual in many communities today. AC power sources and analysers have the features needed to easily accomplish this test goal either in an R&D environment or on the manufacturing test floor.

We provide a full range of basic and high-performance AC sources to help you test a variety of AC-powered devices. Basic sources provide reliable power while high-performance sources provide advanced measurements and waveform generation. On a bench or in a system, they offer optimal choices in voltage, current, capability, and performance. With an intuitive user interface, a flexible I/O (LAN/LXI core, USB, or GPIB), and low cost of ownership, the AC power sources and analysers we provide the quality and capabilities required for almost any application.

DC electronic loads for industrial applications

DC electronic loads

Electronic loads sink current and dissipate power in an accurate and controlled way out of a power source. They test power sources by emulating a device under test (DUT). Device manufacturers and design engineers use electronic loads to test power devices such as power supplies, DC-DC converters, chargers, adapters, batteries, solar panels, fuel cells, and more. By using the right software, you are able to simplify the creation of load profiles and data logging and characterise devices with visual measurements over time.

From benchtop models to modular solutions (combination of a mainframe with modules), we ensure that our solutions meet your expectations by offering the right instrument and support to enable you to succeed on your project.

Source Measure units for industrial applications

Source measure units

A source measure unit or SMU is a source and measurement resource for test applications requiring high accuracy, high resolution, and measurement flexibility. SMUs are sometimes also referred to as source monitor units. An SMU can precisely force voltage or current and simultaneously measure voltage and/or current.

An SMU combines the features of a digital multimeter, true current source, electronic load, power supply, and pulse generator, all into a single, tightly synchronised instrument. Source measure units are considered more useful than a combination of any of the five mentioned instruments due to the instrument’s high accuracy, performance, and versatility. 

Our source measure units are extremely cost-effective source/measurement solutions with superior performance. They are categorised into four areas: precision, application-specific, general-purpose, and basic. Available as benchtop or USB models, these instruments have excellent voltage and current sourcing capabilities at the highest precision and multiple software control options allow you to choose the solution that best fits your particular SMU application.

These solutions will improve overall test productivity and lower your cost of ownership.

Noise Sources to reduce noises

Noise sources

Noise measurements are key to assuring that added noise of a network is minimal. The need for highly repeatable, accurate, and meaningful measurements of noise without the complexity of manual measurements and calculations has led to noise figure measurement instruments with simple user interfaces. The noise figure of a network is defined as the ratio of the signal-to-noise power ratio at the input to the signal-to-noise power ratio at the output. Therefore, the noise figure of a network is the decrease or degradation in the signal-to-noise ratio as the signal goes through the network.

Our portfolio of noise sources is designed to cover the majority of measurement applications with a range of frequencies, Excess Noise Ratio (ENR), and coaxial connector types.

Power quality solutions

Power quality solutions

We offer advanced power quality meters, power quality solutions, and power management software. This technology simplifies the understanding of the quality of power itself and helps our customers to enhance electrical network power quality.
