Touch screen display enables easier use for power supply family

The SGX Series is the next generation of the successful SG line of programmable DC power supplies. The line is designed for load transient response, very low noise, and high power density. The SGX Series combines onboard intelligent controls with the power electronics common to all SG family supplies.

These controls enable sequencing, constant power mode and save/recall of instrument settings. Additionally, looping of sequences makes the SGX suitable for repetitive testing.

Users can quickly and expertly control the DC supply with the intuitive touch screen display. The touch screen function group icons include a dashboard, output programming parameters, measurements, sequencing, configuration, control interfaces, applications, and system settings.

Function selection and parameter entry can be achieved either by direct selection from the touch screen or by using the encoder selector button. The control resolution is adjusted by a rate change algorithm that combines the benefits of precise control over small parameter changes with quick sweeps through the entire range.

The popular Sorensen SG product family; now at 96 models, is one of the industry’s largest DC power supply families. The SGX product line complies with all EMI and EMC Safety requirements as well as EU RoHS directives.

The SGX Series offers test system builders a variety of features and options designed to simplify system configuration and testing processes:

• Up to 15kW in 3U and 30kW in 6U: 3U SGX supplies are available with maximum power output levels of 4-15kW; 6U SGX supplies are available with maximum power output levels of 20-30kW.
• Easily parallel chassis for up to 150kW: Up to five units can be operated in parallel to provide additional current output.
• Intuitive touch screen display: Complete control of the power supply at your fingertips lets you be an expert from the first use.
• Automatic crossover from constant voltage to constant current operation.
• Fast load transient response: The supply recovers within 1ms to ±0.75% of full scale of steady state output for a 50% to 100% or 100% to 50% load.
• Power factor more than 0.9 typical: Power factor correction (PFC) comes standard in 10, 15, 20, 30, 50, and 1,000V models. PFC is available as an option in all other models.
• Standard RS232 and LXI Ethernet: Optional IEEE-488.2 GPIB and isolated analogue I/O interfaces available.
• Blank panel (no display) versions available for slave units: The blank panel version protects ATE from manual or accidental parameter changes.

Applications for the SGX Series are wide ranging, including rack-mount ATE, product validation, process control, burn-in, materials research, battery charging, water treatment, electrolysis, accelerator magnet drive, and power electronics testing among others.
