Excellent industrial design
A perfect combination of art and technology. Not only beautiful and fashionable, but also durable, accurate and stable.
4.3-inch color display
The set values and actual output values of the four channels are displayed on the same screen which makes users clear at a glance. Built-in V\A\W value and waveform display make the change trend all in control.
List and data recording functions
The list and data recording functions generate a variety of complex sequences by editing the single-step voltage, current and time to meet the complex test requirements, and record the actual voltage, current and power data of each step through the data recording function, and also generate waveform diagrams.
Low ripple noise, low load regulation rate, fast transient response
Low ripple noise: < 350 μVrms / 2 mVpp, meets the demand of high purity power supply. Low load regulation rate: Voltage: ≤0.01% + 2mV, current: ≤0.01% + 250μA, calmly copes with the change of load. Fast transient response time: ≤50μs, meets the needs of rapid voltage change.
Over voltage, over current, over temperature protection functions
Provides the overvoltage and overcurrent protection functions. You can flexibly set the overvoltage and overcurrent parameters to effectively protect loads.
Four modes: independent, series, parallel, tracking
The series and parallel functions can combine two power supplies into one power supply to obtain double voltage or current, expanding the applicable range and flexibility of the power supply.
Rich interface configurations
USB HOST, USB DEVICE, LAN, 4-line digital I/O interface; RS232/RS485 (HDP4324B/HDP4424B); GPIB (HDP4324H/HDP4424H); Support U disk (FAT32 format, Flash) storage; Support SCPI remote command control; Supports post output function, 2-wire/4-wire mode display.
Convenient computer connection
Plug and play, safe and stable, provide free secondary development instructions, making it easy to form an automatic test system.
