Programmable DC Power Supplies

The CSP series Programmable DC Power Supply is upgraded and developed on the basis of iDealTek-Electronics' mature IGBT high frequency switching power topology and all-digital signal control loop. Featured with high precision, low ripple and fast response speed.
The Programmable DC Power Supply is different from the traditional DC power supply that can only control the output voltage and current values. The programmable DC Power Supplies can realize the programming of multiple parameters through adding the microprocessor unit with built-in control program, such as parameters like operating time, output rise time, protection response time, OVP and OCP etc. All can be set and programmed.
At the same time, the microprocessor unit also adds more functions to the power monitoring system, which can realize the query of the historical data of the test results, making the programmable DC power supply the best choice for laboratory test, production line manufacturing test, photovoltaic plate aging test and various cutting-edge applications with Programmable DC power supplies.

This series of Programmable Power Supplies have a total of 4 standard rated power levels, ranging from 1KW Desktop Programmable Laboratory power supplies to 3KW / 6KW / 10KW Rack-mounted Programmable DC power supplies. The maximum output voltage ranges from 600V to 1000V under different rated powers.

Beautiful appearance design with small and compact size, the whole series power supplies adopt silicone buttons, stepless knobs and LCD display on control panel layout. The output voltage, current, start / stop time, output rising rate, OVP, OCP and other parameter setting programming and reading of the Programmable Power Supplies can be easily and quickly completed through the front panel man-machine interface, up to 5 digits of high-precision programming and monitoring levels make the measurement results of the programmable DC power supply accurate and reliable, almost no need to use external power meters.

At the same time, the whole series of programmable DC power supplies are equipped with RS485 interface as standard, following the MODBUS-RTU international protocol, which can realize remote control programming, test results save and uploading to the master unit and status monitoring of the power supply.
