Topfer PL Series Programmable DC Power Supply/High accuracy, compact, high efficiency

The Topfer PL series is a programmable DC power supply featuring high accuracy, compact size, high efficiency, and excellent stability. It is widely used in various electronic devices. The wide-range programmable power supply comes with built-in RS232 and RS485, supporting the standard SCPI protocol, making it convenient for remote control and the construction of intelligent test platforms. The remote compensation terminals help to avoid issues of inaccurate testing caused by voltage drops across the leads.

18-bit/24-bit high-resolution accurate voltage and current readback functions, along with wide-range output characteristics, allow users to adjust the output voltage and current arbitrarily within the rated power range.

Programmable settings allow for more flexible operation, with the ability to set 0-10 groups of LIST.CYCLE ranges from 1 to 999,999 times. This makes it convenient for users to output different voltages and currents on a timer, while also being able to set the number of cycles. The unit features voltage and current slew rate functions; when these are set, the output will change according to the specified slew rate.

The output voltage and current have a wide range, with voltage ranging from 0-120V and output current up to 0-20A. Users can select the appropriate model based on their actual usage scenarios. The functional keyboard and encoder knob make it easy for users to operate flexibly.

Multiple protection features include overvoltage protection, overcurrent protection, overtemperature protection, overpower protection, short circuit protection, and reverse compensation line protection, ensuring that the power supply operates safely in a reliable environment.
