Descripción del producto

The HT***0 product line, which includes HT***0, HT***2, HT***6 and HT***4, is a programmable DC power supply family that features high accuracy, high stability and low noise with independently operative 3 channel outputs.

With the embedded**-Bit digital to analog converter, which controls output voltage/current, and **-Bit analog to digital converter, which reads output voltage/ current and high accuracy voltage reference resources, users attain precise and output figures.

The HT***0 is controlled by high-end microprocessor. Equipped with RS***2C, USB and GPIB interfaces (optional), and with its compatibility with SCPI commands (Standard Commands for Programmable Instruments), it fulfills users’ needs extensively. The HT***0 also achieves higher accuracy by its software calibration, which avoids errors caused by manual operations.

In terms of over voltage/current protection (OVP/OCP), the HT***0 rapidly detects a problem by utilizing a combination of software configuration and hardware detection, which ensures connected objects against damages if any problem occurs.
