Product Specification
| High Light | 45.0Hz-500Hz ac power supply ，ac power supply for car stereo ，Electrical Power Meters | ||
Programmable and Remote Control: Advanced DC Power Supplies offer programmable features and remote control capabilities. They can be interfaced with computers or control systems through various communication protocols such as USB, Ethernet, or GPIB (General Purpose Interface Bus). This allows for automated testing, remote operation, and integration into larger test setups or manufacturing systems. Programmable DC Power Supplies often provide software interfaces or programming languages for creating custom test sequences and automating complex power profiles.
