Product Introduction
 

XL-3003DZ-W Small Current Low Power Factor Standard Power Source Designed according to standards such as "JJG 597-2005 Verification Regulations for AC Energy Meter Verification Devices" and "JJG 597-202x Verification Regulations for AC Energy Meter Verification Devices." The current JJG 597-2005 standard has a low-end current measurement of 10mA and a low-end power factor test of 0.5. Compared to JJG 597-2005, the new JJG 597-202x standard requires a low-end current measurement of 0.3mA and a low-end power factor test of 0.25. The XL-3003DZ-W has an accuracy of 0.02%, suitable for power departments, enterprises, and research institutions in the power system that need to measure and verify small current and low power factor metering performance. It is also suitable for other occasions requiring high-precision standard signal sources for small current and low power factor measurement and verification. This device features high safety, ease of operation, a large touchscreen for control and display, and remote control capabilities.

Main Functions
