Single-phase 60 Hz variable-frequency power supply
Since joining the WTO, China’s economy has integrated with the global market, creating opportunities for export-oriented electrical equipment manufacturers. Due to the lack of unified grid standards across different countries, the production of export products requires simulating the grid conditions of various nations while ensuring stability. In the past, systems utilizing voltage regulators for voltage adjustment, voltage stabilizers for voltage stabilization, and generators for secondary frequency conversion were widely adopted; however, these methods were gradually replaced by variable-frequency power supplies due to their high power consumption, significant noise levels, and poor stability. The AC60 programmable variable-frequency power supply is specifically designed and manufactured for voltage and frequency transformation testing of imported and exported electrical products. It can provide voltage and frequency outputs conforming to the grid standards of various countries, features digitally adjustable output voltage and frequency without discrete steps, delivers stable and pure waveforms, and effectively eliminates grid interference. This power supply is suitable for voltage and frequency transformation testing of export electrical products, as well as for conducting various precision tests in laboratories, metrology rooms, and other similar environments, or as a power source for 60 Hz equipment.
- Equipped with overvoltage, overcurrent, short-circuit, and overheating warning devices
- Controlled by a 16-bit microprocessor, featuring intelligent functionality and flexible, user-friendly operation.
