Products Description
The HMSLQ-3000A/50V DC High-Current Generator consists of a rectifier transformer and a rectifier unit. It employs a 6-pulse thyristor (SCR) rectifier circuit and achieves continuous adjustment of DC current and voltage through phase-shift voltage regulation. The system features constant-voltage and constant-current control functions. The main controller utilizes our company's latest dedicated trigger board, ensuring high control precision and excellent symmetry between positive and negative pulses. The equipment offers comprehensive protection functions, strong interference resistance, high reliability, simple operation, and a high degree of automation, and complies with IEC international standards and relevant industry standards.
