THYRISTOR BASED DC POWER SOURCE

ZD5-1200 EJ

The Thyristor-Based DC Power Source is a reliable and efficient solution designed to deliver precise and stable DC output for demanding industrial applications. Built with advanced SCR (Silicon Controlled Rectifier) technology, it provides smooth and consistent control of welding current, ensuring excellent arc stability and high-quality welds. The power source offers smooth and stable output performance even under varying load conditions, making it ideal for a wide range of welding processes such as SMAW, TIG, and MIG (with external control). It operates with high efficiency, minimizing power losses and maximizing energy savings during continuous operation.

Designed with a rugged and durable construction, this unit performs reliably even in harsh industrial environments. The user-friendly control panel features digital meters for accurate voltage and current monitoring, ensuring easy operation and precise parameter control. Safety is a key focus, with in-built protection systems against over-voltage, over-current, and overheating to safeguard both the operator and the equipment.
