1.Main Functions

1. Isolated auxiliary power generation for IGCT gate‑units Accepts wide‑range AC input and converts into multiple groups of stabilized, galvanically‑isolated DC power supplies. Supplies operating power to each IGCT gate drive unit inside the medium‑voltage power converter, ensuring reliable turn‑on / turn‑off triggering of high‑power IGCT power semiconductors.
2. High‑voltage electrical isolation between control side and power side Implements reinforced galvanic isolation between low‑voltage control circuit and medium‑voltage power stage. Blocks high‑voltage surge and common‑mode noise from power section, protects low‑voltage control electronics from medium‑voltage interference and damage.
3. Multi‑level built‑in hardware protection Integrates over‑voltage, under‑voltage, short‑circuit, and thermal‑overload protection. Shuts down output power automatically upon abnormal conditions to prevent gate‑unit burnout and power‑device failure, avoiding secondary damage to the medium‑voltage drive system.

1. System status monitoring and local fault indication Multiple LED status indicators on assembly front panel. Real‑time monitors input power, each channel output voltage and internal temperature. Visible fault indication for on‑site troubleshooting, helps maintenance staff quickly locate power‑supply‑related failures.More products: www.plcva.com
2. Internal signal conditioning & auxiliary interlock signal output Detects power‑supply health status, outputs hardware fault interlock signals to main drive control board. Triggers converter alarm or safe shutdown once gate‑unit power becomes abnormal, following medium‑voltage drive safety logic.
3. Integrated sub‑board modular structure Assembled with seven embedded sub‑boards. Supports partial sub‑board replacement for maintenance; improves serviceability for on‑site repair of large medium‑voltage converters.

Important note: This module cannot operate independently. It must work cooperatively with ACS1000 main control board, IGCT gate‑units, power cell stacks and cooling system to constitute a complete medium‑voltage frequency converter. It is not a general‑purpose PLC power supply.
