- Mechanical Shock Resistance: Compliant with IEC 61131-2
Material Composition: High-temperature resistant PCB; high-power rectifier diodes; high-voltage resistors; safety fuses; isolation transformers; flame-retardant plastic insulating brackets.
Structural Features: Horizontal installation layout; separate high-voltage area and low-voltage area; partition insulation design; integrated fuse seat; wiring terminals divided into high-voltage and low-voltage areas.
Working Principle: Distribute the input three-phase high-voltage power to each power unit of the drive; convert part of high-voltage power into stable 24 V DC auxiliary power for control circuits; realize electrical isolation between strong current and weak current circuits.
Advantages & Highlights: Strict high-low voltage isolation; reliable over-current protection; stable auxiliary power output; compact structure; strong overload resistance.
Applicable Industries: Mining equipment, cement machinery, industrial fan, large pump unit, oil and gas industry, heavy industry transmission.
Installation Requirements: Install in the independent power compartment of the drive; strictly distinguish high-voltage and low-voltage wiring areas; tighten all power terminals; ensure insulation partitions are intact.
Usage Notes: Operate strictly within rated voltage range; do not replace fuses with non-specified specifications; cut off main power before maintenance; keep the board surface dry and clean.
