Supply and spare parts information
Original factory status: Standard production model, no suspension; Original factory delivery time 6–10 weeks
Core vulnerable spare parts:
Main control board: MC22-T (the brain of the entire machine, can be replaced separately)
Thyristor power bridge, cooling fan, buffer absorption capacitor
Alternative compatibility: The standard version of DRP-6T in the same series can be replaced by DRP-6T-H after program fine-tuning, but the lifespan in heavy-load conditions is slightly shorter
Market channels: New original equipment, refurbished second-hand available in stock, second-hand must verify the constant current and stable voltage accuracy and insulation withstand voltage
