Model Definition

• 0-54341: Base part number (M Rectifier Suppressor)

• -1: Identical twin board (0-54341-1, same function/specs)

• -21: Higher-power variant (different component rating)

• Status: Obsolete; no direct OEM replacement

• Cross-Reference: 0-54341-1 (drop-in equivalent)

Technical Specifications

• Form Factor: Small PCB (≈120 × 80 × 20 mm)

• Weight: ≈0.2 kg

• Voltage Rating: Matches drive input (230/460/575 VAC)

• Current Rating: Up to 1200 A (rectifier suppression rating)

• Components: 4 green bead diodes, 3 large capacitors (red/green), 1 yellow polypropylene cap (zip-tied), 1 high-wattage resistor (standoff-mounted)

• Operating Temp: 0 °C to +55 °C

• Mounting: Edge-mounted via 6-screw silver terminal block

Interfaces & Communication

• Drive Side: Screw-terminal block (6 positions) for AC line and rectifier bridge connections

• Internal: Hardwired to drive power section; no external communication ports

Key Features

1. Voltage Spike Suppression: Protects rectifier diodes and SCRs from transients/inductive kickback

2. Compact Snubber Design: Small form factor for tight drive enclosures

3. Heavy-Duty Components: High-wattage resistor and rugged capacitors for industrial abuse

4. Easy Replacement: Direct bolt-on for fast field service

5. Drop-In Equivalent: 0-54341-1 is functionally identical

Application

• Drive Systems: AutoMax, MaxPak, FlexPak 3000/6000 AC/DC drives

• Industries: Steel, paper, mining, cranes, conveyors, machine tools

• Use Case: Primary rectifier protection in high-current drive cabinets

Compatibility

• Compatible Drives: AutoMax 100–2000 HP, MaxPak DC drives, FlexPak 3000/6000

• Input Voltages: 230 VAC, 460 VAC, 575 VAC

• Current Range: 500–1200 A drives

Critical Notes

• Function: This is a snubber/suppressor board, not a memory or control board

• Replacement: Use 0-54341-1 if original fails (same specs, direct swap)

• Availability: Scarce new; refurbished is common for legacy drive maintenance
