Key Differentiator: The DS2020PDMAG6 offers the highest power capacity, most extensive I/O, and dual redundant inputs in the PDM series—a complete power and monitoring solution for the largest turbine control systems.

Selection Suggestions

1. Calculate Total Power – Sum power requirements of all connected devices; total must not exceed 800W.

2. Determine Output Configuration – Identify required voltage rails (24V, ±15V, 5V, 48V) and per-channel current needs.

3. Assess I/O Requirements – Use extensive integrated I/O for local monitoring; for ultra-large systems, supplement with separate I/O modules.

4. Plan Redundancy – Utilize dual input configuration for critical applications requiring uninterrupted power.

5. Check Cabinet Depth – Extended 85mm depth requires adequate clearance.

6. Firmware – Requires Mark VIe Toolbox v7.5 or higher for full diagnostic and I/O features.

Precautions

• ESD Protection – Use wrist strap and anti-static handling for sensitive I/O components.

• Power Sequencing – Apply control power before enabling main inputs (both redundant inputs).

• Per-Channel Fusing – Use specified fuse ratings only; never bypass protections.

• I/O Wiring – Use shielded twisted-pair for analog inputs; observe polarity for digital I/O.

• Grounding – Direct earth lug to system ground with 16 mm² wire; avoid daisy-chaining.

• Fan Maintenance – Dual redundant fans with speed monitoring; replace if speed drops below 80%.

• Capacitor Inspection – Check for bulging/leakage every 6 months; clean filters quarterly.

• Commissioning – Verify all outputs under full load; test all I/O with dummy devices before field connection.

• Redundant Input Testing – Test automatic failover by sequentially disabling each input.

• Firmware – Use only GE’s official JTAG tool for updates.
