GE PEDL1000-57941101 Liquid Cooled IGBT Transistor Bridge, 690V 1000A

Description

3. Key Technical Specifications

4. Product Introduction

The GE PEDL1000-57941101 is a liquid-cooled IGBT-based transistor bridge module rated 690 V AC / 1000 A. It serves as a building-block power stage for high-power inverters in GE Power Conversion PECe-controlled systems, including MV3000 variable-speed drives, marine propulsion, and selected wind-turbine converters.

This specific variant includes Stäubli RMI16 quick-release coolant connectors, an integral cooling fan for the DC capacitor bank, and a conformally coated DIBe board for improved environmental resistance. It is designed for installation in a liquid-cooled DELTA mounting frame and requires proper PECe control, cooling system integration, and fusing to operate within ratings.

5. Installation & Configuration Guide

Stage 1: Pre-Installation Preparation (15–30 min) ⚠️ Safety First: This is a high-power, high-voltage module. Isolate all AC and DC sources. Lock out/tag out the entire drive system. Confirm residual DC-link voltage is below 50 V before any work. Drain and isolate the coolant circuit. Wait for surfaces to cool. Tools Required: ESD wrist strap, appropriate lifting equipment (module weighs 98 kg), torque tools for M10 studs, multimeter, coolant system pressure gauge, smartphone for photos. Data Backup: Photograph existing module orientation, coolant hose routing, power cable terminations, and control ribbon connections. Record PECe software configuration and any custom trip levels.

Stage 2: Removing the Old Module (20–40 min)

1. Confirm all power and coolant are isolated and residual energy is discharged.
2. Disconnect control ribbons (PL1, PL3) and any voltage-monitor connectors.
3. Disconnect AC and DC power cables from the M10 studs. Label each phase.
4. Disconnect Stäubli RMI16 coolant connectors and drain residual fluid.
5. Release mechanical locks and slide the module out of the DELTA frame using proper lifting aids. ⚠️ Inspect the mounting guides and backplane interfaces for damage or debris.

Stage 3: Installing the New Module (30–45 min)

1. Verify the module is marked PEDL1000-57941101 and matches the required variant (integral fan + coated DIBe).
2. ESD-protect and carefully slide the module into the lower guide plate and upper cross member of the liquid-cooled DELTA frame until fully seated.
3. Reconnect AC and DC power cables to the M10 studs using the correct high-temperature cable and torque values.
4. Connect the Stäubli RMI16 coolant lines. Verify correct flow direction and no leaks at 3 bar maximum working pressure.
5. Reconnect control ribbons and voltage-monitor connectors. Self-Checklist: [ ] Module fully seated [ ] Power cables torqued [ ] Coolant connected and leak-free [ ] Control ribbons locked.

Stage 4: Power-On & Testing (45–90 min) Pre-Power Check: Verify coolant flow at 25 L/min and inlet temperature ≤60 °C. Check insulation resistance and absence of shorts on power terminals.

1. Apply control power only and confirm DIBe / PECe communication.
2. Energize the DC link under controlled conditions and verify voltage monitoring.
3. Perform low-power functional tests per the PECe commissioning procedure.
4. Gradually increase load while monitoring heatsink temperature (90 °C warning / 95 °C trip), current, and losses. ⚠️ Troubleshooting Note: Excessive temperature or over-current trips usually indicate insufficient coolant flow, incorrect PWM settings, or improper PECe configuration. Refer to the official MV DELTA and PECe manuals before any adjustment.

6. Frequently Asked Questions (FAQ)

Q: Can this module be hot-swapped? No. The PEDL1000 is a high-power liquid-cooled stage. Removing or inserting it under power or with coolant pressurized creates serious arc-flash and fluid-hazard risks. Full isolation is mandatory.

Q: Is the PEDL1000-57941101 still in active production? These modules are manufactured/remanufactured under license by Avid Controls for GE Power Conversion systems. Availability is limited and application-specific. Confirm exact variant compatibility before ordering.

Q: What is the difference between PEDL1000-57941101 and the -47941101 version? The -57941101 includes the integral DC-capacitor cooling fan plus a conformally coated DIBe board. The -47941101 has the fan but no conformal coating on the DIBe. Confirm which version your system requires.

Q: What coolant is required? An ethylene-glycol/water mix compatible with the materials used in the module. Flow must be maintained at 25 L/min with inlet temperature ≤60 °C and maximum pressure 3 bar. Incorrect coolant or flow will cause rapid thermal trips or permanent damage.

Q: Does replacing this module require PECe software changes? Often yes. Certain operating limits that were previously set in older controllers must now be configured in the PECe code. Always verify and document the control parameters against the official PECe and MV DELTA manuals.

Q: Why is the price significantly lower than original OEM list? These are genuine surplus or licensed new units. They have never been installed in a running system but are no longer supplied through standard GE production channels. Full functional testing and warranty are provided.

Q: What fusing is recommended? For 1.1× overload at 600/690 V AC: Bussmann 170M6116 or equivalent Ferraz. Exact selection depends on starting frequency, ambient conditions, and parallel module count. Consult the application-specific fusing guidelines before energizing.
