- Manufacturer: Advanced Energy / AEG Power Solutions
- Series / Model: Thyro-A / Thyro-A 2A 400-100 (e.g., H3, RLP3, H RLP3 variants)
- Device Type: 2-Phase Digital SCR Thyristor Power Controller (400 V AC / 100 A)
Advanced Energy Thyro-A 2A 400-100 SCR power controllers are industry-leading solid-state switching devices engineered for precise control of electrical heating elements, industrial furnaces, dryers, and thermoforming equipment. Operating via phase-angle or full-wave burst firing modes, they provide smooth power delivery up to 100 A.
Operating under high current loads and thermal stress inside control cabinets can cause SCR power module degradation, gate driver stage failure, primary switch-mode supply breakdown, or loss of bus communication. Faults typically present as uncontrolled runaway heating, shorted output phases, persistent Error LED conditions, or loss of command response.
What we repair on Thyro-A 2A 400-100 controllers:
-
Power Stage & SCR Modules: Testing, replacement, and recalibration of damaged thyristor modules, snubber protection networks, and high-speed semiconductor fuses.
-
Gate Driver Electronics: Component-level repair of optocouplers, gate transformers, and pulse shaping circuits controlling the SCR gates following output short circuits.
-
Main Control Board & Sync Circuits: Servicing of microcontrollers, mains zero-crossing detection circuits, and precision True RMS current/voltage sensing frontends.
-
Internal Power Supply Unit: Complete recapping, replacement of dried-out capacitors, PWM ICs, and auxiliary power rails.
-
Analog Inputs & Bus Interfaces: Diagnostics and repair of 0–10 V / 4–20 mA setpoint control inputs as well as optional fieldbus cards (Profibus, PROFINET, Modbus).
Benefits of our repair service:
-
Substantial Cost Reductions: Servicing a 100A digital SCR controller is far more economical than purchasing a brand-new unit.
-
Retain Thyro-Tool Configurations: Hardware-level repair preserves custom firing modes (TA/VAR), current limits, and load monitoring thresholds intact.
-
Proactive Overhaul: Thermally stressed components, electrolytic capacitors, and silicone thermal interface materials are renewed to guarantee long-term reliability under full 100A continuous load.
