GE IS210AEPSG1AFC | VME Power Module | Fast Shipping

Description

Product Introduction

The GE IS210AEPSG1AFC is a VMEbus auxiliary power supply module from the Mark VIe Speedtronic series, purpose-built to provide regulated DC power to specific sections of the Mark VIe control system backplanes and field devices. This board converts the plant’s nominal 125 VDC bus into clean, regulated voltages for auxiliary circuits, analog I/O, and field loops. The “AFC” suffix indicates a heavy conformal coated board with enhanced moisture, chemical, and contaminant resistance for harsh environments, combined with the G1A revision features.

What sets the AEPSG1AFC revision apart is its robust input filtering, wide input voltage tolerance (100–150 VDC), multiple regulated output rails including ±15 V for analog circuits, and the thicker urethane or acrylic conformal coating that provides superior protection in harsh environments. The board delivers 5 VDC at 10 A for auxiliary logic, ±15 VDC at 2 A for analog circuits, and 24 VDC at 3 A for field loops—all with low ripple for stable operation. Advanced features include output overvoltage and overcurrent protection, thermal shutdown, and status monitoring. For system integrators requiring auxiliary power with enhanced environmental protection in aggressive installations, this board is the direct OEM solution.

Key Technical Specifications

Key Selling Points & Differentiators

• Heavy Conformal Coating for Extreme Environments: The “AFC” suffix provides a thicker, more robust coating (0.05–0.13 mm) that protects power electronics against high humidity, salt fog, and chemical exposure. This is the preferred variant for offshore platforms, coastal installations, and chemical processing facilities.
• Multiple Output Rails: 5 V, ±15 V, and 24 V outputs—supplies auxiliary, analog, and field power from a single module.
• ±15 V for Analog Circuits: Dedicated rails for precision analog I/O—ensures stable, low-noise operation.
• Wide Input Range: Accepts 100–150 VDC, covering typical plant battery voltages and fluctuations.
• Comprehensive Protection: Foldback current limiting, overvoltage clamping, and thermal shutdown protect downstream modules.
• Status Monitoring: Output voltage, current, temperature, and health indicators for proactive maintenance.
• Live Test Verified: Every board undergoes a 48-hour burn-in at full rated load with cycling input voltage. We log output voltages, ripple, thermal performance, and diagnostic thresholds. Coated boards are visually inspected for complete coverage, thickness consistency, and absence of bubbles, voids, or pinholes.
• 90-Day Warranty: Covers functional defects. If it fails under normal operating conditions, we replace it. No restocking fee for verified returns.
• OEM Traceability: All units come from audited surplus channels with original GE anti-static bags and serialized labels.
• Pre-Shipment Capacitor Reform: For units stored more than 12 months, we perform controlled capacitor reforming to prevent inrush failures.

Frequently Asked Questions (FAQ)

Q: What does the “AFC” suffix mean on IS210AEPSG1AFC?

A: The “AFC” indicates heavy conformal coating combined with the G1A revision. Specifically, it means the board has a thicker urethane or acrylic conformal coating (0.05–0.13 mm) applied to the entire PCB assembly for maximum moisture, chemical, and contaminant protection, along with all G1A features (multiple outputs, ±15 V analog rails, 88% efficiency). The coating adds protection; the G1A features provide auxiliary power capability.

Q: What is the difference between IS210AEPSG1AFC and IS210AEPSG1A?

A: The G1A is non-coated; the G1AFC has heavy conformal coating. The coating protects against humidity, salt fog, and chemical vapors. If your cabinet is in a coastal area, offshore platform, or harsh environment, the AFC variant is strongly recommended. In a clean environment, the G1A is sufficient and costs less.

Q: What is the difference between IS210AEPSG1AFC and IS2020LVPSG1A?

A: The AEPS provides lower capacity (5 V @ 10 A vs. 25 A) and includes ±15 V rails for analog circuits, which the LVPS does not provide. The AEPS is an auxiliary supply for analog and auxiliary circuits; the LVPS is a main system supply for backplane logic. Choose AEPS for analog/auxiliary power; choose LVPS for main system power.

Q: What is the ±15 V output used for?

A: The ±15 V output is specifically for powering precision analog circuits such as analog input boards (e.g., ISUCG, AEAB, AEDB) and analog output boards. These rails provide clean, regulated power for high-accuracy analog measurement and control. If your system includes these analog boards, you need ±15 V power.

Q: Does the heavy coating affect power delivery, efficiency, or protection?

A: No. The coating is applied after functional testing, so it does not affect the electrical characteristics. Power delivery, efficiency, ripple, and protection thresholds are identical to the non-coated G1A. The coating only provides environmental protection.

Q: Is this board hot-swappable?

A: No. The Mark VIe backplane does not support live insertion. You must de-energize the rack, wait for LEDs to extinguish, and discharge capacitors. We’ve seen technicians try to pull an AEPS with the rack still powered—it arced and damaged neighboring boards.

Q: What is the typical lead time for this part?

A: We stock these on the shelf—usually ship within 24 hours. For international orders, add 3–5 days for customs. If you need expedited (overnight air), coordinate with our logistics team.

Q: Does this board work with both Mark VIe and Mark VIeS (SIL-rated) cabinets?

A: Yes—with a caveat. SIL systems typically require redundant power supplies. The G1AFC can be used in those configurations, but ensure your backplane supports OR-ing diodes. We can help verify compatibility.

Q: What’s your return policy if this doesn’t fix my power-related fault?

A: If the board passes our QC test but doesn’t clear your fault, accept a return within 30 days provided no physical damage or overvoltage stress. We charge a 15% restocking fee if the fault was due to downstream short circuits or incorrect input voltage.
