IS210BPPCH1AD | GE Mark VIe BPPC Board | In Stock

Description

Product Introduction

The GE IS210BPPCH1AD is a VMEbus power supply board from the Mark VIe Speedtronic series, purpose-built to provide regulated DC power to the Mark VIe control system backplanes. This board converts the plant’s nominal 125 VDC bus (typically from battery-backed DC supplies) into the clean, regulated voltages required by processor boards, I/O modules, communication interfaces, and field devices. The “AD” suffix indicates a maximum environment conformal coated board with the highest level of moisture, chemical, and particulate protection available, combined with the H1A revision features.

What sets the BPPCH1AD revision apart is its robust input filtering, wide input voltage tolerance (100–150 VDC), efficient operation (90% typical), comprehensive diagnostics including voltage monitoring, current monitoring, and temperature sensing, and the premium-grade urethane conformal coating that provides maximum protection in the harshest operating conditions. The board delivers 5 VDC at up to 20 A for logic circuits, ±12 VDC at 2.5 A for auxiliary circuits, and 24 VDC at 3.5 A for field I/O—all with low ripple for stable operation. For system integrators requiring a reliable, cost-effective power solution with maximum environmental protection in the most aggressive environments, this board is the ultimate OEM solution.

Key Technical Specifications

Key Selling Points & Differentiators

• Maximum Environment Coating Advantage: The “AD” suffix provides the thickest, most robust premium urethane coating (0.10–0.18 mm) rated for continuous exposure to high humidity, salt fog, chemical vapors, and airborne particulates. This is the ultimate protection variant for offshore platforms, coastal installations, desalination plants, chemical processing, pulp and paper mills, and mining operations.
• Multiple Output Rails: 5 V, ±12 V, and 24 V outputs—supplies all Mark VIe backplane power requirements from a single module.
• Wide Input Range: Accepts 100–150 VDC, covering typical plant battery voltages and fluctuations.
• Comprehensive Diagnostics: Voltage, current, temperature, and health monitoring for proactive maintenance.
• Comprehensive Protection: Foldback current limiting, overvoltage clamping, and thermal shutdown.
• Efficient Operation: 90% efficiency—balances cost and performance for standard configurations.
• 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 using magnification and UV light.
• 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. No clones, no refurbished units with unknown repair history.
• Pre-Shipment Capacitor Reform: For units stored more than 12 months, we perform a controlled capacitor reforming procedure to prevent inrush failures.

Frequently Asked Questions (FAQ)

Q: What does the “AD” suffix mean on IS210BPPCH1AD?

A: The “AD” indicates maximum environment conformal coating combined with the H1A revision. Specifically, it means the board has a premium-grade urethane conformal coating (0.10–0.18 mm) applied to the entire PCB assembly for the highest level of moisture, chemical, and particulate protection, along with all H1A features (20 A capacity, 90% efficiency, ±12 V outputs). The coating adds protection; the H1A features provide reliable power capability.

Q: What is the difference between IS210BPPCH1AC and IS210BPPCH1AD?

A: Both have heavy and maximum coatings respectively. The AC has heavy urethane/acrylic coating (0.05–0.13 mm); the AD has maximum premium urethane coating (0.10–0.18 mm). The AD provides the absolute highest level of protection for the most severe environments—offshore with continuous salt spray, chemical plants with corrosive vapors. For severe but not extreme environments, AC is sufficient.

Q: What is the difference between IS210BPPCH1A and IS210BPPCH1AD?

A: The H1A is non-coated; the H1AD has maximum environment conformal coating. The coating protects against humidity, salt fog, and chemical vapors. If your cabinet is in a coastal area, offshore platform, or extreme environment, the AD variant is strongly recommended. In a clean, climate-controlled room, the H1A is sufficient and costs less.

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

A: Good question. The coating adds about 0.15 mm to the board thickness, which does not affect VME slot fitment—clearances are designed for it. Power delivery, efficiency, ripple, and protection thresholds are identical to the non-coated H1A. Do not remove the coating or scrape it off—it voids the warranty and compromises protection.

Q: Can I use this board with 24 VDC or 48 VDC input instead of 125 VDC?

A: No. The BPPCH1AD is specifically designed for 125 VDC nominal input (100–150 VDC range). Using lower voltages will not produce the required outputs—the converter needs at least 90 VDC to regulate properly. Using higher voltages (above 150 VDC) will damage the input stage.

Q: Is this board hot-swappable?

A: No. The Mark VIe VME backplane does not support live insertion of power boards. You must de-energize the entire rack, wait for all LEDs to extinguish, and discharge the input bus capacitors (use a resistor, not a short). We’ve seen technicians try to pull a BPPC with the rack still powered—it arced across the backplane pins and took out neighboring boards.

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

A: We stock these on the shelf—usually ship within 24 hours of order placement and payment confirmation. 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 (two BPPC boards in parallel with diode isolation). The H1AD can be used in those configurations, but you must ensure your backplane supports the OR-ing diodes. If your SIL system uses IS220BPPC variants, check the diode configuration first. We can help verify compatibility.

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

A: If the board is electrically functional (passes our QC test) but doesn’t clear your fault, we’ll accept a return within 30 days provided the board shows no physical damage, no blown fuses, and no signs of overvoltage stress. We do charge a 15% restocking fee if the fault was due to a downstream short circuit or incorrect input voltage. We’ll work with you over the phone to diagnose the issue before we ship.
