IS210BPPCH1AC | GE BPPC Power Supply | Original Packaging

Description

Product Introduction

The GE IS210BPPCH1AC 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 “AC” suffix indicates a heavy conformal coated board with enhanced moisture, chemical, and contaminant resistance for harsh environments, combined with the H1A revision features.

What sets the BPPCH1AC 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 thicker urethane or acrylic conformal coating that provides superior protection in harsh environments. 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 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 “AC” 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, desalination plants, and chemical processing facilities.
• 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.
• 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 “AC” suffix mean on IS210BPPCH1AC?

A: The “AC” indicates heavy conformal coating combined with the H1A 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 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 IS210BPPCH1A and IS210BPPCH1AC?

A: The H1A is non-coated; the H1AC 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 AC variant is strongly recommended. In a clean, climate-controlled room, the H1A is sufficient and costs less. If your existing board is coated, you must replace it with a coated board (AC) because the uncoated version will fail faster in that environment.

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

A: Good question. The coating adds about 0.1 mm to the board thickness, which does not affect VME slot fitment. Power delivery, efficiency, ripple, and protection thresholds are identical to the non-coated H1A. The coating only provides environmental protection. Do not remove the coating or scrape it off—it voids the warranty and compromises protection.

Q: What is the difference between IS210BPPCH1AC and IS2020LVPSG1A?

A: The BPPCH1AC provides lower capacity (5 V @ 20 A vs. 25 A) and includes ±12 V rails for auxiliary circuits. The LVPS provides higher capacity but may not include the same coating level. Choose BPPCH1AC for standard configurations requiring ±12 V with heavy coating. Choose LVPSG1A for higher capacity standard applications.

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

A: No. The BPPCH1AC 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 H1AC 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.
