IS215PMVDH1A | GE Mark VIe PMVD Board | In Stock

Description

Product Introduction

The GE IS215PMVDH1A is a VMEbus power supply module 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 into the clean, regulated voltages required by processor boards, I/O modules, communication interfaces, and field devices. The H1A revision features comprehensive diagnostics and balanced power capacity for standard configurations.

What sets the PMVDH1A revision apart is its robust input filtering, wide input voltage tolerance (100–150 VDC), efficient operation (90% typical), and comprehensive diagnostics including voltage monitoring, current monitoring, and temperature sensing. 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. Advanced features include input transient protection, output overvoltage and overcurrent protection, and status monitoring. For system integrators requiring a reliable, cost-effective power solution for standard Mark VIe configurations, this board is the direct OEM solution.

Key Technical Specifications

Key Selling Points & Differentiators

• Balanced Power Capacity: 20 A on 5 V rail—ideal for standard configurations without excess capacity.
• 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.
• 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 controlled capacitor reforming to prevent inrush failures.

Frequently Asked Questions (FAQ)

Q: What is the difference between IS215PMVDH1A and IS215PCMIH1A?

A: The PMVDH1A provides lower capacity (5 V @ 20 A vs. 25 A) and lower efficiency (90% vs. 91%). The PMVDH1A is designed for standard configurations with moderate power requirements. The PCMIH1A is designed for heavily loaded configurations requiring higher current capacity. Choose PMVDH1A for standard systems, PCMIH1A for high-density systems.

Q: What is the difference between IS215PMVDH1A and IS215PMVDH1B?

A: The H1B revision typically includes enhanced diagnostics or minor performance improvements. The H1A is the base revision. Check your existing board—if you have H1B, verify compatibility. In most cases, H1A and H1B are interchangeable, but confirm with the board’s firmware requirements.

Q: What is the benefit of the 90% efficiency?

A: Higher efficiency means less heat generation inside the cabinet. For a 400 W power supply, 90% efficiency generates approximately 40 W of heat vs. 44 W for an 89% efficient supply. This difference can impact cabinet temperature and component life in tightly packed cabinets.

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

A: No. The PMVDH1A 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 PMVD with the rack still powered—it arced across the backplane pins and took out neighboring boards. Don’t risk it.

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 PMVD boards in parallel with diode isolation). The H1A can be used in those configurations, but you must ensure your backplane supports the OR-ing diodes. If your SIL system uses IS220PMVD variants, check the diode configuration first. We can help verify compatibility.

Q: Does this board work with the newer Mark VIeS (SIL-rated) cabinets?

A: To be direct: no. The IS215PMVDH1A is not SIL-certified. It’s meant for standard Mark VIe industrial control. The SIL-rated systems use the IS220PMVD (with additional redundancy, diagnostic coverage, and separate safety shutdown path). Mixing them violates your site’s safety integrity level.

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—our goal is to get you running, not to ship boxes back and forth.
