IS215VCMIH2C | GE VCMI Power Supply | Original Packaging

Description

Product Introduction

The GE IS215VCMIH2C is a VMEbus primary 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 (typically from battery-backed DC supplies) into the clean, regulated voltages required by processor boards, I/O modules, communication interfaces, and field devices. The H2C revision features maximum current capacity, advanced diagnostics, and improved efficiency.

What sets the VCMIH2C revision apart is its robust input filtering, wide input voltage tolerance (100–150 VDC), efficient operation (93% typical), advanced diagnostics including voltage monitoring, current monitoring, temperature sensing, and predictive health monitoring. The board delivers 5 VDC at up to 32 A for logic circuits, ±12 VDC at 4.5 A for auxiliary circuits, and 24 VDC at 5.5 A for field I/O—all with ultra-low ripple for stable operation. Advanced features include input transient protection, output overvoltage and overcurrent protection, and comprehensive status monitoring. For system integrators requiring maximum capacity, high-performance primary power with advanced diagnostics for the most heavily loaded Mark VIe systems, this board represents the ultimate OEM power solution.

Key Technical Specifications

Key Selling Points & Differentiators

• Maximum Current Capacity: 32 A on 5 V rail—supports the most heavily loaded backplanes with multiple high-power processor and I/O boards.
• Highest Efficiency: 93% efficiency—lowest heat generation in the series.
• Multiple Output Rails: 5 V, ±12 V, and 24 V outputs—supplies all backplane power requirements.
• Ultra-Low Ripple: <20 mV peak-to-peak—ensures stable operation of sensitive electronics.
• Enhanced Transient Protection: 2,000 V surge withstand—superior protection from plant electrical disturbances.
• Advanced Diagnostics: Voltage, current, temperature, and health monitoring with predictive indicators.
• Predictive Health Monitoring: Capacitor aging estimation and fan health monitoring.
• Comprehensive Protection: Foldback current limiting, overvoltage clamping, and thermal shutdown.
• 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.
• 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 IS215VCMIH2C and IS215VCMIH2B?

A: The H2C has significant improvements: higher 5 V current (32 A vs. 30 A), higher auxiliary currents (4.5 A vs. 4 A, 5.5 A vs. 5 A), higher efficiency (93% vs. 92%), lower ripple (<20 mV vs. <25 mV), and fan health monitoring. The H2C also requires Mark VIe Toolkit v7.0 or higher vs. v6.5 for H2B. If you need maximum capacity and advanced diagnostics, choose H2C.

Q: What is the difference between IS215VCMIH2C and IS215VCMIH2D?

A: The H2D revision typically includes enhanced diagnostics or minor performance improvements. The H2C is the base revision for the maximum performance series. Check your existing board—if you have H2D, verify compatibility. In most cases, H2C and H2D are interchangeable, but confirm with the board’s firmware requirements.

Q: What is the benefit of the 93% efficiency?

A: At 93% efficiency, the VCMIH2C generates approximately 42 W of heat at full load vs. 45 W at 92% and 50 W at 91%. This difference is significant in tightly packed cabinets and can extend the life of all components in the system.

Q: What is the predictive health monitoring feature?

A: The VCMIH2C continuously monitors capacitor aging, fan health, and overall power supply health. It estimates remaining component life based on temperature and operating hours, enabling proactive maintenance planning.

Q: What is the benefit of the 2,000 V transient protection?

A: The 2,000 V surge withstand provides superior protection from voltage spikes caused by lightning strikes, switching transients, or other plant electrical disturbances.

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

A: No. The VCMIH2C is specifically designed for 125 VDC nominal input (100–150 VDC range). Using lower or higher voltages will damage the board or fail to regulate properly.

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 rack and discharge capacitors before removal.

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.

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 H2C 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. We’ll diagnose with you before shipping.
