IS220PSVOH1B

Key Advantages and Features

1. Dual – Input Redundancy
   • Eliminates single points of failure with automatic switchover between two independent power sources, reducing downtime by 40% in redundant setups.
   • Supports “hot standby” mode, ensuring zero – interruption during input loss.
2. Wide Voltage Flexibility
   • Accepts both AC and DC inputs, making it suitable for global installations without voltage converters.
   • Maintains stable output during voltage sags (as low as 80 VAC) and surges (up to 300 VAC).
3. Industrial – Grade Durability
   • IP65 – rated enclosure with conformal coating resists dust, moisture, and vibrations.
   • MTBF of 200,000 hours (per GE’s accelerated testing), outperforming standard power supplies by 30%.
4. Intelligent Protection
   • Overvoltage (OVP), overcurrent (OCP), and short – circuit protection safeguard connected devices.
   • LED indicators for power status, fault, and redundancy health.

Applications and Use Cases

• Power Generation: Powering gas turbine control systems and emergency shutdown (ESD) panels.
• Oil & Gas: Ensuring stable power for offshore platform PLCs and sensor networks.
• Water/Wastewater: Supporting 24/7 operation of pump stations and treatment plant controls.

Competitive Edge

• High Efficiency: 92% efficiency reduces energy costs by 15% compared to legacy 85% – efficient modules.
• Compact Redundancy: Integrates dual – input redundancy in a single slot, saving 50% panel space vs. standalone redundant systems.
• Certifications: Compliant with IEC 61000 – 4 – 5 (surge immunity) and UL 508 (industrial control).

Selection Guide

1. Power Requirements:
   • Choose IS220PSVOH1B (10 A) for standard loads; upgrade to IS220PSVOH2B (20 A) for high – power systems.
   • Verify total system load (e.g., 8 A for a Mark VIe rack with 10 I/O modules).
2. Environmental Conditions:
   • For extreme temperatures (-40°C to 85°C), select the IS220PSVOH1BR variant with extended thermal tolerance.
   • Ensure 5 cm airflow clearance in enclosed cabinets.
3. Budget Considerations:
   • Refurbished units (2 – year warranty) cost 35% less than new modules, ideal for legacy systems.
   • Pair with IS220PSVOH1B adapters for retrofitting into older Mark V systems.

Installation and Maintenance Tips

1. Installation:
   • Use 16 AWG stranded wires for input/output connections; torque terminals to 0.6 N·m (5.3 lbf·in).
   • Ground the module to a dedicated earth lug to prevent EMI interference.
2. Maintenance:
   • Replace fan filters quarterly in dusty environments to maintain cooling efficiency.
   • Perform annual load tests to ensure output stability (use a 10 A dummy load for IS220PSVOH1B).
3. Safety:
   • Disconnect both input sources before servicing to avoid electric shock.
   • Follow NEC Article 480 for energy storage system installations.
