Case Study:
A Texas gas power plant reduced unplanned outages by 50% after deploying IS220PSVOH1B in dual – redundant mode. The module’s fast transient response (≤5 ms) prevented voltage dips from tripping the turbine, saving $1.5M annually in lost generation.

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.
