GE IS220PSCAH1A 336A4940CSP9 Mark VIe Power Supply Module
Product Overview
The GE IS220PSCAH1A 336A4940CSP9 is a high-reliability power supply module designed as a critical component of GE’s Mark VIe control system, responsible for delivering stable and redundant power to I/O modules, controllers, and communication cards in industrial automation. As part of the IS220 Series, this module ensures continuous operation of mission-critical systems in power generation, oil & gas, and manufacturing, where unplanned downtime can lead to significant losses. The IS220PSCAH1A 336A4940CSP9 integrates seamlessly with other Mark VIe components, forming a robust power infrastructure that supports triple modular redundancy (TMR) and hot-swappable configurations.
Featuring a dual-input design (110/220 V AC), the GE IS220PSCAH1A 336A4940CSP9 converts AC power to regulated 24 V DC output, delivering up to 10 A current to power connected devices. Its advanced power conditioning circuitry includes overvoltage, overcurrent, and thermal protection, safeguarding sensitive electronics from electrical anomalies. The module’s rugged construction—with conformal coating and compliance with MIL-STD-810G—withstands extreme temperatures (-40°C to +70°C), vibration, and humidity, making it suitable for harsh environments like offshore platforms and power plant turbine halls.
In automation ecosystems, the IS220PSCAH1A 336A4940CSP9 serves as the power backbone, enabling redundant configurations where two modules operate in parallel: if one fails, the other seamlessly takes over, ensuring uninterrupted power. Its hot-swappable design allows replacement without system shutdown, a key feature for 24/7 operations. By combining high efficiency (up to 92%), robust protection, and redundant architecture, this module ensures the reliability of Mark VIe systems, supporting critical processes from turbine control to safety shutdowns.
