IC693PWR330H Power Supply: Cost-Efficient Power for Series 90-30
The IC693PWR330H is a high-capacity AC/DC input power supply engineered for the GE Fanuc Series 90-30 PLC platform. As the leftmost-slot module in a baseplate, it conditions facility power into the regulated rails that every logic and I/O module depends on. Because a single supply feeds the entire rack, its efficiency and hold-up behavior directly influence uptime cost across the panel. This revision H unit accepts 120/240 VAC or 125 VDC nominal input, giving integrators flexibility when retrofitting existing DC-backed control rooms or standard AC-fed cabinets.

Technical Specifications of the IC693PWR330H
- Nominal input: 120/240 VAC or 125 VDC, covering mixed plant power environments.
- AC input range: 85 to 264 VAC for wide tolerance to brownouts.
- DC input range: 100 to 300 VDC for DC-backed control systems.
- Input power: 90 VA (AC) or 50 W (DC), minimizing feeder loading.
- 5 VDC output: 30 W maximum at 5.0 to 5.2 VDC for logic backplane.
- Relay 24 VDC output: 15 W maximum at 24 to 28 VDC.
- Isolated 24 VDC output: 20 W maximum at 21.5 to 28 VDC for field devices.
- Hold-up time: 20 ms minimum, riding through short line disturbances.
- Inrush current: 4 A peak, 250 ms maximum, easing breaker coordination.
- Operating temperature: 0 to +60°C ambient.
Cost Implications of Each Rated Parameter
Each specification maps to a measurable operating cost. The 85 to 264 VAC input range reduces the need for external conditioning equipment, trimming installation expense. A 20 ms hold-up time prevents nuisance shutdowns during brief sags, avoiding restart labor and scrap. The isolated 24 VDC output at 20 W eliminates a separate field supply, saving panel space and wiring cost. Meanwhile, the 4 A peak inrush limit protects upstream breakers from nuisance tripping, which lowers maintenance callouts. Finally, the 0 to +60°C rating allows dense cabinet layouts without added cooling hardware.

Installation and Integration Notes
Mount the IC693PWR330H in the leftmost slot of the Series 90-30 baseplate; this position is mandatory for backplane power distribution. Verify input wiring matches the selected nominal voltage before energizing. This part has been discontinued by the manufacturer. Migrate to PACSystems RX3i (IC695 series); we stock remaining new and refurbished units. For DC operation, ensure the 100 to 300 VDC source is within range and properly fused. Allow adequate clearance for the 0 to +60°C ambient rating.
Reliability and Maintenance
Inspect the supply periodically for dust accumulation and secure terminal connections. Thermal stress is the primary wear factor; keeping cabinet ambient below +60°C extends service life. The 20 ms hold-up time and 4 A inrush limit reduce electrical stress on downstream modules. Since the IC693PWR330H is discontinued, maintain spare units to avoid unplanned downtime costs.
