Product Introduction
The 531X113PSFARG1 is a high-capacity power supply for the most demanding Mark V rack configurations, delivering 1600W—slightly more than the 1500W family—with a comprehensive feature set including load-sharing, remote sensing, diagnostic data logging, and USB log download. It’s built for critical turbine applications where every amp counts and power continuity is essential.
Compared to the 531X113PSFARG (non-1 revision), the “G1” version adds active power factor correction (upgraded from 0.95 to >0.99), extended hold-up from 50ms to 150ms, a modular fan cartridge with ball-bearing fans, and diagnostic data logging with USB download. The terminal assignment is identical—direct drop-in. No firmware changes required.

Frequently Asked Questions (FAQ)
Q: What’s the difference between the FARG1 and the 112 series AALG1?
Both deliver 1600W (66.6A) with 150ms hold-up and 5000-event logs. The FARG1 is from the 113 series, while the AALG1 is from the 112 series—they are essentially identical in specification. The 112 series may have slight variations in component sourcing, but functionally they are direct equivalents. You can use either as a replacement for the other.
Q: The Fault LED is red, but the DC OK LED is green. What’s happening?
Green DC OK means the 24V output is within spec. Red Fault indicates an internal warning—typically overtemperature (fan failure) or input voltage out of range. The data logger captures the fault, and the USB port allows quick log download for analysis. The diagnostic registers provide detailed fault type information.
Q: Can I run two FARG1 supplies in parallel for redundancy?
Yes—the FARG1 has OR-ing diodes and hardware load-sharing. Connect DC outputs together (+24V to +24V, 0V to 0V), connect load-share signal terminals together, connect remote sense terminals together, connect RS-485 terminals together (daisy-chain), and feed AC inputs from separate breakers. The supplies share the load within ±1%. Each supply has its own data log.
Q: Can I hot-swap the FARG1 while the rack is powered?
Yes, in redundant configurations (two supplies in parallel). In a single-supply config, pulling the supply shuts down the rack. If redundant, verify the OR-ing diodes are present before pulling one. The remote sense and load-sharing circuits automatically re-balance when you insert a new supply.
Q: What’s the expected lifespan of the FARG1?
The electrolytic capacitors are rated for 12,000 hours at 85°C. In a 40°C cabinet, the lifespan extends to about 18-22 years. The modular fan cartridge with dual ball-bearing fans is rated for 80,000 hours at 40°C (about 9.1 years). Replace the fan cartridge every 5-7 years proactively.
Q: What’s the lead time for a surplus unit?
We keep 2-3 units in stock. Domestic: 2-3 business days ground, overnight if ordered by 2 PM EST. International: 5-7 days via DHL, with customs potentially adding 1-3 days. We include a GE certificate of origin and commercial invoice with every shipment. Contact us if you need expedited shipping.
