More Information

Overview Manuals Input Outputs Supervision Application
  • Official type designation SPGU 240 A1
  • 80 to 265 V AC or DC input range
  • Isolated internal rails with voltage-deviation supervision

SPGU 240 A1 is ABB's plug-in relay power supply module.

The module accepts 80 to 265 V AC or DC and uses a transformer-connected, galvanically isolated flyback DC/DC converter to generate +24 V, ±12 V, and +8 V internal rails.

ABB documents the module in SPAG 330 C, SPAD 346 C, and SPAS 348 C protection-relay assemblies, with self-supervision for excessive secondary-voltage deviation.

Availability, condition, price, and shipping time for SPGU 240 A1 are confirmed during quotation.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
How can I confirm ABB SPGU 240 A1 SPGU 240 A1 suits my protection relay?
Verify relay model, type, supply, connector, fuse, internal rails, fit, and service manual.
Can ABB SPGU 240 A1 replace another SPGU module based only on input voltage?
No. Type, relay, pinout, fuse, rails, supervision, and mechanical installation must all match.
What should be checked before installing ABB SPGU 240 A1?
Confirm supply, voltage, polarity, fuse, connector, relay compatibility, grounding, clearances, and physical condition.
What checks follow installation of ABB SPGU 240 A1?
Verify the green indication, self-supervision, stable supplies, temperature, relay startup, and protection functions.
What should be inspected if ABB SPGU 240 A1 triggers supervision?
Check incoming supply, fuse, connector, relay load, voltage deviation, wiring, contamination, heat, and relay electronics.
Are cables, connectors, or the complete relay included with ABB SPGU 240 A1?
Treat it as the module only unless the quotation explicitly lists assemblies, accessories, or documents.
What information is needed to quote ABB SPGU 240 A1?
Provide relay model, label, connector photos, supply, fault, condition, quantity, and destination.
