- 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.
