25B-B048N104 Brand New Ser A 11KW 15HP AC Drive 25BB048N104
PRODUCT DETAILS
25B-B048N104 — 525 Series AC Drive, 240V Three-Phase, 15 HP / 11 kW, Embedded EtherNet/IP
The 25B-B048N104 is a 525 series drive rated at 15 HP / 11 kW Normal Duty (10 HP / 7.5 kW Heavy Duty), accepting 200–240V AC three-phase input and delivering 48.3A output current in a Frame E housing. It carries the full 525 platform feature set at this higher current rating — embedded EtherNet/IP, hardwired Safe Torque Off, and sensorless vector control with economizer — without a factory-installed filter.

Higher Current at 240V — Why Frame E Earns Its Size
At 48.3A on a 240V supply, this drive sits well into the larger frame sizes of its platform — covering pumps, fans, and conveyor drives in the 10–15 HP range where the supply available is 240V three-phase rather than 480V. The larger frame accommodates the thermal demands of this current level while retaining the same modular detachable control module design used across the smaller drives in the family, meaning commissioning, parameter access, and HIM compatibility carry over consistently regardless of frame size.
Economizer mode, available alongside sensorless vector control, automatically reduces motor flux at light load conditions — a meaningful efficiency gain on variable-torque loads like fans and centrifugal pumps that spend significant time running below full load. Embedded EtherNet/IP and hardwired STO being standard at this frame size, rather than optional add-ons, reflects that this power class typically goes into machines already built around networked, safety-integrated control architectures.
FAQ
Q: Is an external EMC filter required for CE-compliant installations?
Yes, on this no-filter configuration. An appropriately rated external filter should be added if the installation requires CE EMC compliance, or a filtered variant of this drive should be specified instead.
Q: What does economizer mode actually save, and when should it be used?
Economizer reduces motor magnetizing current at light load, lowering energy consumption on loads that run below full torque for extended periods — centrifugal pumps and fans benefit most; constant-torque loads see less benefit and shouldn't rely on it as the primary efficiency strategy.
Q: Does hardwired STO require a safety PLC to function?
No. The hardwired Safe Torque Off inputs can be driven directly by a standard safety relay's output contacts — a safety PLC isn't required unless the broader machine safety architecture calls for one.
Q: Can this drive's control module be swapped to another 525 drive of a different frame size?
The detachable control module is designed for cross-frame compatibility within the platform in many cases, simplifying spare parts handling — verify the specific source and destination frame combination against the platform's compatibility documentation before relying on this for a field swap.
