Why Engineers Switch from San Ace 9HV to LWAD12038
4–8× Faster Delivery
40–55% Lower Landed Cost
Drop-in Candidate · Same Size Class
Drop-in compatibility: what matches and what to confirm
Mechanical match
The LONGWELL LWAD12038 matches the Sanyo Denki San Ace 9HV mounting pattern (M-mount, ISO 9001 plenum-fan footprint) per the mounting dimensions on the LONGWELL drawing. Inlet ring diameter, motor shaft height, and electrical termination box position are identical. In most retrofits no plate modification is needed — confirm the mounting dimensions against the LONGWELL drawing before ordering.
Electrical & control match
The LWAD12038 accepts the same 0–10 V analog speed reference, PWM (1 kHz), and Modbus RTU (RS485) control signals as Sanyo Denki San Ace 9HV. LONGWELL supplies its Modbus RTU register map with the fan so the BMS points can be re-mapped; the register addresses are not identical to the Sanyo Denki map.For ebm-papst-specific bus protocols (EC-Control), ask LONGWELL engineering for the integration options.
Performance match
The measured P-Q curve of every LONGWELL model is on its model page; we check your duty point against it before quoting.
Typical Applications
The LWAD12038 is widely deployed across BESS rack module, DCFC power conversion, telecom rack cooling. Common application categories include:
- BESS rack module
- DCFC power conversion
- Telecom rack
Particularly suited for BESS rack module + DCFC power conversion module cooling.
