Why Replace Your Alfa Laval LPS M3-6?
The Alfa Laval 9012146-01 (LPS M3-6) is the lamp power supply module used in PureBallast ballast water treatment systems. While reliable, it has a costly problem for shipowners and fleet managers:
Problem OEM pricing & lead times. Sole-source supply through Alfa Laval means premium pricing (often $8,000-12,000+ per unit) and 4-8 week lead times. When a UV ballast fails at sea, every day of downtime costs you.
The Fiver WBAF-440-6-600 solves the problem. One unit replaces the LPS M3-6 for both 3KW and 6KW systems — at 50-60% less cost than OEM, with 1-2 week delivery.

Frequently Asked Questions
Does the Fiver WBAF-440-6-600 directly replace the Alfa Laval 9012146-01 LPS M3-6?
Yes. The WBAF-440-6-600 is a direct drop-in replacement for the Alfa Laval 9012146-01 LPS M3-6 (all versions including v4). It matches the OEM form factor (381 × 241 × 97 mm), DIP switch addressing (1-16 via S3/S4), 25 kHz operating frequency, RS485 Modbus RTU (19200 baud, 8N1), and +24 VDC control signals. No wiring modifications, no software changes, no HMI reconfiguration.
How much money do I save switching to the Fiver WBAF-440-6-600?
Typically 50-60% less per unit than OEM Alfa Laval pricing. Additionally, the dual-power design means you stock one spare instead of two (3KW + 6KW), cutting inventory costs further. For a 10-vessel fleet with mixed systems, total savings can reach $80,000-130,000.
Can one unit really drive both 3KW and 6KW lamps?
Yes — this is the key advantage over OEM. The WBAF-440-6-600 is field-configurable: in 3KW mode it outputs 400V for 435mm
How fast can you deliver?
Fiver maintains stock for 1-2 week dispatch worldwide. OEM lead times are typically 4-8 weeks. For urgent vessel downtime, contact us for expedited shipping — we understand every day idle costs you money.
Will my PureBallast HMI and alarm system work the same?
Yes. The WBAF-440-6-600 communicates with your EC and LDC controllers via the same RS485 Modbus RTU protocol and I/O signals. All lamp status, alarm codes, and fault reporting display identically on the PureBallast HMI. Your crew operates the system exactly as before.
What warranty do you offer?
24-month warranty covering manufacturing defects and component failures under normal operating conditions — double the typical OEM warranty. Our engineering team provides remote technical support and worldwide installation guidance.
