One unit drives both 3KW (400V) and 6KW (400/800V) UV lamps. Drop-in replacement for Alfa Laval 9012146-01 in PureBallast BWTS — no wiring changes, no software updates, no HMI reconfiguration.
Replaces: Alfa Laval 9012146-01 / LPS M3-6 (all versions including the latest v4) · Compatible with PureBallast 3.1 & 3.2

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.

Why Fiver Electronic Technology?
28 Years of UV Power Electronics
Established in 1996, Fiver Environment Group Co., Ltd. has been designing and manufacturing UV ballasts and lamps for nearly three decades. Our product range spans 4W to 60,000W — from small air purification units to industrial-scale water treatment systems. The LPS-DP is not a reverse-engineered copy; it is an original design leveraging our deep expertise in medium-pressure mercury vapor lamp drivers.
We Make Both the Lamp and the Ballast
Fiver already manufactures the replacement UV lamps for PureBallast systems (9007810-80, 9009521-80, 58203480, 579367-98). By developing the LPS-DP, we now offer the complete lamp + ballast package — designed and tested together. This eliminates the interface compatibility risk that exists when buying a ballast from one supplier and a lamp from another.
70+ Patents, 20,000 m² Facility, Global QC
Our 20,000 m² production facility in China houses complete vertical integration: PCB assembly, power electronics testing, thermal cycling, and final QC. Every LPS-DP unit undergoes: (1) component-level incoming inspection, (2) 72-hour full-load burn-in test at maximum power in both 3KW and 6KW modes, (3) final parameter verification (ignition voltage, operating frequency, protection trip points). We hold ISO 9001, CE, and UL certifications.
24-48 Hour Global Port Delivery
We maintain stock at distribution hubs in Rotterdam, Singapore, Dubai, and Houston. Standard delivery to any major port worldwide is 24-48 hours. Emergency same-day dispatch is available for critical downtime situations. Compare this to OEM lead times of 4-8 weeks.
Complete Your Spare Parts Package
The LPS is just one component in the PureBallast UV system. Fiver offers the complete range of replacement parts:

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.
