Description

Alfa Laval LPS M 3-6 Lamp Power Supply

Manufacturer: Alfa Laval

Country of Origin: Sweden

Product Type: High-Power Electronic Lamp Power Supply / Ballast Module

Marine Application: UV lamp power supply for Alfa Laval PureBallast Ballast Water Treatment Systems (BWTS).

---

Product Introduction

The Alfa Laval LPS M 3-6 Lamp Power Supply is a high-performance electronic ballast designed to operate high-power UV discharge lamps used in Alfa Laval PureBallast systems. It provides the controlled ignition voltage, operating current, and continuous power required for UV lamps that disinfect ballast water before discharge.

Unlike a conventional transformer, the LPS M 3-6 continuously regulates lamp performance, monitors operating conditions, and communicates with the control system to ensure reliable UV output under varying load conditions.

Marine operators depend on this module because the UV reactor cannot function correctly without a stable lamp power supply.

---

What Is the Alfa Laval LPS M 3-6?

The LPS M 3-6 is an electronic power conversion module that converts the vessel's AC supply into a controlled high-frequency output for UV discharge lamps.

Its responsibilities include:

• High-voltage lamp ignition
• Lamp current regulation
• Output power stabilization
• Lamp monitoring
• Internal fault detection
• Lamp error diagnostics
• Communication with the PureBallast control system
• Protection against overloads and abnormal operating conditions

Without this module, the UV lamps cannot generate the ultraviolet energy required for ballast water disinfection.

Common Problems & Troubleshooting

Like any high-power electronic ballast, the LPS M 3-6 may experience faults after years of continuous marine operation. Most issues originate from power fluctuations, component aging, excessive heat, or UV lamp degradation.

Common Problems

• Lamp fails to ignite
• UV lamp turns off after startup
• Internal ballast fault alarm
• Lamp error indication
• High temperature shutdown
• Fuse failure
• Burned power semiconductors
• Capacitor aging
• Output voltage instability
• Communication failure with controller
• Water ingress damage
• Connector corrosion
• PCB component failure
• Cooling ventilation blockage
• Intermittent operation

Basic Troubleshooting

Before replacing the module, marine engineers should verify:

• Incoming AC power supply
• Input fuse condition
• UV lamp condition
• Lamp cable continuity
• Connector tightness
• Cooling airflow
• Moisture inside enclosure
• Output voltage
• Internal alarm LEDs
• Communication wiring
• Grounding integrity

Many ballast failures are actually caused by defective UV lamps or damaged wiring rather than the power supply itself.

Preventive Maintenance Tips

Routine preventive maintenance greatly extends the operating life of the Alfa Laval LPS M 3-6.

Recommended maintenance includes:

• Clean cooling passages regularly.
• Keep ventilation openings free from dust.
• Inspect electrical terminals for corrosion.
• Replace damaged connectors.
• Verify output voltage during service.
• Inspect internal PCB for overheating.
• Replace aging electrolytic capacitors when necessary.
• Check lamp operating hours.
• Replace UV lamps according to manufacturer recommendations.
• Keep the enclosure dry and free from salt contamination.
• Perform insulation testing during scheduled maintenance.

SM MARINE SERVICE™ also provides inspection, testing, repair, and replacement support for Alfa Laval PureBallast electronic modules.

Why Ships Still Use Alfa Laval LPS M 3-6

Although ballast water treatment technology continues to evolve, thousands of vessels worldwide still operate Alfa Laval PureBallast systems equipped with the LPS M 3-6 Lamp Power Supply.

Ship owners continue using these systems because they offer:

• Proven operational reliability
• Stable UV lamp performance
• IMO-compliant ballast water treatment
• Long service life
• Global service availability
• Easy maintenance
• Modular replacement
• Excellent compatibility with existing PureBallast installations
• Reduced operating costs through repairable electronic modules

Many operators choose professional repair or reconditioned replacement units rather than purchasing entirely new control systems, making the LPS M 3-6 an important spare part for fleet maintenance.
