Product Description
Lauritz Knudsen MD1 iU Starter Plus DOL i ADSM – 10 HP is a high-performance, intelligent starter designed for reliable pump operations in 3-phase systems. With in-built i-ADSM protection, it automatically detects voltage imbalance, dry run, and reverse phase errors, preventing motor damage and increasing service life. The integrated digital metering panel and smart LED display offer ease of operation with on-field fault traceability.

Mechanism of Protection

• Detects and blocks pump operation during under/over voltage or phase reversal
• Automatically senses dry run condition and stops motor
• Provides protection from current imbalance and single phasing
• System auto-resets or alerts depending on fault nature and configuration

Recommended Usage

• Agriculture – Borewell pumps, drip irrigation setups
• Industries – Process water systems and pressure pumps
• Housing societies – Utility pump automation

Benefits

• Prevents pump burnout from voltage and current-related faults
• Improves safety and operational reliability
• Reduces motor maintenance and downtime
• Optimizes power usage and enhances pump efficiency

Usage Note
Ensure installation by certified electricians and follow guidelines in the enclosed user manual. Compatible with a wide range of submersible and surface pumps.
