The Lambda LPD425 is an EMI filter and power supply unit engineered to suppress electromagnetic interference across industrial and electronic applications. It delivers constant voltage or constant current operation with automatic crossover, supported by integrated metering and precision current limiting control. Built for regulatory compliance and field reliability, the unit combines compact architecture with effective noise attenuation to meet demanding EMI suppression requirements.
Technical Specifications
Input Power
• AC input: 105–132 VAC at 47–440 Hz
• Derating applies for 47–53 Hz operation (10% current reduction); 57–63 Hz ratings apply nominally
• Maximum DC voltage capability: 500 V between +DC or −DC terminal and chassis ground; 300 V maximum between either output terminal and ground
Operating Modes
• Constant Voltage or Constant Current with automatic crossover
• Single ten-turn potentiometer for current limiter adjustment
– Key Features
• Integrated voltmeter and ammeter on all LPD series models
• Selectable grounding: negative, positive, or floating output terminal configurations
• Excellent EMI attenuation characteristics for noise suppression
• Compact footprint enabling space-constrained installations
• RoHS compliant construction
• Safety agency approvals
– Typical Applications
The LPD425 serves applications demanding precision voltage or current regulation with integrated EMI filtering—industrial control systems, test benches, laboratory power distribution, and equipment requiring regulatory electromagnetic compatibility certification.
– Compatibility & Integration
The unit supports negative or positive grounding schemes, providing flexible integration into systems with varied ground architectures. Integrated metering eliminates the need for external monitoring instrumentation in bench and production environments.
