The TDK-Lambda EMS13 series comprises high-frequency switching power supplies engineered for laboratory test and burn-in applications. These units deliver precisely regulated, adjustable DC output in either constant voltage or constant current mode with automatic crossover operation. Designed for both single and three-phase input configurations, the EMS13 series combines high efficiency with compact, lightweight packaging while maintaining exceptional load regulation and transient performance.
## Technical Specifications
**Output Regulation**
• Voltage mode: <0.1% deviation across 100% load change (full load to no load)
• Current mode: <0.1% deviation across 100% load change (full load to short circuit)
• Soft-start standard on all models—inrush current during turn-on, turn-off, power interruption, or reapplication remains below full-load current levels
**Operating Environment**
• Continuous duty: 0°C to 70°C with 1% per degree Celsius derating above 50°C
• Storage temperature: -55°C to +85°C
• Internal fan cooling
**Ripple Performance**
Ripple specifications are model-dependent. Three-phase input configurations achieve approximately 30% of peak-to-peak carrier ripple. Reduced ripple option (40 mV P-P carrier) available on models rated to 40 VDC output via EMS II designation.
## Key Features
• Fully programmable via analog interface or optional RSTL digital interface
• Local programming: voltage and current channels independently adjustable
• Remote programming: voltage channel via external resistance or 0-10V external voltage; current channel programmable remotely
• High packaging density with minimal weight
• Transient response and stability optimized per local programming configuration
## Typical Applications
• Laboratory power supplies for component testing
• Burn-in test environments requiring stable, adjustable output
• Multi-phase industrial input environments
• Systems demanding precise current or voltage sourcing with minimal regulation error
## Compatibility & Integration
The EMS13 series integrates with both analog and RSTL digital control systems, enabling flexible configuration in automated test and measurement setups. Single and three-phase input support accommodates diverse facility infrastructures.
