Lambda / TDK / EMI EMS10

The Lambda / TDK EMI EMS10 is a switch-mode AC-to-DC power supply engineered for precision laboratory and industrial applications. This series delivers constant voltage/constant current operation with automatic crossover, combining high efficiency with compact, lightweight design. Built-in soft-start protection, comprehensive output safeguards, and full programmability make it suitable for test, burn-in, semiconductor processing, medical research, and scientific environments.

## Technical Specifications

**Regulation & Stability**
• 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)
• Long-term stability: ±0.05% maximum over 8-hour period at constant line, load, and temperature
• Output voltage temperature coefficient: 0.02% per 1°C of rated voltage
• Output current temperature coefficient: 0.03% per 1°C of rated current

**Transient Response**
• Load step 30% below 20V: 650 µs
• Units above 20V: Vmax/20

**Protection & Cooling**
• Soft-start input current limiting (standard on all models)
• Overvoltage, overcurrent, and thermal protection
• Forced air cooling on designated models

## Key Features

• Fully programmable voltage and current channels
• Analog programming interface
• Optional RSTL digital interface for system integration
• Remote programming via external resistance or voltage
• Lightweight design—some models weigh as little as 3.5 lbs

## Typical Applications

• Semiconductor device testing and processing
• Laboratory burn-in and characterization
• Medical device development and validation
• Scientific research and instrumentation
• Industrial and commercial power sourcing

## Compatibility & Integration

The EMS10 series supports analog control natively and optional RSTL digital connectivity for automated test systems. Remote voltage and current programming enables flexible integration into multi-channel test benches. As a component supply, final apparatus compliance with EMC Directive requirements remains the responsibility of the system integrator.
