The Lambda/TDK/EMI EMS13-90-2-D is a programmable switch-mode DC power supply delivering 13 V at 90 A output, engineered for laboratory testing and burn-in applications. This CV/CC (constant voltage/constant current) unit operates with automatic crossover and supports both analog and optional RSTL digital programming interfaces for local or remote control. Single or three-phase input accepts 190–250 VAC, providing stable, regulated output suitable for demanding industrial and commercial test environments.
## Technical Specifications
• **Output Configuration:** Constant voltage/constant current with automatic crossover
• **Output Voltage:** 13 V
• **Output Current:** 90 A
• **Power Output:** 2.6 kW maximum
• **Input Power:** Single or three-phase, 190–250 VAC
