Elektro-Automatik PSI10750-120 DC Power Supply

Overview

The Elektro-Automatik PSI10750-120 is a high-efficiency laboratory DC power supply from the PSI series, engineered for demanding test and development applications. It features a compact 4U form factor that delivers significantly more power in less rack space compared to earlier generation models. With a wide AC input range (342–528V three-phase), it is compatible with worldwide grid voltages including 380V, 400V, and 480V standards.

Key Features

• Output voltage range: 0–750V with autoranging output stage
• Maximum output current: 120A
• Total power: 30kW with efficiency up to 95.5%
• Flexible voltage/current trade-off: higher voltage at lower current, or higher current at lower voltage
• Active Power Factor Correction circuit for worldwide AC input (342–528V three-phase)
• Windows PC control software with direct SCPI and ModBus RTU command support
• Sequencing feature for semi-automatic table control and reproducible test profiles
• User and process profiles can be saved, edited, and archived
• Overvoltage (OVP), overcurrent (OCP), and overpower (OPP) protection thresholds

Applications

• Laboratory testing and device characterization
• Development and prototyping of power electronics
• Burn-in and reliability testing
• Multi-device control and automated test sequencing
