XANTREX XFR40-70 is a 2.8kW programmable DC power supply that adopts zero voltage "soft switching" technology and is suitable for 19 inch rack installation. It focuses on clean and reliable power supply performance and is suitable for research, product development, production testing, OEM and other scenarios that require high power and wide adjustment range.
Product Core Features
Technical advantages: Soft switching technology eliminates switch transients, improves efficiency, reduces heat generation, and lowers switch transistor stress, resulting in higher reliability; Excellent thermal management, supports stacked installation, and does not require reserved ventilation space.
Operation and Control: The front-end panel can display both output voltage and current simultaneously, support automatic switching between constant voltage/constant current and mode indication, and has standby mode; Support remote detection (including 5V line loss compensation), compatible with LabVIEW and LabWindows drivers.
Protection function: Built in overvoltage protection (OVP) and over temperature protection.
Optional accessories: Isolation Analog Control Card (ISOL), RS-232 interface card, GPIB interface card, multi-channel GPIB.
