The Eltek range of modular power supplies has been specifically developed to meet the DC powering requirements for telecommunications and industrial applications.
High efficiency, low weight and - volume are achieved through the utilisation of switch mode technology.
SMPS 1000 SI offers the following features:
- “Hot” plug in facilitating installation and services
- Power factor corrected input providing reduced harmonics and minimal input power requirements
- Automatic Over Temperature derating for increased reliability
- Comprehensive alarm and control facilities for remote and local monitoring
- Compliant with International Standards
