Power supply installation PSI



Power supply installation (PSI 220/48) is designed for uninterruptible power supply with DC of 48 V and AC of 220 V. It is an uninterruptable power supply of ENTEL trademark, model SPE.                                                                                  

Distinctive features

Each PSI is designed and manufactured strictly focusing on the customer's requirements, it allows to optimize the PSI on such parameters as:

– Functionality;

– Constructive proposals;

– Ergonomics;

– Upgradeable during operation;

– The cost.

These features make it easy to integrate the PSI in its customer power saving system, and its operation significantly improves the reliability of the power system, power quality, and reduces the serviceability of the power supply system. 


- Online monitoring and diagnostics of power quality, status of protective devices;

- Generation of alarm signals during short-circuit currents, power surge, failure of power supply system components;

- Selective load shedding;

- AC and/or DC power supply protection, including dual redundancy.


Complies with TR CU 004/2011 and TR CU 020/201

Application area   

Consumers of first, special category, communications facilities, socially important objects.
