BTS Powersafe — stabiliser with isolation transformer for base stations
Country: Italy · Model: BTS Powersafe
BTS Powersafe is designed for cellular base stations and other telecom sites where rectifiers, inverters and air conditioners depend on the grid quality. The stabiliser keeps the equipment running during deep voltage fluctuations, so the backup diesel generator does not start at every sag.
- Purpose
- powering rectifiers, inverters and air conditioners at telecom sites
- Galvanic isolation
- isolation transformer
- Surge protection
- three-pole SPD

Description
At a remote site every diesel start means fuel use, engine life and often a crew visit, so a stabiliser at the supply noticeably reduces the number of such events. Inside is an isolation transformer that galvanically separates the load from the grid and attenuates noise coming along the line. A three-pole SPD built into the same cabinet protects against lightning and switching surges. Behind the stabiliser work rectifiers that charge the station's batteries, inverters for AC consumers and air conditioners of the equipment room. Air conditioner compressors tolerate low voltage poorly, so stable power preserves their service life.
How to choose
The power and input voltage range of BTS Powersafe are agreed for the particular station, so for the enquiry gather the total load of rectifiers, inverters and air conditioners and data on grid sags at the site. When a static circuit with no moving parts, ±1 % accuracy and a 30 ms response is needed, look at the PWM version on IGBTs. For an industrial supply of 10–300 kVA without an isolation transformer, the electromechanical BST-T is suitable, and above 400 kVA the BST-TH series.

FAQ
Why is a stabiliser needed at a base station if there is a diesel generator?
The stabiliser keeps the equipment on the grid during deep voltage fluctuations, and the diesel does not start at every sag. This saves fuel and generator engine life.
Which telecom site consumers are connected to BTS Powersafe?
The station's rectifiers, inverters and air conditioners, that is, all equipment powered from the AC grid.
Does BTS Powersafe have galvanic isolation from the grid?
Yes, an isolation transformer is installed inside. It separates the load from the grid and attenuates noise coming along the line.
How is the BTS Powersafe stabiliser protected against lightning surges?
A three-pole surge protective device (SPD) is built into the cabinet and diverts surges before they reach the station equipment.
How does BTS Powersafe differ from the PWM version?
The PWM version is built on IGBTs without a variator and drive, holds ±1 % accuracy and responds in 30 ms. The base model puts the emphasis on the isolation transformer and noise protection.
