How does a telecom rectifier work?

Telecom rectifiers convert AC to DC power at the base of macro towers so that DC power can be sent to the DC devices that need it at the top. Traditional telecommunications equipment generally requires 48V DC input power.

Why do telecom sites need a rectifier?

Each telecom site requires a rectifier to convert the incoming AC voltage to DC voltage needed to power equipment. Rectifiers are also responsible for charging backup battery systems in the event of power cuts. Sites must have multiple battery strings providing -48V DC to power devices when utility power is lost.

What does a rectifier do?

Rectifiers are also responsible for charging backup battery systems in the event of power cuts. Sites must have multiple battery strings providing -48V DC to power devices when utility power is lost. The number of battery strings depends on the site's load and importance.

What is a boost stage in a telecom rectifier?

The boost stage often exists in the anatomy of a telecom rectifier as a byproduct of active power factor correction (PFC). Power factor needs to be corrected because there are typically reactive power losses along cables that result in voltage drop.

Does Benning offer fit-form-function modernisation of existing Telecom DC power supplies?

BENNING now offers the possibility of FIT-FORM-FUNCTION modernisation of existing (BENNING) Telecom DC power supplies by replacing older rectifier plug-in units with modern TEBECHOP SE rectifier units. The advantages at a glance: Enhancements are possible without downtime through simple "plug & play".

How much power does a telecom rectifier use?

The total power of a rectifier is DC output voltage multiplied by DC output current. Power ratings for telecom rectifiers vary from company to company, but these are the typical options: Low power ratings typically reach 400W, 800W, 1200W, 2000W, 2500W, 2900W or 3000W.
