Description
The power section is built on a thyristor bridge, and the microprocessor regulates the firing angle and holds the output voltage with an accuracy better than ±1 %. Charging modes are set for the battery type, vented or sealed lead-acid or nickel-cadmium Ni-Cd, which are often installed at power facilities. High regulation accuracy matters for sealed batteries, which are sensitive to overcharging and age quickly at excess voltage. The L 12P version has a 12-pulse rectification scheme, which noticeably reduces current harmonics in the supply network. Its cooling is natural, without fans, so less dust is drawn into the cabinet and there are no wearing parts.
How to choose
The current is selected so that it is enough for the load and for battery charging at the same time. The voltage is set by the battery, and the range of 24–220 V DC covers telecom, automation and substation control power. If the supply network is sensitive to harmonics and the current is 25 A or more, consider the L 12P. For small systems of several kilowatts the modular DC POWER-S / SD with 1000–2700 W modules in 2U is more convenient.

FAQ
What current do the DC POWER-L rectifiers give?
From 10 to 800 A, and in the 12-pulse version L 12P from 25 to 800 A at 24–220 V DC.
Which batteries does the DC POWER-L charger work with?
With vented and sealed lead-acid batteries, and also with nickel-cadmium Ni-Cd ones.
What is the voltage regulation accuracy of the DC POWER-L?
Better than ±1 %, which matters for charging sealed lead-acid batteries without overcharging.
How does the DC POWER-L 12P differ from the basic version?
The 12-pulse scheme gives low current harmonics in the network, and the cooling is natural, without fans.
