The 125Vdc 40A power supply battery rectifiers are designed to offer a highly reliable power supply and charging capacity for DC electrical substation.
The model B220/125-40M2 charging all types of battery technology: NiCad (NicCd), Lead Acid, Lithium Ion (with integral battery management connected to its communications Bus) while supplying power to the DC load.
The 125Vdc 40A rectifier-charger charging voltage regulation is based on temperature, in float charge, parallel operation to increase redundancy or power with the inclusion of a decoupling diode.
The 125Vdc 40A rectifier-charger include a communication module with a TCP/IP interface (RJ45 port), and also communicate with a UTR or control center (SCADA) through the dnp3 communication protocol.
