MODULAR 50A RECTIFIER Simple Type: Rectifier
The NetSure A50B50 DC Power Retrofit provides a unique solution for maintaining and upgrading legacy Lorain DC power systems based on the A50B50 rectifier. Specially designed frames mount directly into existing rectifier slots without the need for electrical or mechanical adjustments. These frames accommodate the R48-3500E and R48-3200E eSure high efficiency rectifiers as well as the standard R48-3200 cool rectifier. Two distinct frames are available. Model A50IFRM accommodates a single rectifier and controller. Model A50EFRM houses a single rectifier. Each system does starts with one A50IFRM. The A50EFRM provides growth for up to thirty-six rectifiers in a single system. The NetSure A50B50 DC Power Retrofit can be used with or without the original A50B50 rectifiers in the same system. The frames contain the necessary connections and nice circuitry to manage the monitoring and alarming of all rectifiers. The system’s original meter-control-alarm panel can remain in place. Or, if desired, the NetSure controller can be used instead, providing significant enhancements over existing electronics including programmable alarming, customer I/O and local/remote access over Ethernet.
