BSM-24-1500 and
BSM-48-1500 Rectifier 48 V-30 A/24 V-60A
Designed
for superior performance in telecom, data-com,
industrial and IT applications, the rectifiers
convert commercial 85-275 Volts Ac input power at 50 or 60 hertz into a highly regulated, filtered, low-noise and isolated 48 Volt Dc output. The unit achieves electrical efficiencies up to 91% with a power density of 5 W/in3. The
unit is designed to work in N +1 redundant configuration..
The 1500
W Rectifiers are hot swappable into BSMC’s
standard 19” or 23” sub-racks for easy upgrading
of your Rectifiers without interrupting the
load. Unit has “plug and play” capability (no
adjustments needed) so installation is quick and
simple. Up to five units will fit in a single
shelf, mountable in 23” rack. Four units in a 19" sub-rack Unit has alarm LED’s on the front panel to visualize working conditions.
It interfaces via RS 485 to BSMC’s power system controllers or RS 485 capable remote devices.
