3.6kW front end for hot swap 48V systems
Bel Fuse has launched a 3.6 kW Titanium efficient AC-DC front-end power supply that can convert up to 277 VAC into a main adjustable (42-58VDC) output for powering high performance datacentre, network, industrial and broadcast applications.
The TET3600-48-104RA has a power density of 56 W/in3 and Titanium efficiency of 97% efficient at 50% load in a package measuring 104 x 40 x 256 mm (4.09 x 1.57 x 10.08 in). The power supply uses resonant soft-switching techniques in conjunction with synchronous rectification, to reduce component stresses.
It also has a DC input voltage range of 240-380 VDC. An active OR-ing device on the output ensures no reverse load current and renders the supply ideally suited for operation in redundant power systems. These power supplies are hot swappable and can be connected with up to six units in parallel with active digital current sharing.
An always-on +12 V 30 W standby output is also provided.
The TET3600 features system communications via I2C/Power Management Bus protocol or CAN allowing full monitoring and limited control of the supply, voltages, current, power and temperature. Multiple protections such as overvoltage, overcurrent and overtemperature are standard and fault captured as needed via an onboard ‘blackbox’.
TET3600-48-104RA samples are available upon request and available from Arrow, Digikey, and Mouser.
