Bel Power Solutions announces titanium efficiency 3.6kW, 48 VDC adjustable output power supply

Bel Fuse has expanded its portfolio to include the TET3600-48-104RA, a 3.6kW titanium efficient AC-DC front-end power supply that can convert up to 277VAC into a main adjustable (42-58 VDC) output for powering high performance datacentre, network, industrial and broadcast applications.

The TET3600 delivers a power density of 56 W/in3 and achieves titanium efficiency (greater than 97 per cent efficient at 50 per cent load) in a compact package measuring 10 x40x256mm (4.09×1.57×10.08in). The power supply uses resonant soft-switching techniques, in conjunction with synchronous rectification, to reduce component stresses and provide efficiency and increased system reliability. 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 suitable 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 +12V 30W 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. These power supplies meet international safety standards, display the CE-Mark for the European Low Voltage Directive (LVD), and have patents pending.

TET3600-48-104RA samples are available upon request. The TET3600 is also available from Arrow, Digikey, and Mouser.
