Bel Power Solutions Announces Titanium Efficiency 3.6kW, 48 VDC Adjustable Output Power Supply


Santa, CA [Apr 19, 2023] Bel Fuse Inc, a leading global manufacturer of products that power, protect and connect electronic circuits, announces the expansion of their portfolio to include the TET3600-48-104RA, a 3.6kW Titanium efficient AC-DC front-end power supply that can convert up to 277 VAC into a main adjustable (42-58 VDC) output for powering high performance Datacenter, Network, Industrial and Broadcast applications.

The TET3600 delivers a power density of 56 W/in3 and achieves Titanium efficiency (>97% efficient at 50% load) in a compact package measuring 104 x 40 x 256 mm (4.09 x 1.57 x 10.08 in.). The AC-DC stage uses soft-switching resonant techniques to reduce component stresses, providing increased system reliability and very high efficiency, in conjunction with synchronous rectification. 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 up to 6 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. These power supplies meet international safety standards and display the CE-Mark for the European Low Voltage Directive (LVD) and have patents pending.

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