Bel Power Solutions announces titanium efficiency 3.6kw power supply

The TET3600 delivers a power density of 56W/in3 and achieves Titanium efficiency (>97% efficient at 50% load) in a compact package measuring 104 x 40 x 256mm (4.09 x 1.57 x 10.08in.). The power supply uses resonant soft-switching techniques, in conjunction with synchronous rectification, to reduce component stresses and provide industry leading efficiency and increased system reliability. It also has a DC input voltage range of 240-380VDC. 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 6 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, and have patents pending.
