MEAN WELL produces a wide range of fanless power supplies with power ratings up to 2.5 kW for use in industrial applications.
The UHP series products are single-output power supplies which have a low profile ranging between 26 mm and 60 mm. They are intended for use in applications which require fanless operation with conduction or convection cooling. Eliminating the fan from the power supply relieves the user of concerns about premature fan failure. A fanless power supply is also suitable for applications which require silent operation.
Running from a universal 90 V to 264 V ac input, the power supplies are available in versions which provide an output voltage of 3.3 V, 4.2 V, 5.0 V, 12 V, 15 V, 24 V, 36 V, 48 V or 55 V dc and feature power ratings ranging from 200 W to 2.5 kW.
Optional PMBus® or CAN bus interfaces in the 1,500 W and 2,500 W UHP series power supplies ease integration into the sophisticated power installations in data centers and elsewhere, which use these communications interfaces for telemetry and control.
Offering high efficiency up to 96%, the UHP series operates over a temperature ranging between -30°C and 70°C with convection or conduction cooling and no fan. The power supplies are backed by a comprehensive set of protection functions. They also withstand vibration up to 5 g.
Some models in the UHP series of power supplies are also equipped with programmable voltage and current functions, enabling the trimming of the output voltage to between 50% and 120% of its nominal value, and the current to between 20% and 100% via an external DC control signal.
