Open-frame 150W ac-dc power supplies

XP Power's VFT series of low cost 150W single output ac-dc power supplies are aimed at high-volume, cost-sensitive applications. Packaged within the industry standard 3in x 5in format and measuring just 1.4in high (76.2 x 127.0 x 33.2mm), the VFT150 series can provide a full 150W output when force-cooled with only 15ft3/min airflow. Using convection cooling alone, the units can provide up to 100W output.

The VFT150 operates from a universal input of 90-264 VAC and has active power factor correction. Providing the nominal outputs of +5, +12, +15, + 24 or +48Vdc, these units comply with XP Power's 'green power' limits by having a no-load power consumption of less that 0.5W and average efficiency ranging from 83 - 90%, depending on the model.

The VTF series incorporates all the control and signalling features normally associated with fully featured models, including over-voltage, overload and short-circuit protection, tight load and line regulation, together with a remote sense capability.
