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 +48 VDC, these units comply with XP Power's 'green power' limits by having a no load power consumption of less that 0.5 W and average efficiency ranging from 83 - 90%, depending on the model. This helps designers ensure their end-products achieve internationally recognized environmental standards. A +12 VDC, or +5 VDC for 5 VDC output models, auxiliary fan output is provided should forced-air cooling be required.
Despite being designed to meet the price-point expectations of high volume applications, the VTF series incorporates all the control and signalling features normally associated with fully featured models. This includes overvoltage, overload and short-circuit protection, tight load and line regulation together with a remote sense capability. The 12V model is also available with optional blocking diode by adding a -D suffix to the part number.
Accommodating the full universal input range of 90 - 264 VAC, the series is able to deliver full power from - 10 degrees C to + 50 degrees C, and with derating up to + 70 degrees C.
The VFT series meets UL60950-1 / EN60950-1 safety specifications for IT, commercial and industrial equipment. In addition, the units comply with EN550022 level B standard for both conducted and radiated emissions without the need for additional filtering components.
The VFT150 series is available from Farnell or direct from XP Power.
