General-purpose power supplies boost efficiency
The LS50, LS75 and LS100 have 88 to 264V AC inputs, while the LS150 is switch-selectable for 115 or 230V AC, minimising the cost.
Power supplies cater for short-term peaks
Units provide a very cost and space efficient solution compared with oversizing conventional power supplies just to handle the peak current.
It is the perfect choice for a wide range of telecomms, IT and industrial applications allowing designers to take full advantage of forced-air cooling to achieve higher output current over a wider temperature range.
The UX40 is highly efficient with an 89% rating at ambient temperature.
Switching frequency is 265kHz.
The UX40 has an operating input voltage of 48V nominal over a 36-75V DC range and has a single 3.3V output.
With convection cooling the 3.3V UX40 provides a maximum output current of 7.5A up to 50C.
Applying forced-air cooling at the rate of 1.5m/s to the same device allows the designer to achieve a maximum output current of 12.0A right up to 70C.
Standard features include output current limiting, output overvoltage protection, input undervoltage lockout and thermal protection.
Options include output voltage adjustment via an external resistor.
Two remote on/off options are available Because the new UX40 is manufactured at its world-class production facility in Ilfracombe, Lambda can offer low minimum order quantities, ideal for prototyping and preproduction designs.
Samples can be delivered within one week of order and volume quantities can be supplied in less than four weeks.
All versions of Lambda's UX series of DC/DC convertors are CE marked and UL, CSA and VDE compliant. Request a free brochure from Lambda ...
