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.
The new DC/DC convertor boasts a power density of 72.4W/in3 and power efficiency of 90% at an output of 3.3V.
Such high efficiency has eliminated the need for baseplate cooling under normal temperature conditions, allowing Lambda to produce a half-brick design that is both lighter and thinner.
Combining a typical weight of only 90g with a footprint of 58 x 61mm and a low profile of 10mm, the new PAH200H48 family of DC/DC power modules brings significant benefits to designs where board and inter board space is at a premium.
The open modules can be convection or forced air cooled, their inherent high efficiency helping to significantly reduce heat output.
Operating temperature range is -40 to +85C.
The convertors have built-in overvoltage, overcurrent and overtemperature protection.
Isolation withstand voltage is 1.5kV DC input-to-output.
For applications operating under harsh conditions of low airflow and high ambient temperature Lambda is also offering a version with a baseplate allowing operating temperatures as high as 100C.
The PAH200H48 provides designers with a choice of industry standard pin configurations, the C version having fewer output pins for simplicity and compatibility.
Other options include auto restart following overcurrent/overvoltage shutdown, and negative or positive remote on/off control.
PAH converters carry a full range of international approvals including UL1950, EN60950 and CSA950. Request a free brochure from Lambda ...
