The LIF120 R2, LIF240 R2 and LIF480 R2 are all IEC/EN/UL62368, UL61010, UL508-approved, which means they are suitable for use worldwide. They have a universal input range of 85 – 264V AC or 120 – 370V dc and cover standard outputs of 12V, 24V and 48V. Outputs can be adjusted by up to 15%.
The ac/dc converters have a high level of stability and immunity to noise, confirms Relec, with all models certified to EN61000-3-2 Class D for harmonics. They are also equipped with power-fail monitoring outputs, together with output short circuit, over-current, over-voltage and over-temperature protection.
The LIF Series’ slim width and compact dimensions are ideal for standard DIN-rail mounting. The cost-efficient ac-dc converters are particularly suitable for saving space in harsh operating environments, for example in industrial control equipment and machinery.
The 120W LIF120 R2 has a peak output of 180W for three seconds and measures 110.00 x 32.00 x 124.00mm. Efficiency is up to 94% and it also has 150% peak load output for three seconds. An ATEX-approved, explosion-proof version is also available as an option.
The LIF240 R2, 240W model also has a 150% peak load output for three seconds. Like the LIF120, it has an additional 12V option as well as 24V and 48V outputs. Dimensions are 124.00 x 41.00 x 110.00mm.
The 480W LIF480 R2 has efficiency up to 94% and an active PFC above 0.95. It has the same safety features as the LIF120 and LIF240, and a high I/O isolation test voltage up to 3000V AC. It measures 131.5 x 48.0 x 125.0mm.
Operating temperature ranges from for the LIF120 and LIF240 is -40°C to +70°C and -30°C to +70°C for the LIF480.
All models are covered with a three-year warranty and available from Relec Electronics on short lead times.
