AC-DC converters get thumbs-up for global use

The converters have a universal input range of 85 – 264VAC or 120 – 370VDC and cover standard outputs of 12V, 24V & 48V, with the opportunity to adjust the outputs by up to 15%.

In addition to a superior EMC performance, with a high level of stability and immunity to noise, all models are certified to EN61000-3-2 Class D for harmonics.

They are also equipped with power-fail monitoring outputs and safety features include 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 dimensions of 110.00 x 32.00 x 124.00mm.

It offers efficiency up to 94% and 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 AC-DC converter also has a 150% peak load output for three seconds.

It is an energy-efficient and, like the LIF120, has an additional 12V option as well as 24V and 48V outputs.

The 480W LIF480 R2 is reliable with efficiency up to 94% and with an active PFC above 0.95.

In addition to the same safety features as the LIF120 and LIF240, it also has high I/O isolation test voltage up to 3000VAC.

Dimensions for the LIF240 R2 Series are 124.00 x 41.00 x 110.00mm. The LIF480 R2 measures 131.5 x 48.0 x 125.0mm.

Operating temperature range for the LIF120 and LIF240 is LIF480 is -40°C to +70°C and -30°C to +70°C for the LIF240 and LIF480.

All models are covered with a three-year warranty and available from Relec Electronics on short lead times.
