Artesyn RoHS-compliant 150 Watt AC-DC Power Supplies Are Ideal Front-ends for Distributed Power
Artesyn Technologies has introduced a new series of compact 150 Watt ac-dc power supplies that are ideal front-end conversion solutions for systems with distributed power and point-of-load architectures. The new TLP150 series power supplies provide a choice of 12 V, 24 V or 48 V outputs to simplify system integration, backed by extensive control and monitoring features to satisfy a wide variety of dc supply requirements. For distributed power applications, the 12 V model can be used to directly power boards fitted with multiple non-isolated point-of-load (POL) dc-dc converters, while the 24 V and 48 V models are suitable for feeding on-board isolated brick or intermediate bus converters. The 24 V model is also ideal for powering equipment with electromechanical loads such as relays, pumps and print-heads. In addition to the main output channel, each power supply also provides a 12 V output for powering fans, and an auxiliary ‘always-on’ 5 Vdc output for applications that require standby operation is available as an option.
All TLP150 series power supplies are Pb-free (RoHS 6/6) compliant. The 12 V and 24 V models are also available with full medical approvals, for applications such as patient monitoring systems and other portable equipment used in medical wards and surgical operating theatres. The medically approved versions have a very low safety ground leakage figure of 150 µA, compared to 1 mA for the industrial versions, and are equipped with fuses in both live and neutral inputs.
TLP150 series ac-dc power supplies employ an open-frame construction, combined with highly integrated layout and packaging techniques, to realize a small form factor, high functionality unit capable of delivering high levels of useable power. Measuring just 127 x 76.2 mm, with a profile of only 31.75 mm, the supplies have a power density of more than 1.75 Watts per cubic centimetre. The main output channel can deliver up to 100 Watts continuously under free air convection conditions, rising to 150 Watts with just 200 LFM forced air cooling. The power supplies accommodate a wide ambient operating temperature range of 0 °C to 70 °C, maintaining full rated output up to 50 °C.
All TLP150 series power supplies feature a universal input that accepts any voltage in the range 85 to 264 Vac at any frequency from 47 to 63 Hz, enabling them to be used in equipment destined for any part of the world. Active power factor correction minimises input harmonic current distortion and ensures compliance with the international EN61000-3-2 standard. The power supplies employ the latest high frequency switch-mode technology to maximise conversion efficiency, typically achieving 81% at full load with a 115 Vac input, and 84% with a 230 Vac input.
Primarily intended as low- to medium-power front-end units for distributed power systems, the small physical size and high functionality of TLP150 series ac-dc power supplies makes them especially suitable for use in information technology equipment (ITE), light industrial systems and medical equipment. Built-in control and monitoring features include ‘ac power good and ‘dc power good’ output signals and a remote on/off input, and the supplies are comprehensively protected against overcurrent, overvoltage and overtemperature conditions.
TLP150 series 12 V, 24 V and 48 V power supplies provide maximum main channel output currents of 12.5 A, 6.3 A and 3.2 A respectively. Active ‘democratic’ current sharing, enabling multiple units to be connected in parallel for higher current applications, is available on select models. These models also incorporate internal Or-ing diodes fitted to the main output, for fault-tolerant and N+1 redundancy applications.

All TLP150 series ac-dc power supplies comply with the rigorous EN55022-B and FCC part 15 Level B EMC standards for conducted noise and meet all applicable immunity standards, including EN61000-4-2, -3, -4, -5 and -6 levels 3. The power supplies carry UL/cUL60950-1 and EN60950-1 VDE safety approvals, and the medical versions are also approved to UL/cUL2601-1 and VDE EN60601-1. The standard industrial versions of the supplies have isolation ratings of 3000 Vac input/output and 1500 Vac input/chassis, while the medical versions have higher 4000 Vac input/output ratings.
Conor Quinn, Product Manager for Artesyn Technologies, points out that, "This is our second significant AC-DC standard product introduction in the last six months. It complements Artesyn’s broad portfolio of DC-DC converters and reaffirms our commitment to providing our customers with total solutions for all their power architecture needs."
