600W power supply is low-cost, low-profile and low-noise

Low-cost and low-profile, yet boasting advanced features such as active power factor correction and high transient protection, Lambda UK's latest 600W single-output power supply meets a wide range of indoor and outdoor applications, including display and signage.

The SWS600L offers a choice of output voltages from 3.3-48V DC and has a peak output of 744W on the 24V model. Important standard features include a 12V 0.1A auxiliary output, 'fan fail' alarm and 'DC output good' signal.

Operating within a temperature range of between –20 and +74degC and with low-temperature start-up capability (100 per cent load start-up at –40degC), it is a reliable choice for systems that experience extremes of temperature, such as road traffic signs. Meanwhile, the inclusion of a temperature-controlled fan that minimises acoustic noise means that the SWS600L is equally suited to indoor applications. An SWS600L unit operating at 25degC has a fan noise of just 43.5dB and is therefore suitable for powering laboratory equipment or a vending machine, for example.

Zero stacking capability

The SWS600L is small in size and is easy to fit into 2U enclosures, with a low profile at just 61mm high and length of only 190mm. When integrated into an end system, the compact form factor ensures maximum space utilisation. Significantly though, the unit features true zero stacking capability, allowing for up to five units to be installed in racks, one on top of the other, without requiring gaps to be left between them. Air inlets on only the front and rear facilitate this arrangement, permitting the unit to be enclosed at the sides. Meanwhile, an active current balance feature enables multiple units to share the load evenly when they are used together in high load and redundant applications.

The SWS600L accepts a continuous input from 85-265V AC. It boasts a wide +/-20 per cent output voltage adjustment range by trimmer to accommodate non-standard system voltages, while external programming enables the unit to be remotely adjusted from 20 to 120 per cent of nominal.

With an input transient protection that meets IEC 61000-4, the SWS600L has been shock tested to satisfy MIL-STD-810F 514.5 Procedure I, VI and vibration tested to MIL-STD-810F 514.5 Category 4, 10. The SWS600L is CE marked and meets Class B EMI standards and is safety-approved to UL, CSA, EN 60950-1, IEC 61010-1, and EN 50178.
