SWS-L Series

Compact and high-power AC/DC Power Supply

With output power levels of 600W and 1000W, these popular power supplies can operate across a wide ambient temperature range of -40 (start up) to 74°C. Temperature controlled cooling fans ensure low acoustical noise – important for laboratory and measurement equipment. In addition to meeting the IEC 60950-1 safety standard, the SWS1000L has medical certification to IEC 60601-1.

The Best Power Solution for Display Technologies

One of key purposes of SWS-L is to meet trends in LED display technologies. Users will appreciate the many features of SWS-L, especially its compact size. These supplies are the slimmest in their class. Acoustic noise is substantially reduced, which is important for indoor applications, while wide temperature ranges make it ideal for outdoor applications. With full conformance to international safety and EMC standards, designed-in reliability and extended field-life span, SWS-L reduces cost of ownership by saving the expenditures associated with maintenance, system down-time, and repair costs.

Low Profile

The SWS-L series is designed to have a lower profile than previous models. With the thin of 61mm, a 50% size reduction, these can be mounted in 2U or smaller locations. Compact size SWS-L is ideal for applications incl. the electronic display, vending machines and self-service kiosks.

Medically Approved for SWS1000L

Complying fully with EN/UL60601 safety standards including low earth leakage current and reinforced isolation, SWS1000L will also meet class B EMI and is the ideal choice for your medical power needs.

Low Fan Noise

The SWS-L is one of the quietest power supplies in their class. A temperature controlled fan adjusts its speed automatically, based on the temperatures surrounding the power supply. This substantially reduces annoying fan noise and wasted power consumption.

Wide operating temperature range

To operate reliably in outdoor environments a wide operating temperature range is necessary.SWS-L is designed to operate between -20℃ to 74 ℃. At its max. temperature, 74℃, 50% of the max. power rating is guaranteed.
