Expanding 60W AC/DC power supply range now offers battery backup units

Stadium Stontronics has announced today that its SA60 AC/DC open frame power supply family has been extended to include two new 13.8VDC and 27.6VDC standard output units, and two new 13.8VDC and 27VDC small battery charger (SBC) units. The SA60 unit delivers up to 60W at 50C across the full input range of 90 – 264VAC. The units are typically rated at 85% efficiency and are CE marked and UL approved for ITE applications. They comply with a wide range of international standards such as EN61000-3-2 PFC Class A, EN55022 Level B (conducted) and Level A (radiated). The products are designed to have <0.5W no-load standby power to enable system designers to reduce energy consumption and meet global standards. The SA60 is packaged in an industry standard 50.84mm x 101.6mm x 29mm package. The SA60 range now includes 5V versions, rated at 40W, 12V, 13.8V, 24V, 27.6V, and 32V, in addition to 48V output versions that deliver 60W. Two new battery charger versions of the original SA60 platform, SBC60-27V6 and SBC60-13V8, have been added to the range to enable designers to easily implement a battery backup system within their host equipment design. The units, known as small battery chargers, have been extended in length (to 152.4mm) to accommodate additional battery charging circuitry and features such as a deep discharge relay, reverse battery protection, and a mains fail signal. Status LEDs for mains and battery modes are fitted to provide on-board indication, and an additional header is provided to facilitate the connection of further external LEDs for panel mounting if required. All units include over-voltage protection, over-current protection, non-latching thermal protection, and an optional temperature compensation feature via an external thermistor. The products were designed for users to easily, and cost effectively, add a battery-backed function to their system to reduce overall system costs and time to markets such as security, surveillance, CCTV and access control.stad
