The unit accepts a 24 V DC input and delivers a stable 24 V DC output at up to 15 A (approximately 360 W), powered by a capacitor energy store with a nominal capacity of 5 kW·s to bridge short power interruptions. It includes a USB interface for status monitoring and configuration, and the enclosure is IP20 protected for indoor control cabinets. The base unit measures about 125 mm high, 120 mm wide, and 125 mm deep and weighs roughly 1 kg. For longer hold‑up times, up to three PSU501S capacitor modules can be added to extend the buffer time without batteries. This makes the 6EP1933-2EC51 ideal for protecting 24 V DC loads such as PLCs, sensors, drives, and I\/O modules, enabling controlled shutdown or continuation of operation during brief outages or voltage dips in industrial automation environments. The UPS500S basic device with USB interface provides a compact, service‑free solution where rapid recovery and reliable uptime are critical, without the maintenance requirements of a battery‑based UPS.\u003c\/p\u003e\u003c\/div\u003e","brand":"Siemens","offers":[{"title":"New Surplus No Box","offer_id":46268484681962,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-018.png?v=1788727429","url":"https:\/\/gtghardware.com\/products\/siemens-6ep1933-2ec51-uninterruptible-power-supply","provider":"GTG Hardware","version":"1.0","type":"link"}
