Voltage: 12 VA: 500 Peak Power: 900W Max Efficiency: 90% Plug Type: UK IP Rating: IP21 Dimensions (Including Terminals): 86 x 172 x 275mm Weight: 3.9Kg assure: 5 Years Inverters allow you to power domestic equipment ? requiring 230V/120V AC ? using ?leisure? or ?automotive? batteries rated at 12V 24V or 48V DC. Features VE.Direct communication port The VE.Direct port can be connected to: A computer (VE.Direct to USB interface cable needed) Apple and Android smartphones tablets MacBook?s and other devices (VE.Direct Bluetooth Smart dongle needed) Fully configurable: Low battery voltage alarm trip and reset levels Low battery voltage cut-off and restart levels Dynamic cut-off: load dependent cut-off level Output voltage 210 ? 245V Frequency 50 Hz or 60 Hz ECO mode on/off and ECO mode sense level Monitoring: In- and output voltage % load and alarms Proven reliability:The full bridge plus toroidal transformer topology has proven its reliability over many years. The inverters are short circuit proof and protected against overheating whether due to overload or high ambient temperature. High start-up power:Needed to start loads such as power converters for LED lamps halogen lamps or electric tools. ECO mode:When in ECO mode the inverter will switch to standby when the load decreases below a preset value (min load: 15W). Once in standby the inverter will switch on for a short period (adjustable default: every 2 5 seconds). If the load exceeds a preset level the inverter will remain on. Remote on/off:A remote on/off switch can be connected to a two pole connector or between battery plus and the left hand contact of the two pole connector. DC connection with screw terminals:No special tools needed for installation. html-body [data-pb-style="639072568FE67"]{justify-content: flex-start; display: flex; flex-direction: column; background-position: left top; background-size: cover; background-repeat: no-repeat; background-attachment: scroll; border-style: none; border-width: 1px; border-radius: 0px; margin: 0px 0px 10px; padding: 10px;} html-body [data-pb-style="639072568FE71"]{border-style: none; border-width: 1px; border-radius: 0px; margin: 0px; padding: 0px;}
