CE certified. Aluminum alloy casing in black and silver colours with heat sink design to reduce the possible damage from the heat. MOQ is 300 PCS. Lead-time 90-115 days. GFCI optional.
Wenchi's true sine wave power 300W inverter remains the same high standard, converting 12Vdc or 24Vdc battery power to 100Vac , 110Vac, 220Vac, 230Vac and 240Vac will be available. Peak(Surge) power is 600Watt. AC Frequency Output: 50Hz or 60Hz. Efficiency level is 85% to 90%. Thermal protection: 60±10℃, AC output 220V socket*1 or 110V sockets*2. Output fully isolation design. Best for retailers, distributors, importers, wholesalers, and manufacturers.
By connecting to the ACC cable that energizes with ACC ON of the engine key, you can turn the machine on/off with the engine key as the engine on/off. (* When connecting the ACC cabke with the engine, switch the inverter at the OFF position).
INT-300W Pure (true) Sine Wave Power Inverter can create precise power for applications. Do not produce electrical noise, so it will not damage your applications. Customized package is available when order reaches MOQ. Cooling by fan.
