The generator produces direct current without the need for voltage converters, significantly increasing efficiency and eliminating issues common with AC generators in 24V systems such as solar setups, medical and telecom equipment, fire safety, and surveillance systems. It’s also ideal for maintaining or charging vehicle batteries during parking.\nThe generator features an AUTO mode, which uses an integrated controller that continuously monitors battery voltage and automatically starts charging when voltage drops, stopping when optimal parameters are reached. The second mode, MANUAL\/EXTERNAL, enables connection to an external device using a CONTROL TERMINAL for start\/stop control via \"dry contacts\".\nDirect battery connection simplifies installation, while external dry contact control significantly extends integration capabilities of the generator within existing power supply systems.\nThe soundproof casing reduces operating noise, making usage more comfortable. The control panel contains all necessary indicators, measuring instruments, and control devices. These include a voltage indicator showing generator voltage, an overload indicator signaling excessive load, and an oil level indicator showing the oil condition to help prevent engine damage due to low oil. Additionally, a voltmeter measures output voltage, and an ammeter displays current, enabling precise monitoring of the generator performance.\n","brand":"Könner \u0026 Söhnen","offers":[{"title":"Default Title","offer_id":54824169996613,"sku":"KS 24VS-DC","price":699.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0619\/0737\/0160\/files\/KS_24VS-DC_02.png?v=1748422400"},{"product_id":"ks-24vm-dc-constant-voltage-generator","title":"KS 24VM-DC Direct Current Generator","description":"The KS 24VM DC constant voltage generator by the German brand Könner \u0026amp; Söhnen® features a rated current of 60A and an operating voltage of 24–27.5V. This reliable and powerful device is designed as a backup charger for 24V batteries. Thanks to its high performance and specifications, this generator is an indispensable assistant in emergency or autonomous power supply for 24V systems.\nOne of the key advantages of this model is its constant voltage output. For user convenience, it features a mode switch enabling easy transition between manual and automatic operation, depending on needs and operating conditions. This significantly enhances comfort and usage scenarios, especially during frequent voltage fluctuations or when continuous power is required.\nIn AUTO mode, the integrated controller continuously monitors battery voltage and automatically starts charging when the voltage drops, stopping once the preset voltage is reached. Additionally, there is a MANUAL\/EXTERNAL mode designed for experienced users, enabling starting via the “CONTROL TERMINAL”. The generator connects directly to the battery, simplifying installation. External control via “dry contacts” significantly broadens integration capabilities with existing power supply systems. \nCombining advanced technical features, ease of use, and high reliability, this generator is an excellent choice for anyone seeking an efficient and durable autonomous power source for 24V systems such as solar power stations, medical and telecom equipment, security and video surveillance systems, vehicle 24V battery maintenance, and more.\nThe generator also includes an oil level sensor and indicator to automatically shut off the engine in case of low oil, preventing premature damage. An overload indicator helps avoid excessive loads, prolonging the lifespan of the device. Operational status indicators, along with integrated voltmeter and ammeter, ensure full control over the generator parameters, crucial for stable equipment operation.\nThe generator is made in a durable, noise-proof metal casing, which not only reduces the noise levels during operation but also provides additional protection of components from mechanical damage, dust, and moisture — making it suitable even for harsh environments.\nPowered by a reliable, eco-friendly 4-stroke gasoline engine meeting EURO 5 (STAGE 5) standards, this model ensures high performance, fuel efficiency, and long service life.\n","brand":"Könner \u0026 Söhnen","offers":[{"title":"Default Title","offer_id":54824831877445,"sku":"KS 24VM-DC","price":799.0,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0619\/0737\/0160\/files\/ks_24vm-dc_02.png?v=1749023684"},{"product_id":"ks-48vs-dc-direct-current-generator-version-50-55v","title":"KS 48VS-DC Direct Current Generator, version 50–55V","description":"The KS 48VS-DC constant voltage generator (50–55V version) by German brand Könner \u0026amp; Söhnen is a backup charging device designed for batteries with an operating voltage range that includes 50–55V.
