DC Generator KS 48V-DC (Refurbished Good)

Q: What type of batteries are used for charging?

The KS 48V-DC direct current generator is designed for charging LiFePO₄ and Li-ion batteries, the operating voltage range of which overlaps with 48–53 V. The KS 48V-DC Version 2 generator is designed for charging LiFePO₄, Li-ion, AGM, and Lead Acid batteries, the operating voltage range overlapping 48-55 V.

Q: Can the generator be used with LiFePO₄ batteries?

The KS 48V-DC, direct current generator, can be used to charge LiFePO₄ batteries with a nominal voltage of 48 V. The KS 48V-DC Version 2 generator is recommended for LiFePO₄ batteries with a nominal voltage of 51.2 V.

Features

The KS 48V-DC direct-current generator from the German brand “Könner & Söhnen” is designed as a backup battery charger for charging 48-54 V batteries. The generator is ideal for charging batteries used to power private households, off-grid, solar, wind, telecommunication systems, boats, campsites, etc.

DC generator KS 48V-DC from Könner & Söhnen® provides:

Maximum efficiency

This method of charging is more efficient since there are no intermediate current conversions and associated with this energy losses.

Compact sizes and high power

High charging power in a small size generator - the generator is designed by analogy with the inverter type of generators. It takes up 3-5 times less space than a set consisting of regular 230V generator with alternating current and a powerful charger that converts 230V alternating voltage into a constant voltage necessary to charge the battery. Equipped with a transport kit for easy movement.

Safe use

The absence of life-threatening high voltage protects the user from electric shock while using the generator.

Economic choice

The efficiency of the generator is higher due to the absence of unnecessary conversions, as well as due to the adjustable number of revolutions depending on the load, which reduces fuel costs compared to classical methods using 230V AC generators with subsequent conversion.

Simple installation

The generator connects directly to the battery, which greatly simplifies installation. The possibility of external control of "dry contacts" significantly expands the possibilities of integrating the generator into existing power supply systems.

The DC battery charging voltage range should match the battery rating. With the integrated controller, the generator constantly monitors the battery voltage in AUTO mode and automatically starts charging the battery when its voltage drops to 48 V or lower. The generator has a response time of only 5 seconds. When the battery voltage reaches 53.5-54 V or a charging current of 20 A, the generator shuts down within 30 seconds. In addition to the AUTO mode, the generator has an EXTERNAL mode (or the so-called “dry contact”) for seasoned users, enabling the generator start to be controlled via an additional relay.

The KS 48V-DC direct-current generator is equipped with transport wheels and a carrying handle for easy handling, making it a much more versatile model. The battery can be charged in places where there is no mains power supply.

The robust Könner & Söhnen engine meets all European quality standards, including the latest EURO V emission standard. The high-end alternator with copper winding and the branded engine guarantee trouble-free and long-term operation.
