In some stand alone applications where there are installed 2 or 3 different battery banks with different voltages, there are often required a possibility to recharge individual betwenn the different banks. This is now possibel by using our 2-step DC chargers. The smallest chargers are from 360W to 500W.

• input voltage: from 70VDC to 300VDC
• output charge voltage: nom. 12VDC, 24VDC or 48VDC
• charging current: 20A max.  

This 1kW DC charger can be used as a charge controller for solar applications or wind power applications. A special version can be set up so it can be used as a DC-DC charger between 2 different battery banks. 

• input voltage: 150VDC max.
• output voltage: nom. 12DCV, 24VDC or 48VDC
• charging current: 40A max.
• MPP-Tracking System

These DC chargers are available from 250W to >2kW. The 2kW / 2,5kW have same features as the 1kW, and used in same applications. But here is also an LCD display option available. 

• input voltage: 150VDC max.
• output voltage: nom. 12VDC, 24VDC and 48VDC
• charging current: 100A max. for 2kW / 2,5kW ver. 
• MPP-Tracking System

Our DC-DC converters are very compact and have low weight. They have low self power consumption and the efficiency is round 90%. All got short circuit and overcurrent protection.

• input voltage: 24VDC, 48VDC
• output voltage: 12VDC, 24VDC
• output current: 22A max.

A new designed DC-DC converter with a wide operating voltage input. High efficiency converter with an adjustable voltage output. Protection against short circuit, overcurrent and overtemperature.

• input voltage: 96VDC - 300VDC
• output voltage: 12VDC - 14VDC
• output current: 22A max.
