LB-48-300 (48Volt, 300Amp)

The LB-48-300 is specially designed for a discharge test, capacity test, battery maintenance, engineering examination and other tests for 48VDC power units by applying a load up to 300Amps.

Standard available loads are 0-100Amps, 0-200Amps, 0-300Amps. Resolution 1Amp.

The LB-48-300 is your smart, safe and environmentally-friendly load bank.

*Wireless communication is optional for real-time monitoring during discharge

Why a battery discharger?

Batteries in power utilities, telecom or any other backup power system must provide the equipment they serve with timely and sufficient power in case of a power failure. However, due to various reasons, the battery capacities could drop dramatically before they are needed for power backup. Costs could be tremendous once the standby batteries fail to work properly at the critical moment. Therefore, it becomes essential to check the batteries capacity on a regular basis. The only reliable way to measure the battery capacity is to carry out a discharge test. This “must-do” job also extends the life span of standby batteries (recommended by IEEE 1186-1996 for battery maintenance). Eagle Eye LB-24-300 series battery discharge monitors feature a unique design and excellent performance characteristics that will facilitate your battery maintenance work. Discharging values of each cell can be viewed on the LCD display and computer simultaneously by using the analyzing software.
