Completely powered from batteries, this discharger is designed to operate with various battery systems and is extremely cost effective. It is completely powered from the Batteries under test, i.e. no mains supply is required. Therefore, tests are not terminated part way through, by a temporary mains power outage. The unit uses forced air-cooling. The Load is housed in a compact, rugged enclosure with and is lightweight for the power rating and is also completely portable. The Load may be left on site, unattended, for an extended period, if required. The Load Bank has constant current operation. The load current is continuously variable over the entire current range. The current can be controlled from front panel. It is possible to select the "End Voltage" per cell as per battery type. When enabled the load monitors the overall battery Voltage and when it drops to the "End Voltage" it will automatically disconnect the load and the current will drop to zero. Thus, the Battery Discharger now becomes an intelligent Load, it prevents deep discharge of the batteries and hence prevent any possible damage to them. When this load is used in conjunction with the BMS, (Battery Monitoring System) the 'End Voltage' can be programmed and this will automatically disconnect the load when the BMS senses that the 'End Voltage' has been reached. This feature will override the LVD in the load. Its panel has various rear panel connectors. The front panel has text Display for battery Voltage and discharge current. The Battery Discharger has been designed to be very reliable, easy to use and suitable for field use. It is thermally safe and has fan fail detectors for all fans together. The DC input is fused and over voltage protection is included. The DC power connection is on the rear side of panel.
