Description
DK-RM48 is a large-scale battery test system integrated with charge & discharge, auto-cycle test, it can set the voltage and current of charge and discharge by the user, and has automatic charging and discharging cycle function, the max. cycle number is up to 50 times. The instrument provides 7 work modes for easy operation. The equipment is widely used in battery production, battery recycling and other industries that require large-scale battery testing. 

DK exclusive charge and discharge module can be flexibly configured in the test system, the maximum discharge current can up to 50A, and the maximum charge current can up to 30A. 

Battery Charge Discharge Testing System



Applicable Batteries:
6V/8V/12V/16V/18V Lead-acid batteries, recommended capacity:<65 AH.


Features:
- Each channel is equipped with a dedicated processor to ensure a perfect level of capacity calculation, timing, voltage and current control.
- Instrument displays by LCD, each index is clear at a glance.
- The parameter setup and parameter switching are set and switched by a “START” switch and a “SET” knob. All parameters(voltage, current, mode) setting have the saving function.
- Intelligent speed fan can run continuously, delay the power-off of the fan, and blow-off the remaining heat.
- Polarity protection, anti-reverse connection, and so on.
- Each circuit is the independent module, no influence each other
- The instrument have simple mode and professional mode for choice to meet the different requirement of the user.
- Data protection startup: If the connection cables disconnected from the battery during the charging and discharging, after reconnecting the cables with the battery, press and hold the “Start” button to continue working.
- Power-off memory function.

- DK exclusive charge and discharge module can be flexibly configured in the test system, the maximum discharge current can up to 50A, and the maximum charge current can up to 30A.
