These load works on 230 V AC ±10% 50Hz. Electronic load is very good tool to assess AH capacity of Battery. Further we can add features like Cutting off the discharge test as battery reaches to End Voltage and Timer(time totaliser) to count total discharge time on customers’ request.

Technical Specifications:

Typical Load Range: 0 - 20 A (settable by multi turn potentiometer)*
Load Current Regulation: ±0.05 % (for a change of battery voltage form no load voltage to end voltage level)
Line Regulation: ±0.05 % (for ±10% change in mains supply)
Power Requirement: 230 V AC ±10% 50Hz
Metering: 3 Digit Voltage Amp meter with selector switch indicates battery voltage and current or separate Volt and Ammeter.
Time Totaliser(Optional)
Press to set end voltage for battery discharging

Parameter	Range	Resolution	Accuracy
DC Volt	15 V	0.01 V	0.5% rdg ± 2 digits
DC Current	20 A	0.01 A	0.5% rdg ± 2 digits

* Note: Electronic Loads of higher ratings can also be designed to suit customer requirement.
