Frequently Asked Questions

What is the control voltage range? What is the applicable battery range?

The control voltage range is DC 6V-60V. But the battery voltage max is 48V. Because the voltage of a 48V battery can reach 60V after fully charged.

Why output is automatically turned on and off continuously after the power is on and the flashing light is?

This is because your charging current is too large or the battery capacity is too small which causes the battery voltage to exceed the Lower limit voltage ‘dn’ value immediately and then the output will be OFF. But the voltage drops quickly to the Lower limit voltage ‘dn’ after output OFF and then starts to charge. Cycle and cycle. At this point, you have to reduce the charging current. Usually, the charging current is 10-15% of the battery capacity. For example, if the battery capacity is 20AH, the charging current is 2-3A. Note that high current charging can cause the battery to heat up, aging, bulge, or even explode. 3>.

What control method?

This is the voltage control. For example, the Lower limit voltage ‘dn’ is set to 12.0V. The upper limit voltage ‘UP’ is set to 14.5V. It will close output when the voltage is charged to 14.5V. The output will be ON and begin to charge when the voltage is reduced to 12.0V. 4>.

Can it be automatically cycled?

Yes, it can. Voltage control mode only controls turn-off and turn-on. 5>.

Can it limit the current?

It can limit current, the charging current is completely dependent on your charger but can not be more than the set value oAP.

Can I charge a 24V battery by inputting 12V? Or charge a 12V battery by inputting 48V?

This is a simple voltage controller just for ON/OFF. It can not change the output voltage. So what kind of charger should you prepare for charging the battery?
