ADDITIONAL INFO:
Load short
circuit
protection
When a short circuit occurs on the load side (which is 4 times
higher than the rated load current), the controller automatically
cuts o the output. The output still attempts to resume five times
automatically (delay 5 seconds, 10 seconds, 15 seconds, 20
seconds, 25 seconds). Suppose you want the controller to restart
the auto recovery process. In that case , you need to press the
Load button, or restart the controller, or experience a night to
day change (night time 3 hours).
Overload
protection
If the load current exceeds 1.05 times the controller's rating, the
controller will cut o the output after a delay. After the overload
occurs, the output attempts to resume automatically five times
(delay of 5 seconds, 10 seconds, 15 seconds, 20 seconds ,25
seconds). Suppose you want the controller to restart the auto
recovery process. In that case, you need to press the Load
button, or restart the controller, or experience a night to day
change (night time 3 hours).
Controller
Overheating*
An internal temperature sensor can detect the internal
temperature of the controller. The controller stops working when
the internal temperature exceeds 85°C and resumes work when
the internal temperature is below 75°C.
TVS high voltage
transients
protection
The controller's internal circuitry is designed with Transient
Voltage Suppressors (TVS), which can only protect against high-
voltage surge pulses with less energy. Suppose the controller is
to be used in an area with frequent lightning strikes. In that case,
it is recommended to install an external surge arrester.
* When the control's internal temperature is 81°C, the reducing power
charging mode is turned on, reducing the charging power of 5%, 10%, 20%,
40% every increase of 1°C. If the internal temperature is greater than 85°C,
the controller stops charging. When the internal temperature is not more
than 75°C, the controller will resume charge as per the rated power.
