Can be charged with dual DC or DC+PD or PD+PD, and can be charged with dual DC output (requires parallel diodes or ideal diodes) (full blood version) * Note (the regular version only has 1 set of bidirectional DC/C).
- 4 independent C outputs, C1: 20V5A, C2: 20V5A, C3: 20V7A, C4: 20V7A (full blood version) * Note (regular version only has C1, C2, and C3).
- 1.83-inch color screen display, TI Texas Instruments Coulomb meter chip, TI Texas Instruments power path management chip, in addition to necessary current sampling resistance, the internal resistance of the power path on the board is as low as 1mR or less. ADI battery pack monitoring chip, independent single cell battery equalizer.
- 9 LED lighting, with infinite dimming, and a lighting power of 3.5W. Built in 5 UIs, can be selected by oneself, can set screen brightness, can set shutdown time and current, can charge low current charging devices C1 C2, and can customize private protocols.
Introduction to product functions and parameters
screen
Real time display of various data on a 1.83-inch color screen, with adjustable shutdown time/interface selection/LCD brightness/shutdown current(C1C2 current sampling is the sampling value setting for the customized version of the special protocol chip, and the default for non customized versions is 5mR).
A/B group buttons and A/B group output mode
A/B group K1 is used to set/C port output on/DC port output on, and other functions. Double click K1 to enter the corresponding group's setting interface (setting cannot be accessed during charging and discharging, and DC/C output cannot be enabled during setting). Double click again to select the setting content downwards. Click K1/K2 to add/subtract the content selected during double click Set, long press and hold KI/K2 to quickly add/subtract the selected content when double clicking. Short press K1 to turn on the output of port C, and then short press K1 again to turn off the output of port C. If there is no action or the load current is less than 30ma when turning on the output of port C, port C will automatically close after 10 seconds. Press and hold K1 for 3 seconds to turn on DC output. The DC output voltage is the set voltage. When the DC output current is greater than the set value, it enters current limiting protection. The load should be turned off in a timely manner or the current size should be adjusted. Press and hold again for 3 seconds to turn off DC output.
DC input port and adjustable DC output port
Two sets of bidirectional DC/C, DC adjustable output 4-24V, 12Amax, C output PD3.1 28V5A, DC charging 15-28V 12Amax, C charging PD3.1 28v5A, compatible with PD3.0. Can be charged with dual DC or DC+PD or PD+PD, and can be charged with dual DC outputs (parallel diodes or ideal diodes are required) (full blood version). Note (only 1 set of bidirectional DC/C is available for normal operation): 4 independent C outputs, C1 20V5A, C2 20V5A C3 20V7A, C4 20V7A (full blood version) Attention (regular version only has C1 C2 C3)
LED
The lighting power is 3.5W. Press the switch button for 0.5 seconds to turn on the power. Double click the switch button in the power on state to turn on the LED, and double click again to infinitely dimming. The LED brightness will be adjusted to its maximum, and then gradually decrease. You can choose a suitable brightness. Double click the button again to save the current brightness. Click to turn off the LED, and the next time the LED is turned on, it will be the brightness from the last time it was saved.
