PowerTech MP3745 - External Temperature Compensation; WIFI Networking and USB Output

6
a. Reduceloadincaseofover‐temperature:thechargingcurrentisalways28‐30Awhen
theheatsinktemperature≥75°C.
b. Recoverwhenloadisreduced:resumenormalcharging(50A)whentheheatsink
temperatureis<70°C.
c. Stopchargingwhentheheatsinktemperatureis≥90°C;resume
chargingwhentheheat
sinktemperatureis<60°C.
5. Externaltemperaturecompensationfunction(onlyfor
AGM/STDbattery)
a.1.Thesystemwillautomaticallyadjustthefloatvoltageaccordingtotheambienttemperature.
Theexternaltemperatureprobeispreferred.Iftheexternaltemperatureprobeisnotconnected
(ortheexternaltemperatureis<40°C),use(temperature≥20°C‐5°C)bydefault.2.Thevoltage
mayvarywhentheinputenergyis
insufficienttostabilizetheenergyrequiredforthefloat
charging.
b.For12/24/36/48Vbatteries,whentheexternalprobetemperature≤0°C~40°C,thefloat
chargingvoltageis14.1/28.2V/42.3V/56.4V
For12/24/36/48Vbatteries,whentheexternalprobetemperatureis0°C~20°C,thefloatcharging
voltageis13.8/27.6V/41.4V/55.2V
For12/24/36/48Vbatteries,whentheexternal
probetemperature≥20°C,thefloatcharging
voltageis13.5/27V/40.5V/54V.
6. WIFInetworkingfunction
a. Theproductmayint egrateWIFImoduleornot.
b. IftheproductintegratesaWIFImodule,youcaninstallthemobileAPP,controltheload
switchthroughtheAPPandviewtheMPPTchargerdatainrealtime,suchasbattery
voltage,chargingcurrent,etc.
7. TheLCDbacklight
isturnedoffifthereisnobuttonoperationin1minute;anybutton
operationwillautomaticallyactivatetheLCDbacklight.
8. a.USBbatteryinputundervoltage/overvoltageprotection(10.5V/60V),batteryinput
undervoltage/overvoltagerecovery(11V/59V);
c. USBoutput2*5V/3A.
