Tápadapter DC 4,5-60V-tól 1,25-30V-ig 3A 90W Buck átalakító/Állítható feszültségszabályozó/Meghajtó /5V 12V 24V tápegység modul
Power Adapter DC 4.5~60V to 1.25~30V 3A 90W Buck Converter/Adjustable Voltage Regulator/Driver /5V 12V 24V Power Supply Module
Module parameters
Module nature: non isolated buck module
Rectification mode: asynchronous rectification
Input voltage: 4.5-60v (it can work at 60V and 61V measured)
Output voltage: (1) continuously adjustable (1.25-30)
(2) Fixed output (any choice between 1.25-30), (temporarily only for batch orders).
The default shipment is adjustable output.
Output current: 3A 30V 3A full load 90W
Conversion efficiency: 92% (the smaller the pressure difference is, the higher the efficiency is). See the following test diagram for details
Switching frequency: 50KHz
Differential pressure: 2V
Working temperature: industrial grade (- 40 ℃ to 85 ℃) (output power is within 20W)
Full load temperature rise: 40 ℃
Load adjustment rate: ± 0.5%
Voltage regulation rate: ± 0.5%
Output ripple:
Input 48V output 5V 3A ripple less than 10mV
20m bandwidth
Dynamic response speed: 5% 200us
Short circuit protection: current limiting, self recovery (output voltage lower than 20V)
Output overvoltage protection: the adjustable output does not have overvoltage protection function, and the fixed output can choose the output with overvoltage protection function.
Input reverse connection protection: Yes.
Installation method: screw fixation (diameter 3mm), 2 fixing holes, and the distance between the 2 fixing holes is 82mm
Wiring mode: the terminal can be plugged in and out and crimped without welding
Shell: all aluminum shell, potting process, can work under harsh conditions
Scope of application
1）. Step down: it is used for the step-down of 12V 24V 36V 48V storage battery. The input voltage can withstand 60V, and the output is stable, such as 3.3V 5V 9V 12V 24V, etc.
2）. Poe remote power supply. Switches, routers and 48V long-distance network cables transmit power.
