Hur vi hanterar dina uppgifter
The UBEC is an external switching-mode DC-DC regulator chip. It draws the DC voltage from a 3-18S LiPo battery and drops the voltage to a level suitable for receivers and other electronic devices and keeps providing the stable current output of up to 25Amp. The UBEC has such a powerful output capability, so it is particularly applicable for the large helicopters or fixed-wing aircraft which use several servos.
Elegant Look & Powerful Core Component
Elegant metal case helps dissipate heat and reduce electromagnetic interference. High-efficient DC-DC voltage-regulating chip pairs with the specially designed circuit hardware for the conversion efficiency of over 90%. Continuous current of 25A (w/ peak current of up to 50A) meets various application requirements.
Various Functions & Different Applications
External switch allows users to easily switch on/off the UBEC. Wide voltage range allows the main power supply ranges from 3S to 18S LiPo to be connected to the UBEC. Output voltage adjustable between 5.0V, 6.0V, 7.4V and 8.4V meets different voltage requirements. Up to 8 channels of outputs (in parallel) can endure higher current. And the internal LED indicators can indicate the working status or abnormalities of the UBEC.
UBEC shoot-through protection, which prevents the voltage of the main power supply from directly flowing to the output end of the UBEC and causing any damage to the connected electronic device when the UBEC is accidentally damaged, plus the protections like over-current, (output end) short-circuit, overheat, low-voltage cutoff guarantee safety and reliability.
Backup Power Supply
Backup power supply switching-in function allows the electronic device connected to the UBEC to get power directly from the backup power supply to guarantee the continuation of the normal operation when the main power supply connected to the UBEC is damaged or the UBEC fails to function due to internal faults.
