22A Battery Eliminator Circuit (UBEC) for Multi- and Single-Rotor (UAS) Series
  • $65.00



The UBEC series is compatible with 2S LiPo - 8S LiHV power systems - allowing for clean, voltage-regulated power for critical flight electronics and peripheral equipment (including 12V aerial photography and high-end UAS equipment). The KDEXF-UBEC22 is designed to eliminate the need for an external battery pack, and allows for simple adjustment of the regulated output voltage for direct compatibility to your electronics and power applications. Three (3) power-output leads are provided as standard, preventing the need for any wire-harnesses or additional soldering when using high-powered electronics up to 10A continuous and 22A peak currents.

The series is designed  for operation of multiple electronics and other high-power systems; commonly needed when linear BECs are not capable of handling the power requirements (such as those included in many off-brand ESCs) or when using high-grade, OPTO-isolated ESCs (such as the KDE Direct UAS Electronic Speed Controller (ESC) Series). The UBEC allows for selection of four voltage ranges: (1) 5.0V, (2) 6.0V, (3) 8.0V, and (4) 12.0V - providing voltage-regulated and extremely low-noise power for flight controllers, servos, and even cinema-grade aerial-photography applications.

UBECs include 200°C, 20 AWG silicone-wire power-input leads and 22 AWG silicone-wire power-output leads (triple-format) with standard servo-lead connectors pre-installed. ф3.5mm (KDEXF-BC35) and ф4.0mm (KDEXF-BC4024K matching Bullet Connectors are included for the power-input leads; providing simple plug-and-play compatibility with most power-distribution boards and UAS applications.


Programming: User-selectable voltage regulation: 5.0V, 6.0V, 8.0V, 12.0V
