High-voltage coreless servo (HVC)
High-voltage, 2-cell LiPo batteries provide a direct power supply. This is the new product range from the digital servo segment, HVC (high-voltage coreless servo).
With a maximum permissible operating voltage of 8.4V, the new battery technology can be used without reservation. Naturally, these servos can also be operated with a conventional 6.0 V supply. The very best production quality tops off this line of our servos.
