BTM300 Dual-power Transfer Module is especially designed for dual DC power transferring to realize generator-set uninterruptible power supply output with double power sources input. It is automatically choose output power source based on the voltage situation.

BTM300 is widely used in Marine and stationary generation units with compact structure and easy installation.


a) Suit for dual-power DC power supply system.

b) According to the voltage situation select power supply. Choose V2 if both are available; and choose V1 if V2 is unavailable.

c) Corresponding LED indicators will display the situation of V1 and V2; meanwhile, relevant relays start output.

d) 35mm guide rail installation or M4 screw mounting.

e) Modular design and pluggable connection terminals; compact structure with easy mounting.
