SmartGen BTM300 Dual Power Transfer Module
OVERVIEW
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 automatically chooses output power source based on the voltage situation. BTM300 is widely used in Marine and stationary generation units with compact structure and easy installation.
PERFORMANCE AND CHARACTERISTICS
- Suit for dual-power DC power supply system.
- According to the voltage situation select power supply. Choose V2 if both are available; and choose V1 if V2 is unavailable.
- Corresponding LED indicators will display the situation of V1 and V2; meanwhile, relevant relays start output.
- 35mm guide rail installation or M4 screw mounting.
- Modular design and pluggable connection terminals; compact structure with easy mounting.

FUNCTION DESCRIPTION
BTM300 Dual-power Transfer Module is aiming at providing uninterrupted
power supply to realize dual-power seamless switching.
The mainly function of BTM300 is to select power source according to the
voltage situation of double power supply. V2 is main power source, thus module
will select V2 when both power are available, which means output voltage V is
supplied by V2; When V2 is unavailable, the module is supplied by V1. When V1
is available, LED besides V1 POWER lights up and V1 (7A) relay OUTPUT action
initiates; When V2 is available, LED besides V2 POWER lights up and V2 (7A)
relay OUTPUT action initiates.
