DC power backup |
摘要 |
A barrier movement operator with a backup source of DC power is disclosed. The power supply of the barrier movement operator sends current limited DC to the backup which uses the DC to charge a battery. The battery is in circuit at all times with the barrier movement operator power supply by means of a power diode and, when an AC mains power failure occurs, DC power is sent from the battery to power the barrier movement operator.
