SUBSYSTEMS
1000 W Power Supply
The TX1000 series single-output, 1000 W power supply with active input power factor correction circuitry accommodates a 90 to 264 VAC input for global applications. Standard output configurations include 3.3, 5, 12, 15, 18, 20, 24, 28, 36 and 48 V models to support a wide range of needs including front ends for distributed power architectures. All models (except the 3.3 and 5 V) have an optional ORing diode, which, when combined with the active current sharing feature, provides an N+1 redundant platform for fault-tolerant applications. Standard features include power fail warning, remote inhibit, DC OK signal, current share, over-voltage protection, output over current/short circuit protection and remote sense. The logic signals can be configured either active high or active low.
