ATI AT1820 SERIES

מפרט טכני 

Remote Trigger-Activated from 3.3VDC to 24VDC
Protection Circuits -Optically – coupled with full automatic reset.
Toroid Transformers-40% more efficient than EI type. Separate bi-filar windings for each channel guarantee lower noise and crosstalk.
Circuit Boards-Double-sided FR-4 glass epoxy, computer-grade boards are assembled in California.
Soft Start Circuitry-Soft-start minimizes in-rush current. Multiple units can be turned on without tripping circuit breakers, eliminating the need for turn-on sequencing.
Power Transistors-High current, bi-polar output transistors ensure optimized performance in real time.
Power Supply Capacitance -22,400uF per channel.
Power Cord -Detachable, 3-wire power cord.
