NYKP Series

Dual Power Automatic Transfer Switch

NYKP2 series(16A-3200A)

NYKP1 series(6A-630A)

Intelligent Fast Safe Comprehensive

PRODUCT OVERVIEW

Dual power automatic transfer switch is a power conversion equipment, featuring fast response, strong stability and high reliability; it has the protection functions for short circuit, grounding, phase loss and over-voltage; widely used in power plants, substations, coal mines, ports, factories, airports, and other important places for the protection of circuits and equipment safety, realizing intelligent control and management.

FAST RESPONSE AND SWITCHING

Dual power supplies are driven by motors and solenoids for fast.

ISOLATION FUNCTION MAKES USERS MORE ASSURED

The front end of the product can be set with an isolation switch or with isolation function,providing obvious line disconnection points to protect personal safety during maintenance.
