NQ3 Series Dual Power ATS
- NQ3 series dual power ats (follow brief as setting) is one of adopted international
technology developed by our company. The setting is suits for AC 50Hz, rated working voltage is 400V, rated
current 6A-100A and under dual power supply system. It has over voltage, under voltage, lost phases protection
function. The setting mainly used for hospital, shopping center, bank, and chemical industry, metallurgy, high
building, military facilities.
Small volume, high breaking, short arcing and compact structure
«Complete protection function, with short voltage, over voltage, phase faulty and under voltage etc protection.
«Communicate with EPS fire control power, DC24V can remote separate steably.
«No noisy, save on energy and mounting conveniently
Transfer switch is composed with 2 sets MM5-63 MCB and motor mechanism rotating device, through circuit
breakers to inspect the two way power. When the circuit abnormal, the controller will make a logic determine
with the inspect result. According controller order to drive the operate mechanism on or off, thereby supply
electric security and steablity.
