저전압 육상 전원 공급

제품 특징

This product is specifically designed and manufactured for harsh operating environments such as oil wells, oil fields, ships, ports, and construction sites, where exposure to high temperatures, high humidity, high corrosivity, wind-blown sand, and heavy load impacts is common.
Outdoor-type container design with an IP65 protection rating. The technical parameters of the internal inverter power supply are identical to those of the Ay60 series three-phase inverter power supply.
Complies with GB/T25316-2010 “Stationary Shore Power Supply” and meets the marine product certification standards of China Classification Society (CCS).
Complies with GB/T 7260.3-2003 “Uninterruptible Power Supply Equipment (UPS) – Part 3: Methods for Performance Determination and Test Requirements” and GB/T 14549-1993 “Power Quality – Harmonics in Public Electric Power Systems”.
All PCBs undergo a coating curing process.
The output transformer is treated with true vacuum impregnated insulating varnish and high-temperature protective spray coating, offering a high insulation class and strong protective capabilities.
Equipped with multiple protective devices to ensure system safety and normal operation.
Equipped with an input metering cabinet unit that displays measured values such as voltage, current, power, power factor, and electrical energy.
Equipped with a multi-outlet distribution metering unit for distributing power to end-users; this distribution unit features multiple protection devices against overvoltage, undervoltage, overcurrent, short circuit, and overload conditions. Additionally, it can measure and display parameters such as voltage, current, power, power factor, and electrical energy for each power outlet.
Based on the user’s on-site application requirements, each power distribution output can be equipped with a dedicated cable connection interface to facilitate quick and easy connection.
Supports both wired and wireless data transmission services to collect system data via a computer and monitor system operation.
