Backup power sources ASTIP RECTIFIER series To power supply the elevators, controlled by frequency converter Backup power sources Rectifier are designed for devices which motors are powered and controlled by frequency converters. Use ability of frequency converter, namely the possibility of DC power via DC voltage terminals.It offers very cheap and reliable backup.Sources Rectifier include "only" DC inverter with stable voltage suitable for powering FC, logic of switching between electrical network and output UPS, control logic and evaluation of hazardous states, battery charger. It also contains a source of 230V sine ON-LINE or OFF-LINE to power other devices of elevator such as doors, lighting, .. .Source Rectifier can be delivered in off-line and online, they can be used as a power source for fire protection of electrical equipment Financial savings Because do not contain the most expensive item - 3x400V inverter, which is for the complexity and vulnerability to overload the most expensive part of the normal UPS 3-3, the sources Rectifier able to save 50-70% of the cost of the backup. The architecture complies the requirements: Supply fire protection equipment Architecture and management of backup resources ASTIP PS series was created in accordance with the requirements of the fire safety of buildings CSN 73 0802, 73 0804, with no. 23/2008 Sources of matching these prescriptive requirements: The two independent sources. The sources with direct links powered devices The PBZ power without any additional devices The direct control signal fire and TOTAL STOP. TOTAL STOP off power is vitally important, not to leave dangerous voltage of the object. The above properties lead to another savings during the project implementation Additional technical data 200-500V DC power supply such as roll 400-800VDC power supply frequency converters with full power Power range from 1800VA to 150kva The output voltage 3x230, 3x400V, 50 HZ Auxiliary power supply: 230V, 50 Hz ONLINE type of sine output to power any helper equipment. Resources need not air-condition at room in which are located For design of sources we cooperate with manufacturers and suppliers of elevators in the country. These resources have been deployed such as elevators Ostrava, El-You, Pardubice, Lifts, Elevators Pilsen in cooperation with Vsetin limit.
