Overview
Some equipment has low requirements to the voltage (within 5%), based on the users’ suggestion, we developed the ZBW series economic type voltage stabilizer that is featured with compact volume, quick response, brushless, contactless, machinery free, three-phase separated regulation, it is economical and practical.
Voltage stabilization accuracy of ZBWL series intelligent contactless AC voltage stabilizer (economic type) is 5%, its outline dimensions, technical indexes and performance features are same as ZBW series.
Application
Various CNC machining centers, medical equipments, printing machineries, environmental test facilities, communication equipments, etc, especially suitable for severe power supply environment such as large grid voltage fluctuation range, abrupt change of voltage, etc; it is applicable for situations that the equipment voltage is different from the power grid voltage; CNC machining centers, medical equipments, printing machineries, environmental test facilities, electronic test equipments, communication equipments and so on with different voltage systems.
