ATS320AC Automatic Transfer Switch Controller with USB Port, Real‑Time Voltage Display, Generator ATS Control Module

ATS320AC Dual Power Automatic Transfer Switch Controller Module Compatible as a replacement for HAT530N and ATS530 controllers Description A mains and generator automatic transfer switch controller designed for one mains and one generator supply. The ATS320AC provides automatic and manual control of an ATS dual power switch, continuous monitoring of mains and generator parameters, and comprehensive fault display and protection to prevent damage when the generator does not run normally. The compact module uses a 32 bit microcontroller for reliable operation, simple wiring with Europeanstyle connectors, and an IP65 rated front gasket for installed environments. Key benefits Reliable automatic transfer and protection: Automatically transfers between mains and generator and provides clear fault display and protection functions to reduce the risk of equipment damage when the generator behaves abnormally. Clear monitoring and status feedback: Onscreen display of generator and mains voltages and frequencies and LED indication of operating mode for fast diagnostics. Flexible control and configuration: Operate in manual, automatic, test, or shutdown modes. Configure all parameters via front panel buttons or by USB connection to a PC, even when the controller has no power. Easy installation and compatibility: Compact module design, standardized European connectors and simple wiring make replacement and retrofit straightforward. Compatible as a replacement for HAT530N and ATS530 controller modules. Main features 32 bit performance single chip microcomputer for stable control. Screen with Chinese and English interface. Additional languages available on request. Displays generator voltage, generator frequency, mains voltage, mains frequency and phase information. Modes: automatic, manual, test, and shutdown. LED indicators show ATS switch working status. Supports common AC systems: three phase four wire, single phase two wire, and two phase three wire. Inputs and outputs: 3 relay outputs and 2 configurable switch inputs. USB port for parameter setting and real time monitoring; parameters can be set via USB even without controller power. Control protection: automatic ATS switching for generator sets plus detailed fault display and protection functions. Durable sealed front with waterproof rubber gasket providing IP65 protection. Module design with European connectors for reliable connections and simplified wiring. Typical applications Backup power for commercial and residential buildings where automatic transfer between mains and generator is required. Power control for small to medium sized generator sets in construction, rental, or standby applications. Support for critical systems such as telecommunications equipment rooms and local server racks that need fast and reliable transfer and fault indication. Configuration and operation All settings can be adjusted using the front face buttons or via the USB programmable interface connected to a PC. Language options include Chinese and English by default, with additional languages available on request. The unit is intended for integration into ATS panels and power control systems where a compact, reliable transfer controller is required.
