Series Overview
Intelligent Controllers
• ATS021 Intelligent Controller is a standard-type controller designed to work with two circuit breakers (molded case or air circuit breakers) featuring mechanical interlocks and motorized operating mechanisms. It can be applied in:
- Three-phase three-wire distribution systems (requires a 380/220V a.c. conversion transformer)
- Dual-power distribution systems between 60Hz mains and generators
- Features wide voltage application range, supporting up to 480V three-phase distribution systems.
• ATS022 Intelligent Controller is an advanced-type controller that also pairs with two interlocked motorized circuit breakers. Beyond ATS021's basic functions, it offers:
- User-friendly HMI (Human-Machine Interface)
- Broader power frequency options
- Extended operating voltage range (100-480V)
- Configurable operation delay (up to 30 minutes)
- Circuit breaker status monitoring
- Non-critical load shedding command capability
- Communication module
- Fault memory (up to 20 recorded faults)
• ATS022 with Bus Coupling Function:
When paired with two time relays, ATS022 enables bus-tie switching:
- Under normal dual-power operation, loads are separately powered by two sources
- Upon one power source failure:
- Disconnects the faulty source
- Closes the bus-tie breaker
- Transfers all loads to the healthy source
- Typically deployed in mission-critical applications requiring ultra-high power continuity.
• Note: When ATS021/ATS022 controllers are independently configured with circuit breakers, they can form automatic transfer switches (ATS) supporting currents up to 6300A.
